A crown is a dental appliance that replaces and covers the entire
part of a tooth above the gum line. A crown may be made of gold, porcelain, or
a combination of other man-made materials.
Crowns are used to:
- Repair teeth that have broken or decayed so
much that they can no longer be treated with a filling.
- Improve the
appearance of front permanent teeth (incisors) that are properly spaced but are
rotated and look crooked.
Crowns may be applied after a root canal treatment to seal the
tooth and prevent it from breaking.
