Bridges are also a permanent restoration. Normally the teeth either side of the gap are prepared by removing about 2mm of tooth to form a cone shape. Three crowns are then made from porcelain and gold. These are all joined together and cemented over the teeth either side of the gap – just like a bridge, that’s how they get their name. These are not taken out and are fixed in your mouth. Bridges require special cleaning and normally last about 10 years before they may need replacing.
Bridges are made of metal and porcelain or sometimes just porcelain. There are different types of bridge which use different fixing methods. Your dentist will choose the most effective and conservative bridge for your personal situation.
