Complete dentures are replacement teeth for when all your natural teeth have been removed. It comes in two types. You can wear immediate complete dentures for a couple of months while you wait for your gum tissue to heal. After that, you can get conventional complete dentures.

Complete dentures can be either "conventional" or "immediate." Made after the teeth have been removed and the gum tissue has begun to heal, a conventional denture is ready for placement in the mouth about eight to 12 weeks after the teeth have been removed.

Unlike conventional dentures, immediate dentures are made in advance and can be positioned as soon as the teeth are removed. As a result, the wearer does not have to be without teeth during the healing period. However, bones and gums shrink over time, especially during the healing period following tooth removal. Therefore a disadvantage of immediate dentures compared with conventional dentures is that they require more adjustments to fit properly during the healing process and generally should only be considered a temporary solution until conventional dentures can be made.

Partial Dentures

A removable partial denture or bridge usually consists of replacement teeth attached to a pink or gum-colored plastic base, which is sometimes connected by metal framework that holds the denture in place in the mouth. Partial dentures are used when one or more natural teeth remain in the upper or lower jaw. A fixed bridge replaces one or more teeth by placing crowns on the teeth on either side of the space and attaching artificial teeth to them. This "bridge" is then cemented into place. Not only does a partial denture fill in the spaces created by missing teeth, it prevents other teeth from changing position. A precision partial denture is removable and has internal attachments rather than clasps that attach to the adjacent crowns. This is a more natural-looking appliance.

Are Dentures Worn 24 Hours a Day?

Your dentist or prosthodontist will instruct you as to how long to wear dentures and when to remove them. During the first several days after receiving your denture, you may be asked to wear it all the time, including while you sleep. Although this may be temporarily uncomfortable, it is the quickest way to identify the areas on the denture that may need adjustment. Once adjustments are made, you should remove dentures before going to bed. This allows gum tissues to rest and allows normal stimulation and cleansing by the tongue and saliva. The denture can be put back in the mouth in the morning.

Should I Use a Denture Adhesive?

A denture adhesive may be considered under the following circumstances:

• To enhance satisfaction with a properly constructed denture. Adhesives enhance retention, stability, bite force, and an individual's sense of security.
• To assist individuals with dry mouth conditions that lessen denture adherence, such as individuals taking cold medications, those with neurologic disabilities including strokes, and the elderly.
• To provide added stability and security for those who place unusual demands on facial muscles, such as public speakers or musicians.

When Shouldn't Denture Adhesives Be Considered?

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

• When it is used as a "fix" for ill-fitting or poorly constructed dentures. If dentures begin to feel loose, cause discomfort or cause sores to develop, contact your dentist as soon as possible.
• When a dentist has not evaluated dentures for a long time. Dentures rest on gum tissue and the jawbone, which shrink and deteriorate, respectively, over time. Therefore, the real problem might be a need for a denture adjustment or new dentures.
• When oral hygiene practices cannot be sustained.
• 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.
• When any known allergy exists to the adhesive's ingredients.
