A dental crown may be needed in the following situations:
To protect a weak tooth (for instance, from decay) from breaking or to hold together parts of a cracked tooth. To restore an already broken tooth or a tooth that has been severely worn down. To cover and support a tooth with a large filling when there isn’t a lot of tooth left. To hold a dental bridge in place. To cover misshapen or severely discolored teeth. To cover a dental implant. To make a cosmetic modification.
For young children crowns can be used on baby teeth in order to:
Save a tooth/teeth that have been severely damaged by decay that it cannot support a filling. It can also be used to protect the teeth of a child at high risk for tooth decay. Decrease the frequency of general anesthesia for children unable because of age, behavior, or medical history to fully cooperate with the requirements of proper dental care.
