A crown is a cap that is permanently placed over your tooth. It’s designed to cover and protect it. A crown can strengthen a tooth that’s weak or damaged. It restores a decayed tooth’s appearance. It can be used to attach a bridge, or to cover a dental implant or a tooth that has been treated with a root canal.
Materials
Crowns are made from many materials. They can be metal, ceramic, porcelain, resin, or a combination of materials. They differ in price, appearance and durability.
Types
Some crowns cover the entire tooth. Others only cover part of your tooth, such as a broken cusp of a molar. This type of crown is called an “onlay.” An onlay is a good choice for a tooth that is damaged but is still strong.
Fitting
Getting a crown commonly requires two visits. At the first visit, the dentist makes a mold of your tooth, prepares your tooth, and fits you with a temporary crown. At your next visit, the temporary crown is removed and the permanent one is put in place.
If you have a discolored, decayed, or broken tooth, a crown can help restore your smile. Talk to your dentist to find out which type of crown may be right for you.
