Bridges are usually made by crowning the teeth on either side of the gap, then attaching a false tooth in the middle. They are fixed in the same way as crowns. These bridges are usually made of precious metal bonded to porcelain.
Occasionally, other non-precious metals are used in the base to give it extra strength. There are also new bridges made entirely of a special type of strong porcelain.
Metal bridges are stronger than porcelain
bonded bridges, which in turn are stronger than porcelain only bridges.
