A denture is a removable replacement for missing teeth and adjacent tissues. It is made of acrylic resin, sometimes in combination with various metals. Complete dentures replace all the teeth, while a partial denture fills in the spaces created by missing teeth and prevents other teeth from changing position. Complete dentures are either "conventional" or "immediate." A conventional denture is placed in the mouth about a month after all the teeth are removed to allow for proper healing, whereas an immediate denture is placed as soon as the teeth are removed. The drawback behind an immediate denture is that it may require more adjustments after the healing has taken place.

Candidates for complete dentures have lost most or all of their teeth. A partial denture is suitable for those who have some natural teeth remaining.
