A denture is a removable replacement for missing teeth and adjacent tissues. It is made of acrylic resin, sometimes in combination with a metal framework. A complete denture replaces all the teeth in a jaw, while a partial denture fills in the spaces created by missing teeth and prevents other teeth from changing position. 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. A denture improves chewing ability and speech, and provides support for facial muscles. It will greatly enhance the facial appearance and smile. Both partials and full dentures are considered “removable” tooth replacement options in that they are designed to be removed from the mouth for cleaning purposes and at night to allow gum tissue to rest. Full dentures rely on suction with your gums and the roof of your mouth. Partials are retained in the mouth by gripping to your natural teeth with metal clasps or with devices called precision attachments. Use of denture creams should not be required if the denture is fitting properly. Over time a full denture or partial may have to be adjusted periodically in order to maintain retention within the mouth.
