Dentures are removable replacements for missing teeth. Based on the individual patient, they may receive full or partial dentures. Full dentures come in two types and are meant to replace all of the natural teeth that have been removed from the mouth. Partial dentures are meant to replace some of the natural teeth that are missing in the mouth. If you lost your teeth a long time ago and have a full denture which has become loose over time, talk to Dr. Han to see if you are a candidate for implant overdenture.
