FILLINGS

Fillings are done to remove decay, and replace the affected tooth structure. It is called a filling because new material fills holes resulting from decay. Nowadays most teeth are treated with bonded tooth colored composite resin fillings. Caught early enough, cavities can be treated easily and painlessly. If not treated decay can lead to tooth pain and/or infection, and the tooth would need root canal treatment or extraction.

CROWNS

Crowns are full coverage restorations that are used to cover a tooth that is likely to break, or is too broken down to be restored with a filling. They are most commonly done after root canal treatment, or when a large filling wears out. The larger the hole made by a cavity that has to be treated, the more likely a crown will be needed. Even after a filling is put in a large cavity, a tooth is more likely to break. Keep in mind that the jaw muscles are the strongest in the human body. Teeth are subjected to tremendous pressures. Crowns ride over the weakened tooth, providing strength and protecting the tooth against breakage. A broken or cracked tooth is a far more serious matter and much more difficult to treat. Crowns prevent this, as well as making for a nice smile.

It takes two appointments to restore a tooth with a crown. In the first any decay is removed from the tooth and it is shaped to accept the crown. Then an impression is made of the tooth for use in fabricating a crown. Between the two visits the crown is made, most commonly of high-strength porcelain over a zirconia substructure, but can be made all metal. During this time a temporary crown is worn. In the second visit this temporary is removed. Then the permanent crown is adjusted as needed and then cemented in place.
