A fixed bridge replaces one or more missing natural teeth.
It cannot be removed (except by your dentist). It is cemented into place and is firmly attached to the natural teeth that are next to the space. These teeth are called the abutment teeth.
Crowns are placed on the abutment teeth to provide support for the fixed bridge . The pontic, or the artificial tooth, is that part of the bridge that replaces the lost tooth. The pontic is fused to the abutment teeth, making one complete unit!
