Where a tooth is badly broken down, and is incapable of being restored in traditional methods e.g. restoration by filling – dental crowns may be the best option.
Crowns are usually required when your tooth has cracked or decayed and there is not enough support left to hold a filling in place. In this case, your dentist may fit a crown over the top of the existing tooth, retaining the remains of the tooth yet at the same time providing an outer barrier against bacteria.
