Dental crowns are used in restorative dentistry to cover teeth affected by damage or decay. Once a cavity has been filled, the dentist will place a crown on top of the remaining tooth structure, preventing further decay from occurring and restoring the natural shape of the tooth.
Crowns are used to amend the shape, size, and strength of teeth, and can be used for both aesthetic and functional reasons.
Crowns are also commonly used to strengthen teeth following root canal therapy, as these teeth are more brittle and likely to fracture. They may also be used to repair the following oral conditions:
- Excessive grinding of teeth, or an improper bite
- An irritable large filling
- Inadequate oral hygiene
- Ageing teeth
