Asking which is the best denture adhesive is a bit like asking which is the best deodorant. Every denture wearer has their own opinion!
But what I CAN do is tell you the best ones available that I know of. Then you need to try them out to see which one suits you best.
You're probably thinking "well, if my denture fitted, I wouldn't need a denture adhesive!"
BUT that's not true.
We'll take a look at the "how and why" denture adhesives work in a minute. But first . . .
Here is my list of the BEST denture adhesives, based on what my patients have told me over the past 30 years;
I think the best is Fitty Dent, marketed under the name Dentek Secure in the USA, Canada and the U.K.
It claims to be the only non water-soluble adhesive. This means that it doesn't wash out from under the denture. It lasts and lasts!
Secure is available as a paste OR as wafers. It is also free of zinc.
My patients who use Secure tell me that it works very well, and that it does indeed last all day. I would recommend the paste, because you can get a really thin layer inside the denture.
The wafers are also quite thin, but not as thin as a smear of the paste!
Here is some information about the zinc poisoning problem.
Why would you want to use a denture adhesive?
To reduce the movement of your denture on the gums. It's possible to have a denture that is actually a good close fit to your gums, but it doesn't stay in place very well because THE SHAPE OF YOUR GUMS doesn't give the denture much grip.
For example, the roof of your mouth (palate) may be rather low and flat. The denture doesn't get much suction. It can move around on your gums when you are eating, causing irritation to the soft gum tissues, and it will tend to dislodge rather easily.
On the other hand, if the roof of your mouth is high and arched, a denture will get more grip, and be more secure. In this case, the denture will sit snugly in position, and hardly move at all when you are eating.
The poorer the fit of your denture, the less well a denture adhesive will work. This is because adhesives work better when they are THIN. You get the thinnest layer if your denture is a good fit to start with!
As your denture gets older and your gums change shape, you start to get spaces and gaps under the denture. Using a denture adhesive in this situation may help a bit, but the bigger the gaps, the less well it works. And the more adhesive you need. Even the best denture adhesive will not work as well as it could.
Instead of spending more money by using greater and greater amounts of denture adhesive, you would be much better off getting a new set of dentures that fit well. Then you can use a really THIN smear of an adhesive, and your dentures will be stable, secure and comfortable.
So remember; the best denture adhesive is always a VERY THIN LAYER of your favorite product!
