Dental health and dentures

When shouldn't denture adhesives be considered?

There are situations when denture adhesives should not be used. Those cases include:

1. When it is used as a "fix" for ill-fitting or poorly constructed dentures. If your dentures begin to feel loose, cause discomfort or cause sores to develop, contact your dentist as soon as possible.
2. When a dentist has not evaluated your dentures for a long time. Dentures rest on gum tissue and your jawbone, which shrink and deteriorate, respectively, over time. Therefore, the real problem might be a need for a denture adjustment or new dentures.
3. When oral hygiene practices cannot be sustained.
4. When adhesives have been used for a long time, especially when visits to the dentist are infrequent, and when the frequency and volume of the adhesive use increases. These developments may indicate the need for a denture adjustment or new dentures.
5. When any known allergy exists to the adhesive's ingredients.

How are denture adhesives applied?

Here are some tips to consider when applying denture adhesives:

• Use the minimum amount necessary to provide the maximum benefit. Apply less than you think you need, and then gradually increase the amount until you feel comfortable.
• Distribute the adhesive evenly on the tissue bearing surface of the denture.
• Apply or reapply when necessary to provide the desired effect.
• Always apply the adhesive to a thoroughly clean denture.
• Remember adhesives work best with a well fitting denture.

What are the types of denture adhesives?

1. Paste application. Apply this denture adhesive to a dry or preferably wet denture. Avoid placing adhesive close to the denture borders. If the adhesive oozes, use less of the product. For dentures on the upper jaw, apply three short strips of adhesive, or s series of small dots-along the ridge area and one down the centre. For dentures on the lower jaw, apply three short strips of adhesive-or s series of small dots-in the centre of the ridge area.

2. Powder application. Sprinkle a thin, uniform layer throughout the tissue bearing surface of the denture. Shake off excess powder and press the denture into place. Powders may be preferred over pastes because they are easier to clean off the denture and tissue. In addition, they don't have the same tendency as pastes do to "shim" (keep the denture away from the tissue).

Are denture adhesives safe?

Dental adhesives are safe as long as they are used as directed. If the denture is well fitting and the adhesive is only used to give added stability, there should be no ill effects. If adhesives are used excessively to fill voids for an ill-fitting denture, they can be harmful to the underlying soft and hard tissues. Occasionally, in these cases, inflammation of the soft tissues can result. In addition, because of its movement on the soft tissue and underlying bone, an ill-fitting denture can cause bone loss.
