A dental crown is a tooth-shaped "cap" that is placed over a tooth.
It covers the tooth in order to restore its shape and size, strength, and improve its appearance. The crowns fully encase the entire visible portion of a tooth that lies at and above the gum line.
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 misshapened or severely discolored teeth
To cover a dental implant
To make a cosmetic modification
For children, a crown may be used on primary teeth in order to:
- Save a tooth that has been so damaged by decay that it can't support a filling.
- Protect the teeth of a child at high risk for tooth decay, especially when a child has difficulty keeping up with daily oral hygiene.
- Decrease the frequency of sedation and general anesthesia for children unable because of age, behavior, or medical history to fully cooperate with the requirements of proper dental care.
