A dental crown is a tooth-shaped "cap" that is placed over a tooth -- to cover the tooth to restore its shape and size, strength, and improve its appearance.
The crowns, when cemented into place, fully encase the entire visible portion of a tooth that lies at and above the gum line.
Why Is a Dental Crown Needed?
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 misshapened or severely discolored teeth
• To cover a dental implant
• To make a cosmetic modification
For children, a crown may be used on primary (baby) 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.
