Denture adhesives are usually used by the patient who just wants a little added security while eating and speaking. They are not recommended to be used when the replacement teeth are grossly ill-fitting. Dentists recommend that if they are to the point where they are moving about in the mouth, then perhaps it is time to make the appointment to have them readjusted through placement of a permanent liner or other measures.
Denture adhesives can come in a variety of different forms such as powders, pastes and strips. They are to be used sparingly once a day. Powders should cover lightly the moistened interior of the replacement teeth. Pastes should be put on in small dots around the interior of the moistened replacement teeth. The strips come prepackaged one at a time so they are to be placed in the interior of the moistened replacement teeth. It is important to remember that too little will result in little to no hold at all while too much, especially with the paste, will result in the product oozing over the side and making the patient gag.
Most of these are harmless, but denture adhesives that contain zinc can be problematic for patients if they are overused. If they are overused, the patient runs the risk of developing zinc toxicity which can have very negative results. For the best overall results, a patient should choose one that does not include zinc in its list of ingredients.
Denture adhesives are not recommended to be worn overnight because the device itself should be taken out and soaked. The reason for the soaking is to clean it and to give the gums underneath a rest. If the device is moving about, and this is the reason for the paste, then it may not be safe to sleep in it.
