A partial denture is a removable appliance that can replace missing teeth in the upper or lower jaw. A partial looks like a retainer and is made up of a metal and/or acrylic type material with the false teeth in the appropriate places. There are usually metal clasps on each side that slide over the teeth and help hold the partial in place.
A full denture is a removable appliance that replaces all the teeth on either the upper of lower jaw (or both). They are for people who have no teeth in one or both jaws. The patient must not sleep with the denture in place, as it will cause irritation to the gums. It should be brushed just like your normal teeth. A denture takes several visits to fabricate and like partials, may need to be adjusted after being made.
