Denture adhesives (also called adherent or simply glue) come in powder, paste or cream form which are used to improve stability and retention of dentures. They fix and tight the dentures in place, preventing any movements and dislodgment of the dentures from the bone ridge or the surface of your gums. There will not by any slippage during speaking or chewing, so it increases your functional abilities to an optimal level.
How does denture adhesive work?
Denture adhesive is applied undersurface of the dentures and on your soft tissues like gum and alveolar ridge. One great feature of denture adhesives is being soluble. When the denture adhesive gets wet, under the pressures of dentures, it flows and becomes inflamed. This makes the contact a tight one that works well against the pressures of dentures on your gums.

As it hydrated, denture adhesives will seal the gaps between the gums and the dentures, which wouldn’t allow food particles to be trapped. In the moisturized environment of your mouth, adhesives will become more hydrated and will increase the sticky and adherence characteristics. You will benefit from a well-fitting and stable denture when your removable dentures sometimes have become uncomfortable or loose.
Bear in in mind that denture adhesive can be used when your dentures need a little more security in place not for unsized, ill-fitting dentures that require readjustment, repair or even replacement by dentist or your prosthodontist. With denture adhesives, no matter what you are wearing in your mouth, partial denture or complete denture, you will definitely speak, eat and make social contacts more comfortably.

Are denture adhesives safe?
Denture adhesive are nontoxic and compatible with oral contact with no major health risks if consumed in recommended amount. However, if you overdose the normal application, you may put your health at risk. Remember to use zinc-free denture adhesives. There are reports according to what both FDA and American College of Prosthodontists (ACP) state about the dangerous side effects of denture adhesives containing zinc. Adhesives containing zinc if used over a long period of time, will cause neurotoxicity, nerve damages, numbing, tingling feelings and more serious health problems, so you should avoid using denture adhesives that have zinc as part of the ingredients. Zinc exists naturally in foods and mineral supplements that we eat, so excess zinc in your body will cause several other health concerns including nausea, diarrhea, vomiting and eating disorders.
Because of health risks associated with dentures adhesives containing zinc, you will likely find zinc-free denture adhesives in the market. As a precaution, ask a dentist for the safety of your denture adhesives and pay attention to the zinc-free properties before buying any denture adhesive.
When do you need denture adhesives?
If you are a denture wearer, you may know and be familiar with denture adhesives to some extent. Sometimes, you need to apply denture adhesives even if you have well-fitted dentures. Denture adhesives can compensate for your unstable and unfit dentures depending on your necessity. The problems arise from certain conditions and situations that call for adhesives to glue your dentures firmly in place. Dry mouth is one such common situation that is associated with numerous background diseases and conditions. When there is not enough saliva or high-quality saliva in your mouth, you should expect that dentures will lose the stability that was expected from natural healthy gums and oral soft tissues.
When to avoid denture adhesive?
Try to remake or have your dentures repaired if the dentures you are wearing aren’t your size anymore and are poorly ill-fitting. A well-sized denture that fits well in your mouth do not need adhesives all the time. You should bear in mind that denture adhesives demand cleaning off from your gums and the denture before each new application. Try to be patient and do your regular oral and denture hygiene care.
How to remove dentures when adhesive is used?
Dentures should be removed overnight to keep up with oral health issues and denture care. So, you may ask how I am going to remove them when I have used adhesives. Adhesives are supposed to hold your dentures in place during the whole day. Therefore, you should use some techniques to get the denture off your gums.
The first technique is to rinse your mouth with warm water for a few minutes to make the dislodgment easier. Then gently brush around the dentures to displace the dentures. You can gargle with a mouthwash or even brushing your soft tissues with toothpaste to facilitate the removal. Another way is to puff out your cheeks with air and then by holding upward or downward the flanges of your dentures, you knock them out of its position.
You may need denture adhesive:
- When you have well-sized dentures but you want more stability and good retention
- When there is not enough natural sticky gums and soft tissues due to oral problems like lack of good saliva or xerostomia, which causes dry mouth and decreased retention and stability
- During adaptation or adjustment period. In the early days of denture wearing times, you may find it difficult to get used to your dentures, so dentures adhesives can make you feel comfortable with a nicely fit dentures in mouth
- When you have undergone an oral surgery procedure or radiation therapies, which may have caused lack of retention due to injuries, side effects or healing periods
- In case of diseases and conditions related to salivary glands, dry mouth and systemic diseases
- Those individuals that take medications regularly and may experience dry mouth. Certain medications will have side effects that can create problems with adhesion of their dentures
- Those individuals who have higher social contacts publicly and require a firm denture to retain their speaking and want a better functionality from their dentures

You shouldn’t use denture adhesives if
- dentures are inappropriate in size or ill-fitting in your mouth over the long period of time
- you don’t follow routine oral hygiene and practice denture care
- there are open cuts or wounds in your gums and oral soft tissues
- you happen to experience allergies with adhesive use
How to use denture adhesive
Follow the instructions for denture adhesive application and the most important guidelines for adhesive use. To achieve the strong retention and stability as well as getting the most expected results, you should be aware of where and how to apply the paste, cream or powder adhesives on your dentures.
- Step 1:
clean the denture surface and make sure that the interior surface, where you should apply the adhesive, is as clean as possible
- Step 2:
in case of using cream, paste or strip, be sure that interior surface should be dry. If you are using powder adhesive, wet the interior surface of your dentures
- Step 3:
prepare the appropriate amount to apply. If you are using cream or pastes, use 3 to 4 pea-sized or dots of strips in each top or bottom denture. Do not fill the entire undersurface with adhesive. Follow the label instructions for the necessary amount.
Remember not to use too much adhesives. Because when you apply too much denture adhesives, for example cream or paste, it will cause oozing the adhesive out to the edges and under the denture once they are inserted in your mouth - Step 4:
apply the denture adhesive. For creams or pastes, try to spread out the adhesive evenly to make a thin layer of adhesive under the surface of your dentures.
Use your clean and dry finger to do the distribution of the cream. But if you are using powder form, sprinkle the adhesive to the entire undersurface and shake off to distribute the powder as evenly as possible - Step 5:
immerse your dentures in cold water for around 30 second. This is to wet the adhesive completely on the dentures, which makes an excellent bond when dentures are seated on your gum
- Step 6:
place the dentures in your mouth and put pressure on them for a few seconds. If any excessive adhesive oozes out, trim away the extra adhesive
- An important tip:
avoid eating or drinking hot foods and drinks immediately after placement of dentures for around 15 minutes to allow a strong bond.
