Denture Cream Zinc Poisoning a Confirmed Problem by the FDA

In what will seem like old news to my long-time readers, the FDA announced earlier this month that they have confirmed cases of denture cream zinc poisoning causing nerve damage. Actually, they use the term “overuse,” but the reality for many poor denture wearers is that overuse is an everyday occurrence. Specifically, they mention that

…an excess of zinc in the body can lead to health problems such as nerve damage, especially in the hands and feet. This damage appears slowly, over an extended period of time.

Overuse of zinc-containing denture adhesives, especially when combined with dietary supplements that contain zinc and other sources of zinc, can contribute to an excess of zinc in your body.

Nothing earth shattering there. In fact, I’m somewhat disappointed that they are not yet admitting that even normal use can lead to these issues over time, as was the case for my mother. They also wisely note that

In most cases, properly fitted and maintained dentures should not require the use of denture adhesives. Over time, shrinkage in the bone structure in the mouth causes dentures to gradually become loose. When this occurs, the dentures should be relined or new dentures made that fit the mouth properly. Denture adhesives fill gaps caused by shrinking bone and give temporary relief from loosening dentures.

Again, not really news to folks who follow this site. After all, I’ve been recommending that folks use an inexpensive, at-home denture reline kit for ages. While I’m sure every denture wearer would love to have a fresh new set of dentures every year or two, it simply isn’t financially feasible for most.

So if you’re still using a zinc-containing denture adhesive, please stop! Switch to a denture cream without zinc, such as reformulated Poligrip or Secure Denture.

Better still, switch to a more natural form of denture adhesive. Since many folks’ old favorite Rigident was taken off the market, I’ve been recommending Klutch as a close second, since it contains ingredients you can actually pronounce and understand!

So while I’m happy the FDA is finally moving to make recommendations based on the claims of denture cream zinc poisoning in the medical literature, I feel they still have a long way to go. The best way I can think of to get this point across to them would be to have everyone who has suffered damage due to the zinc in their denture adhesives use this form to report to them their story to the FDA.

Denture Adhesive Powders Without Zinc

It seems that many folks visiting my site these days are interested in Denture adhesive powders, rather than other useful information like denture cream reviews. If you’re new to the site, you may not know that I’ve already covered Rigident in detail (in this post) and also confirmed that Rigident contains no zinc. Shortly after I did so, however, the folks who make Rigident decided to discontinue production!

If you are a big Rigident fan, you’ll probably want to do the following things:
1. Check prices on remaining stock by clicking here. If you find any at a reasonable price, snap it up!
2. Sign the petition to bring back Rigident! I have created a petition to Church & Dwight to let them know how many people their marketing decision has affected. Please click here and sign the petition, and then email all of your denture-wearing friends (and heck, anyone else you think would be interested!) and have them sign it as well!

Of course, if you never used Rigident, you’ll probably never miss it, so I wanted to spend some time talking about the other zinc-free denture adhesive powders available, at least on the American market. I’d love to cover international products eventually as well, but since the majority of my traffic is still coming from the US these days, I’ll start here at home. :)

The first name that sprang to my mind is Klutch, since I had recently done a little digging to find out about its ingredients. As I did so, I discovered that aside from the no-longer-available Rigident, it had the least scary-sounding list of ingredients. I also saw that its reviews were more good than bad. I suppose like any denture adhesive, there will be some for whom it does not work. Fortunately, there are those who swear by it. I am always happy when a product with relatively benign ingredients actually works! It always makes me feel better about recommending it (though if I were to begin wearing dentures tomorrow, I’d probably try it even if the reviews were less than favorable. I have learned the hard way that what we put into our bodies makes a HUGE difference in our health!). And as you would expect from any adhesive featured on my site, it is completely zinc-free. In doing my research, I also learned that this brand has been on the market for over 70 years. I would think that no product would survive for so long if it didn’t work (and work well) for the vast majority of its users! You may check prices on Klutch by clicking here.

Another powdered brand I took a good long look at is Poligrip Denture Adhesive Powder. Actually, I think its full name is “Extra Strength Super Poligrip Powder,” but since there is no regular strength adhesive powder put out by Poligrip, I don’t feel too bad shortening the name. :) That said, the name isn’t the only thing that’s long about this product. One of its ingredients, in particular, was long-winded and a bit difficult to research (poly(methylvinylether/maleic acid)). Still, it contains no zinc, and its reviews are, as of this writing, all positive. I imagine this is due in part to the fact that Poligrip is a better-known brand in denture adhesives, so it undoubtedly has more users than Klutch. Still, there is something to be said for a company that puts out a product which works, AND contains no zinc, regardless of the pronounce-ability of their ingredient list. You can have a look at the reviews by clicking here, or check pricing on different sizes (single vs. multi-packs) by clicking here.

Finally, I ran across a product called Super Wernets, or sometimes also known as Poligrip Ultra Wernets. While I found this a bit confusing at first, I finally discovered that the Poligrip Extra Strength mentioned above, and Super Wernets, were both made in Ireland, and had the same ingredients. Apparently Super Wernets is (or was; there is some disagreement over whether the product is still made under that name) the same product, made at the same factory, and owned by the same parent company. The only difference I could confirm between Super Wernets and Poligrip Extra Strength powder was the name. My best guess is that they manufacture it under one name for sale in some areas of the country (or world), and under the other name in other areas. Nothing so groundbreaking about that, but it can certainly be a bit confusing for those of us who might once have been big fans of Super Wernets, only to watch it disappear from store shelves, all the while not realizing that its twin sister was sitting right next to us in the form of Super Poligrip! If you really prefer the Wernet’s name (or if you just want to compare pricing between Ultra Wernet’s & Poligrip), you can check pricing here.

Denture Cream Without Zinc - An Update

I’ve been focusing on denture adhesive powders a lot lately, mostly because that seems to be what I get the most questions about. However, I realize that there are still a lot of people using denture creams. Although I’ve posted in the past about various denture creams separately, and as they’ve gone zinc-free, this site has been lacking a single, comprehensive post about your options when trying to choose a denture cream without zinc – until now! The three shown below are the best, as ranked by the folks who use them. I encourage you to click on them and check out their review pages for yourself, since the ratings shown on this page are accurate as of the date of this post, but may very well change over time.

Highest-Rated Denture Creams Without Zinc

First up is my old favorite, Effergrip. Why is it a favorite? Primarily because they’ve been zinc free for years (possibly forever; I’m having difficulty locating current ingredients, much less historical ingredient listings). It’s also a favorite because it is the most highly ranked denture cream without zinc. Of course, it is possible that it contains other ingredients which have their own hazards; all I can say for certain is that when I get to the bottom of their ingredient list, my readers will be the first to know!

Next we have Secure Denture Adhesive. While they once marketed themselves as a “natural denture adhesive” I see they have mostly removed that branding from their web site – and rightly so. Their product contains Polyvinyl Acetate, which they now admit is a fully synthetic substance. They state that they do this for quality purposes – to achieve a standardized product – which is a reasonable choice. I could find no evidence that Polyvinyl Acetate is detrimental to human health. In fact, it is listed as a permitted additive by the FDA, both for chewing gums and for “drug mixtures which are exempt from certification.” Secure insists that this ingredient is totally inert, so for now I’m giving it the benefit of doubt and calling it an acceptable risk.

Zinc-Free Super Poligrip. This has been reformulated in the past year to remove the zinc which triggered so many lawsuits. While it’s a bummer that lawsuits had to be brought in order to get them to remove a potentially harmful ingredient, the net result is good. While it still contains ingredients which have scary chemical-sounding names (the only way I’ve found around this problem thus far is to go with a powdered denture adhesive, like Rigident), it is one of the older and more popular brands in the industry, so I am glad to see them putting out a full line of denture cream without zinc. Given its popularity, it’s available on almost every store shelf (as well as online here), so the fact that they’ve removed the zinc can only be a good thing.

If you’re wondering why “the F word” (that is, the major brand of denture cream on the market which begins with an “F”) is not listed here, it’s for a very good reason: they have not changed their formulation to exclude zinc – and it appears that they have no plans for doing so! I don’t even want to mention their brand name here, lest they get a “good rep” by being associated with this site. I think it’s shameful that even in the face of overwhelming scientific evidence and legal pressure, they refuse to admit that the zinc in denture cream could be a health hazard. I’m hoping that perhaps someday there will be legislation forcing them to clean up their act.

Poligrip Denture Adhesive Powder Ingredients

In keeping with my ongoing research into the ingredients of various denture adhesives, today I decided to look into Extra Strength Super Poligrip Powder. It’s the last of the major brands of denture powder here in the United States, and probably one of the more popular options for people who prefer zinc free denture powder over zinc free denture cream.

According to the Poligrip manufacturer web site, the ingredients of Poligrip denture adhesive powder are as follows: Cellulose gum, poly(methylvinylether/maleic acid) sodium-calcium mixed partial salt, flavor. Here is my breakdown of what I could find out about these ingredients.

Cellulose gum: As with so many other denture adhesive powder ingredients, this has both a natural-sounding name (cellulose gum) and a chemical-sounding name (carboxymethyl cellulose). The good news is that this ingredient is non-toxic, and is very commonly used in food products around the world. There is actually no MSDS (Material Safety Data Sheet) for it, though there is an MSDS for the sodium salt of carboxymethyl cellulose. However, even in that form, it seems that it’s the sodium which causes the toxicity, as the LD50 (lethal dose in 50% of a test population – generally composed of rats) is 27,000mg/kg. For a 180 pound human, this would amount to consuming nearly five pounds of the stuff in one sitting. The only other mention of issues is with inhaled powders. Since I don’t think anyone is interested in snorting their denture adhesives, I dismissed that as a concern. So I happily chalked this up as a very benign ingredient and moved on.

Poly(methylvinylether/maleic acid) sodium-calcium mixed partial salt: I have actually had some difficulty trying to hunt down information on this ingredient. I found several variants of the name, each of which seemed to possess different properties. According to Good Guide, Poly (methylvinylether/Maleic Acid) does not raise any red flags because it has not been found in human tissue or urine. And the makers of Poligrip branded products clearly believe it’s a safe ingredient to use, as you’ll find it’s listed in every one of their denture adhesives except for their Comfort Seal Strips.

Me? I’m not quite as convinced. For one thing, maleic acid, when viewed as a separate entity, has been shown to be toxic to the kidneys. Furthermore, if the compound in question is, as I suspect, also known as methyl vinyl ether/maleic acid copolymer, then it has an MSDS which states enigmatically “May be harmful if swallowed.” All that said, I couldn’t find any data suggesting that this particular ingredient is actually harmful in the small doses a person would receive when using it as a denture adhesive. As with the cellulose gum above, even the information I found about toxicity (like the maleic acid alone, which I should stress this denture powder does not have) all indicated that you’d have to consume massive amounts in order to poison yourself.

Flavor: Well, here’s a wide open ingredient if ever I’ve seen one. I actually hate it when companies use this sort of terminology. Reason being, I learned long ago that they generally use it to hide something. For example, did you know that if a product contains monosodium glutamate (MSG), they don’t have to state it on the label, but can instead use one of the following obfuscating names for it:

Hydrolyzed Vegetable Protein
Hydrolyzed Protein
Plant Protein Extract
Sodium Caseinate
Calcium Caseinate
Yeast Extract
Textured Protein (Including TVP)
Autolyzed Yeast
Natural Flavor

And that is only a partial list. Pretty crazy, huh? So the reality is, we have absolutely no idea what this “flavor” is in Poligrip Denture Powder. It could be something as benign as peppermint oil or as scary as, well, something with 18 syllables that I can’t pronounce. I’m pretty sure it’s not MSG, though. :)

So, all that said, what do I personally think of the ingredients in Poligrip denture adhesive powder? I think if this is a product you’ve been using for a while, and you haven’t had any mysterious or unexplained health issues, then you’re probably fine to continue using it. However, if I were to need dentures myself today, I would probably err on the side of safety, and select a product with less cryptic ingredients, like Klutch.

Klutch Denture Adhesive Powder Ingredients

I’ve been doing some digging lately to find out more about the ingredients in people’s favorite denture adhesives. The reality is that while most companies have removed zinc from their denture adhesives, there may still be worrisome ingredients in some products. Today I’m tackling Klutch Denture Adhesive Powder, which may be purchased online here, if the reader is so inclined.

Klutch’s simple ingredient list is as follows: Karaya powder, acacia gum, sodium borate, and methyl salicylate.

If you’ve read my post about Rigident ingredients, this list will likely look very familiar. The first three are exactly the same (though Rigident calls sodium borate by another name: impalpable borax), so if you’d like a rundown on what the first three are and their relative safety, please see my post on Rigident’s ingredients.

So what about the remaining ingredient, methyl salicylate? Methyl salicylate, though it has a very chemical-sounding name, is also known by another, much more benign-sounding name: oil of wintergreen. This reminds me strongly of acetylsalicylic acid…better known as aspirin. And in fact the two are chemically related, as both contain salicylate. But is methyl salicylate safe? After all, it is on a list of prohibited and restricted cosmetics ingredients in Canada, which automatically triggers doubts about its safety. But I urge you to consider the small dosage we are talking about here, as well as some other circumstances.

For example, consider the fact that aspirin is also known to be toxic, when the dose is high enough. Yet when used sensibly, it can not only relieve pain, but has been credited with saving the lives of many stroke and heart attack victims. Likewise, while pure methyl salicylate is toxic at certain doses, the dose you’d be getting when using Klutch powder as directed would be a tiny fraction of a dangerous dose (remember, in the US, ingredients are listed in decreasing order by the amount contained, so methyl salicylate is, proportionally, the least-common ingredient in Klutch). Still, as we learned the hard way with the zinc in denture adhesives, the devil is in the dosage. So if your dentures are becoming loose, and you have to use more than a light dusting of any denture powder, you will want to either invest in an at-home denture reline kit (available in both soft and hard versions), or speak with your dentist about having him or her do a reline.

Three special considerations that I discovered during my research about salicylates (including methyl salicylate):

1. Many muscle rubs contain salicylates, such as Bengay (methyl salicylate), Icy Hot (methyl salicylate) and Aspercreme (trolamine salicylate). If you use these muscle rubs, you might have noticed the warnings on the package that say “for external use only,” and this is for a very good reason; they contain relatively high amounts of the listed salicylates (as much as 30%, in the case of Icy Hot). Thus ingesting them would almost certainly produce negative (poisoning) effects. What you might not think of, though, is that if you use both a muscle rub, and Klutch, there may be an additive effect of salicylates (yes, salicylates can penetrate the skin and be absorbed into the bloodstream). Again, the devil is in the dose. So while I’m not saying “don’t use Klutch and Bengay at the same time!” what I am saying is that if you use both, be sure to use both in moderation. Of course, using any muscle rub in moderation is advisable, as there is at least one death on record from excessive muscle rub use.

2. If you have an allergy to aspirin or other salicylates, I would not recommend using Klutch. Even though the amount is tiny, why take chances?

3. If you are young (of reproductive age), and/or are planning on having children, I would recommend avoiding Klutch. Remember that I mentioned it was on a restricted list in Canada? Well their reasoning for that is due to developmental and reproductive toxicity. So while most denture users are likely beyond a point where they’re trying to conceive, I realize that there are still many people (like my mother) who lose their teeth young due to genetic defects, accidents, and other unfortunate circumstances. Given that there are other great denture adhesive powder options on the market, I see no reason to take any chances with the health of your unborn child.

So, can I recommend Klutch? Yes, as long as you are taking into consideration the above caveats. That said, I’m a firm believer in the principle of less is more, so given the fact that Rigident receives rave reviews (see them here) while having one less ingredient, if I were making the decision for my own use, I would probably try Rigident first.

Denture Cream Without Zinc Important in Correcting Denture-Related Zinc Poisoning

Effergrip Box PhotoI was poking around on PubMed (the free online article repository made available by the National Institutes of Health), and found not one but three research articles which have been published in the past two years that link the zinc in denture creams to myelopathy and/or neuropathy. Of course, there are several older articles as well, but my point here is that evidence is mounting in the case against zinc in denture creams, and none of it is good. On the flip side, switching to a denture cream without zinc (like Effergrip) can make a big difference. Read on for more info on how!

First off, I wanted to define a couple of terms for you; it seems that though neuropathy is a term more often used in the media (and on lawyers’ web sites) to refer to the damage caused by excess zinc from denture cream, the more correct term would be myelopathy. Neuropathy is defined as “a functional disturbance or pathological change in the peripheral nervous system”. On the other hand, Myelopathy is defined as “any functional disturbance and/or pathological change in the spinal cord,” or “pathological bone marrow changes” (myelopathy has two definitions).

To put these definitions in something closer to layman’s english, it appears as though myelopathy is a problem caused by damage to the spinal cord, whereas neuropathy is a problem caused by parts of the nervous system which branch off from the spinal cord.

That said, when you talk to a person suffering from neuropathy or myelopathy, they probably don’t much care whether the problem lies within or beyond their spinal cord. More than likely, they just want to cure the problem!

According to the case studies featured in this research, the news for people interested in curing their myelopathy and/or neuropathy is mixed. According to this article in particular, which features the case studies of two individuals, there are four main problems caused by use of zinc-containing denture creams: hyperzincemia (too much zinc in the blood), hypocupremia (too little copper in the blood), pancytopenia (a lack of red & white blood cells and platelets), and myelopathy (which results in pain and difficulty walking for the patient). Of these four issues, the first three are completely resolved by stopping the use of the denture cream and starting supplementation with zinc. The fourth issue, the myelopathy, is only partially resolved; while the patients no longer reported pain after their copper and zinc levels have been normalized, they still had difficulty walking.

While this last point is a less-than desirable result, the reality is that correcting your zinc/copper imbalance by switching to a zinc-free denture adhesive (like Klutch or Cushion Grip) and beginning copper supplementation is always going to be your best possible course of action. Even if you can’t effect a full recovery, you will stop the damage being done, and give your body a chance to use its amazing powers of recuperation!

Rigident Denture Adhesive Powder Ingredients

UPDATE: Rigident has been discontinued! There are three things you can do about this:
1. Check prices on remaining stock by clicking here. If you find any at a reasonable price, snap it up!
2. Look into alternative zinc-free denture adhesives by browsing around this site. If you liked Rigident, you may like Klutch; it has very similar ingredients. Read my review of ingredients here, or check prices here.
3. Sign the petition to bring back Rigident! I have created a petition to Church & Dwight to let them know how many people their marketing decision has affected. Please click here and sign the petition, and then email all of your denture-wearing friends (and heck, anyone else you think would be interested!) and have them sign it as well!

–original post begins here–

A few days ago I made a brief post marveling at the popularity of Rigident. In it, I made reference to the ingredients of a competing brand, Klutch. This got me to thinking, though; what about the ingredients of Rigident?

Since I, like everyone else in the country, can’t find Rigident stocked in my local stores (it may readily be purchased here, however), I wrote to the makers of Rigident, and asked for a list of ingredients. What I learned shocked me, but in a very good way!

Rigident Denture Adhesive Powder ingredients:
Karaya gum, Acacia Powder and Impalpable borax.

I’m not sure I’ve seen such a short ingredient list on a product in years! And to my mostly untrained eye, they appeared to be very benign. But to be on the safe side, I went ahead and did a little research on each.

Karaya gum is a natural vegetable gum, like guar gum or chicle, and most often used as a thickening agent in foodstuffs. The only warnings I could find about this substance were in regards to its use in ostomy supplies (due to the possibility of infection) and as a choking hazard when delivered in a dry form in large amounts. It’s a certified food additive, and has the FDA’s “Generally Recognized as Safe” (GRAS) designation, and has been tested in humans (abstract here) without showing any toxicity.

Acacia Powder is another natural vegetable gum, also known as gum acacia or gum arabic. It is used as a food stabilizer and thickener, and also has achieved the FDA’s GRAS designation. There is an abundance of information about it on the web, and it appears to have been used for many, many things, including the control of IBS (Irritable Bowel Syndrome), by many for years with no side effects. It has even been studied as an anti-malarial! (scientific abstract available here)

Impalpable borax (which means sodium borate that’s been very, very finely ground) was the scariest-sounding ingredient. It is a mineral salt of boric acid and, while I have known for years that boric acid is approved as a food additive by the FDA, borax is not. Oddly, it is approved as a food additive by the European Union; usually it’s the other way around – the EU tends to ban things before the US. You will find a great deal of controversy over why this is the case; supporters of alternative practitioners like Dr. Hulda Clark will say that this is a conspiracy by the pharmaceutical companies. Whatever the real story, despite its antimicrobial properties, it can’t be used in food. It can, however, be used in small quantities in over-the-counter products, such as Rigident.

One other thing I wanted to mention is that borax is listed as the last ingredient in Rigident. In the US, ingredients must be listed in order of their prevalence in a product, from highest to lowest. This means that of the three components, the ingredient appearing in the smallest quantity is impalpable borax. I took a look at the MSDS (Material Safety Data Sheet) for borax, to find out if the tiny amounts used in Rigident could really cause issues. According to the MSDS, “small amounts (e.g., a teaspoonful) swallowed accidentally are not likely to cause effects; swallowing amounts larger than that may cause gastrointestinal symptoms.” Given that denture users are likely using 1/8th of a teaspoon or less of total product, and considering that only a small percentage of that product is comprised of borax, I would call this a very reasonable risk.

Naturally, each person will have to judge this for themselves (and there may be folks who react poorly to Rigident, though thus far I have not heard from any of them) whether or not to use Rigident. We must also realize that if we were to dissect every ingredient in every product we consume the way I have here, two things would happen:
1. We wouldn’t consume very much, as this is a very labor-intensive process!
2. We’d find much scarier ingredients being used in much larger quantities in products sold as food (sodium benzoate and monosodium glutamate come to mind).

So as always, my advice comes down to this: make sure that your dentures fit as well as possible, so that you use as little denture adhesive as possible. One of the least expensive ways of doing this is to use a denture reline. I’ve said this before, and I will continue to preach it for as long as I have this site: too much of a good thing is bad! So go ahead and stock up on Rigident, but make sure that if you notice your consumption increasing, that you look into a denture reline (or new dentures, if relines are no longer working for you).

What if You Weren't Allowed to Reverse Your Zinc Poisoning?

I know that sounds like scare mongering, but it’s really important that I get your attention for a minute. You see, there are forces working to prevent United States citizens from the free access to vitamins, minerals and other dietary supplements we currently enjoy. For starters, currently making its way through congress is a piece of legislation that could make it much more difficult for Americans to access vitamins and supplements needed for our health. It’s called Senate Bill 1310 (full text here). In addition, the FDA is preparing to begin very stringently regulating the production of supplements, such that no one but the most wealthy companies will be able to afford to produce them (full text here).

Why should you be worried about this?

At the moment, simple copper capsules like I myself take cost (TwinLab brand) about $6 if purchased from an inexpensive site like Amazon. Even less (currently 2 bottles for $4.49!) if you buy from Puritan’s Pride! But if you look at what has happened to the prices and availability of supplements in Europe since similar regulations have passed, you will likely have to pick your jaw up off the floor. Just for starters, I did some simple price checking for your edification. Here is what I found:

-DHEA, 25mg, 120 caps at Amazon.com: $3.99 for Swanson brand.
-Pure DHEA isn’t even available on Amazon.de (the German Amazon site) at all; I have it on good authority (from a military friend living in Germany) that you must now have a prescription for DHEA in Germany! Amazon.de does offer a wild yam version, but there’s no good (read: peer-reviewed) research to support that wild yam extractives have the potency or usefulness of pure supplements.
-Another substance my friend has had trouble getting hold of is a form of B12 called adenosylcobalamine. While you or I could buy this from Amazon.com (it’s in this formulation, if you’re curious), she cannot get it at any cost. While this may seem trivial, I can assure you that to people who suffer from anemia due to a genetic inability to convert the standard supplement forms of B12 into the forms the body uses, it is an enormous problem.

And please don’t think that just because it’s not available on Amazon in Germany or the UK, that it’s still available elsewhere. I checked via those countries’ Google (oh, the wonders of modern computer translation!), and could not find copper supplements or DHEA supplements for sale anywhere in Germany. While this didn’t surprise me (due to my friend’s travails), it definitely scares me immensely!

And it’s the same sad story across the board with almost all supplements; availability is decreasing as Codex Alimentarius standards are being codified into laws, and big pharma companies are reaping the benefits, being the only ones allowed to distribute simple nutritional supplements. Not to mention the fact that you would have to convince your doctor that there was something wrong with you, get tested, and then finally get them to write a prescription for a simple nutritional substance like copper. Don’t get me wrong; I am all for conferring with your doctor and asking him or her to monitor you as you try to recover from zinc poisoning (whether it be induced by denture cream use or not). However, I am vehemently AGAINST having to pay big pharma the big bucks in order to get the simple copper (and whatever other supplements your doctor determines are necessary) supplements needed to assist your body in correcting its imbalances.

If you’re worried about these issues as much as I am, please educate yourself further, and make sure to write to your representatives. There is an enormously informative (albeit very long-winded) article about it here, and the NHF (National Health Foundation) makes it really easy to know how and whom to contact about this on this page. Please don’t let them take away our supplements without a fight!

Rigident

UPDATE: Rigident has been discontinued! There are three things you can do about this:
1. Check prices on remaining stock by clicking here. If you find any at a reasonable price, snap it up!
2. Look into alternative zinc-free denture adhesives by browsing around this site. If you liked Rigident, you may like Klutch; it has very similar ingredients. Read my review of ingredients here, or check prices here.
3. Sign the petition to bring back Rigident! I have created a petition to Church & Dwight to let them know how many people their marketing decision has affected. Please click here and sign the petition, and then email all of your denture-wearing friends (and heck, anyone else you think would be interested!) and have them sign it as well!

–original post begins here–

I never cease to be amazed by how popular Rigident is. Time and time again people come to this site in their search to find a new supplier for this denture adhesive powder (if you’re one of them, you’ll be pleased to learn that it is available online, and usually at a considerable discount, especially when buying in bulk – check here). Apparently, stores all over the country are ceasing to carry it. As I have mused repeatedly in the comments, my best guess as to why is that retailers have decided that the shelf space is better given to another product, though I’m not sure how.

As comments here and reviews on Amazon have proven, Rigident is a very popular denture adhesive. There are other denture adhesive powders on the market, most notably Poligrip (which also has good reviews) and Klutch (which has very hit-or-miss reviews). Yet Rigident maintains a following these others don’t seem to have.

One reason, I’m sure, is that it’s a powder. There seem to be many folks who really don’t like the texture or taste of denture creams, and Rigident answers both concerns – according to most it as little or no taste, and the powder form means there’s no nasty squishiness. Another reason is that it is zinc-free, as I verified for you in this earlier post. Of course, zinc isn’t the only scary ingredient ever to be put into a denture adhesive. For example, Klutch contains Methyl Salicylate, which is on a list of prohibited and restricted cosmetics ingredients in Canada, due to developmental and reproductive toxicity. Now, does this mean that Klutch is a bad product, or inappropriate? Not necessarily. But it is definitely something a consumer might want to take into consideration, especially if they are of reproductive age! Oh, and if you’re curious about it, I do have a separate post about Rigident ingredients.

I’d wager that the biggest reason Rigident has such a loyal following, though, is that it just works. As these reviews show, almost everyone has a good experience with it. While I do believe that factors like individual chemistry, the composition of your particular dentures, and how well your dentures fit all have bearing on how a given product will perform, it seems that Rigident manages to work well for a huge number of people regardless of all these factors. If you’re in search of a new denture adhesive because your old one has been reformulated and no longer works as well, or for any reason at all, you might want to give Rigident a try.

If you’ve had any personal experience with Rigident, and would like to let others know about it, please leave a comment below and share. Your fellow denture wearers thank you!

A Denture Reline - Can it Help Prevent Zinc Toxicity from Denture Cream?

In creating this blog, I’ve researched several options for ways to reverse and prevent the zinc toxicity which can be brought on by the use of zinc-containing denture creams. Recently, though there seems to be a renewed interest in the possibilities held by a denture reline. The question I’m hearing seems to be – will getting a denture reline help me avoid (or reverse) zinc poisoning from denture creams?

From what I’ve been able to see, the answer is yes!

Highest-Rated Denture Reline Kits

While your first action should always be to ensure that you are using a zinc-free denture adhesive, such as Cushion Grip Thermoplastic Denture Adhesive, a close second would be ensuring that your dentures fit as well as they can, so that you need to use as little denture adhesive as possible.

Short of purchasing new dentures, which we all know can be terribly expensive, your best bet is a denture reline.

A denture reline may be done professionally, or at-home, with any of a number of kits that are available. The professional sort of denture reline can cost as much as $400 per plate, which can be cost prohibitive for many folks. At those prices, people generally prefer to save for a full new set of dentures rather than spending almost half their cost on a simple reline. And in cases where the dentures are actually broken, the need for new dentures is clear. For the rest, however, an at-home denture reline kit is generally the way to go.

Denture reline kits that you can use in your own home generally cost a mere $10-$20 per plate…a huge savings over the cost of having a dentist do the reline, and it usually lasts 1-2 years. While the professional relines might last twice this long, generally speaking, there is just no comparison on a cost-per-year basis; the home reline kits win hands down.

While I am planning a longer article soon which will go into more detail regarding which denture reline kits are best and why, you are welcome to check out the brief suggestions pictured above, or head over to the complete selection available on Amazon, where you will find extensive user reviews and information about each. The one thing you can rest assured of is that all of these denture reliners are zinc-free!
