Like a bridge, partial dentures rest on surrounding teeth to fill in the gaps where one or more teeth are missing. Unlike a bridge, partial dentures are fully removable. Partials are affordable alternatives to bridges and implants. It takes some time to adapt to new partials, but many patients regain much of their original function and esthetics with them in place. Partials are fabricated with replacement teeth attached to plastic base, or a combination of metal and a plastic base.
