Teeth that are severely broken or decayed can be restored by removal of the decay, tooth preparation, and coverage with a crown. Some other indications for a crown are:
- A previously filled tooth in which more filling than tooth remains. The existing tooth structure has been weakened and can no longer support the filling.
- Discolorations or compromised esthetics
- Cusp fractures
- Abutments (supports) for a bridge
- After a root canal filling because teeth are structurally weaker; they tend to dry out and become brittle and are more apt to fracture.
Depending on the diagnosis, treatment plan, and discussion with the patient, teeth that are missing can be replaced with several options. They include the following:
- Fixed bridge
- Partial denture
