A denture or complete denture is an appliance that is inserted in the mouth, replaces natural teeth and provides support for the cheeks and lips.
Most dentures are made of acrylic and can be fabricated two different ways. A conventional denture is made after all teeth have been extracted and the gum tissue has healed. An immediate denture is fabricated and inserted immediately after the teeth are extracted and the gum tissues are allowed to heal under the denture. An upper denture has acrylic; usually flesh colored that covers the roof of the mouth. A lower denture is shaped like a horseshoe to leave room for the tongue. The teeth are made of plastic, porcelain or a combination. Dentures can be fabricated to fit over endodontically treated teeth and a complete denture can be attached to implants to allow for a more secure fit of the appliance. Dentures over a normal course of time will wear and need to be replaced or relined in order to keep the jaw alignment normal. The alignment will slowly change as the bone and gum ridges recede or shrink due to the extraction of the teeth. Regular dental exams are still important so that the oral tissues can be checked for disease or change.
