Very often dental bridges are used to replace several missing teeth. A bridge is a fixed partial denture used to replace one or several missing teeth in one spot, using false teeth stuck together to literally ‘bridge’ the gap left behind. Old-style bridges demand the paring down of healthy adjacent teeth, so if you have 3 missing teeth, you’ll also lose normal function of the two healthy teeth on either side of the gap in order to fit the bridge.
Using dental implants to support a bridge means prosthetic teeth can be supported from underneath, leaving healthy neighbouring teeth intact.
This is one of the main reasons why dentists prefer to use dental implants over dental bridges, implants can maintain healthy to structure either side of the gap.
