Crowns are indicated for teeth when filling no longer suffice. Once the filling occupies more than 50 % of the tooth Crowns are needed which are often called “Caps”.
Main Reasons for crowns include:

- Your tooth is weakened due to intense grinding
- Your existing crown is failing

Crowns can be made from many different material which include:

Each material has its advantages and disadvantages. All Porcelain crowns are the latest in technology and becoming more popular because of their natural look.
Dental bridges do exactly what their name implies: bridge gaps left by one or multiple missing teeth. The two teeth on either side of the gap to be bridged serve as anchor teeth. Each anchor tooth has a crown that attaches to the false tooth/teeth of the bridge. Dental bridges can be supported by natural teeth with crowns on top, or by implant-supported crowns.
