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.
In such cases, a pediatric dentist is likely to recommend a stainless steel crown.
