A denture is an appliance that is inserted in the mouth to replace natural teeth. Dentures can be fitted to go over or around whatever viable teeth remain. There is an adjustment period for you and your new dentures after they are placed in the mouth. Often implants can be used to further stabilize the dentures if needed. Regular dental examinations are important for the denture wearer so that the oral tissues can be checked for any changes and continued function of the dentures.
