Dental crowns are used to restore damaged teeth. A porcelain crown can be color-matched to your other teeth so the restoration is not obvious. If your tooth has been cracked, broken, or has received root canal treatment, you might require a dental crown.
Uses for Dental Crowns
Dental crowns cover the entire visible surface of the tooth, providing structure and strength to teeth that have been damaged or that have undergone root canal treatment. Common restoration issues treated with crowns include:
- Cracked teeth
- Teeth that have broken off
- Teeth that have already been filled but are suffering from additional decay
- Teeth with large fillings that have led to cracks
When a tooth receives root canal therapy, the internal tissues, called the pulp, are removed, leaving the tooth hollow. Although the dentist will fill the hollow area with a special resin, the tooth still isn’t as strong as it was before treatment. A crown helps keep the tooth intact and also adds strength and durability.
How is a Crown Placed?
Crowns are usually placed on the tooth in two stages. First, the tooth is prepared, which involves removing some enamel to make room for the crown. Your dentist takes a mold to ensure your new crown will fit perfectly. This mold is then sent to an off-site laboratory. You’ll wear a temporary crown for a few days, then when the permanent crown arrives, it is attached to your tooth with a powerful, permanent adhesive.
You can choose a porcelain crown, a metal crown, or a porcelain-bonded crown. The type you decide to have put on your tooth depends upon where the tooth is in your mouth as well as your personal preference and that of your dentist. Metal crowns are often preferred for back teeth, which must stand up to the extreme pressures of chewing. Front teeth are usually good candidates for porcelain crowns so the crown blends in with your natural teeth. Bonded porcelain can go in either position.
