What are Crowns and Bridges?

What are Crowns and Bridges? A crown, or a “cap,” fits over an existing tooth. It requires restoration due to deep decay, a fracture, or a crack. At least three units make up a bridge: two crowns (abutments) fused to a pontic, or fake tooth, that replaces a missing tooth.
If the tooth is damaged, but can still be used, a crown is probably best. If the tooth is missing or must be removed entirely, a bridge is probably best. But before you decide, you should talk to your dentist. Because he or she will know more about the condition of your teeth.
The main difference between a bridge and a crown is the way in which they function. A dental bridge fills in the space caused by one or more missing teeth, while a crown covers an existing tooth.
