A crown (often called a cap) covers the entire tooth and restores it to its original shape and size. If a tooth is chipped or broken from an accident or badly decayed or root filled, a crown is often the best way to save the tooth and strengthen it.
Crowns are incredibly strong and are usually made of porcelain or gold alloy.
Porcelain is strong and can match the colour of natural teeth perfectly. It is resistant to all stains.
Gold alloy is used for its strength, hardness and durability. It is especially useful in molar teeth which must withstand the forces of grinding and crushing.
Whenever teeth are crowned, there is a risk that the underlying nerve may die and become infected. If this occurs, the tooth may need root canal treatment
