A dental bridge is a permanent and realistic looking way of filling a gap between teeth that has been caused by one or more missing teeth.
A bridge is an appliance which holds one or more false teeth on it. Unlike a denture, it is permanently held in place by the teeth next to it. It is usually made of a precious metal base such as gold, with tooth-coloured porcelain bonded to any visible areas to make it look natural.
Often, the two neighbouring teeth (one on each side) will need to have crowns fixed onto them to strengthen them. The two crowns are then joined together by placing the false tooth between them and cementing them in place. This is known as a (three unit) fixed bridge.
Sometimes adhesive bridges can be constructed. These have a lot less impact on the neighbouring teeth because the latest bonding techniques are used to hold the false tooth in place. This is known as a Maryland Bridge.
