Bridges can be made out of the same materials as crowns and can be divided into two main categories. Adhesive bridges and crown based bridges.
Adhesive bridges require very little drilling of the supporting tooth. When the bridge eventually needs replacement the supporting tooth has not be damaged and can be used again. Adhesive bridges are more commonly used to replace front teeth where the chewing forces are less.
Crown based bridges require reducing the size of the teeth on each side of the space in a similar way to that required for crowns. The bridge is then cemented the prepared teeth. These bridges work very as they are very strong and can be used anywhere in the mouth where there are strong enough supporting teeth.
