Should You Be Worried About the Toxicity of Denture Adhesives?

There are many problems that dentures have to overcome to be successful replacements for your natural teeth. For example, they have to try to look natural using materials that are most definitely unnatural. Solutions to this problem in the past, such as the use of uranium in denture teeth, haven’t always been wise, and can contribute to serious health risks.

But what about one of the solutions to the problem of denture fit: denture adhesives? Is this another toxic solution to a denture problem?

Most Denture Adhesive Ingredients Are Safe

dreamstime_s_17925339It’s reasonable to be concerned about the potential toxicity of denture adhesives. After all, you are putting it in your mouth every day (unless you’d rather blow your dentures out), and your gums are designed to absorb chemicals from saliva. So if there’s anything toxic in denture adhesive, you can be sure that you’d get exposed to it.

The good news is, though, that the main ingredients in denture adhesives are safe. The most common ingredients surely sound like something naturalist medicine people would warn you about. Polymethyl vinyl ether-malevich anhydride (PVM/MA) and sodium carboxymethylcellulose (CMC) sound like potentially harmful chemicals, but they’re actually not. PVM/MA, for example, was recently reviewed again for its safety, and a thorough panel determined that it was non-toxic and safe.

CMC is really just a derivative of cotton or wood, and is commonly considered safe, with no evidence to portray it as otherwise.

Polyvinyl acetate (PVA) is another common denture adhesive ingredient, but it’s generally inert: it doesn’t interact chemically with your saliva, and it’s a common ingredient in chewing gum.

But There Is Some Concern

However, there is an ingredient in denture adhesives that is worrisome: Zinc. Zinc is a great example of how the dose makes the poison. At recommended levels, zinc is a vital nutrient, but if you get too much of it, it can displace copper in your nerves, resulting in severe and permanent nerve damage.

To make matters even worse: you won’t know whether your denture adhesive has zinc in it or not. The only practical way to protect yourself from this danger is to make sure you’re not using too much denture adhesive.

To Keep from Using Too Much Adhesive

Properly fitting dentures don’t need much in the way of adhesives. They should stay in place quite well on their own. If you didn’t need denture adhesive before, but now you do, consider getting your dentures refitted or relined.

Use only a small amount of denture adhesive. If any of it seeps out when you put your dentures in, that’s too much.

Be aware of symptoms of hyperzincuria. If you start to experience any, such as tingling or numbness in your extremities, stop using denture adhesive and talk to your doctor.

Avoiding Denture Adhesive

If you’re concerned about the health effects of denture adhesives, you can get dentures that will stay in place without any adhesive whatsoever. Implant dentures are anchored in your jawbone, so they always remain in place without the need for any amount of adhesives.
