A crown is a tooth shaped structure that is made to fit over an existing tooth structure.  We use tooth-colored crowns that are custom made to match the shade of your surrounding teeth.  They will blend perfectly with your other teeth and are strong enough to help you maintain your bite and chewing power.  Crowns are used when there is not enough tooth structure to hold a filling.  A broken tooth, a tooth that has been significantly compromised by decay and a tooth that has undergone root canal therapy are just some reasons that may indicate a crown is needed.
