A crown, also known as a cap, is a permanent, protective covering for a tooth. It is used when a tooth has been weakened or extensively decayed and is used to help prevent further breakdown.
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 crown, when cemented into place, fully encases the entire visible portion of a tooth that lies at and above the gum line. A crown is a wonderful option for when you need your natural tooth to be restored to its original size, shape, and function. A crown is generally recommended to treat a previous tooth repair.
Why do I need a dental crown?
- To protect a weak tooth
- To restore an already broken tooth
- To cover and support a tooth with a large filling
- To hold a dental bridge in place
- To cover misshaped or severely discolored teeth
- To cover a dental implant
Permanent crowns can be made from stainless steel, all metal (such as gold or another alloy), porcelain-fused-to-metal, all resin, or all ceramic.
Temporary crown versus permanent crowns
- Temporary crowns are usually made in your dentist’s office from an acrylic-based material.
- Permanent crowns are typically made in a dental laboratory.
The average lifespan for a well-maintained dental crown is typically around 15 years. However, when taken care of properly, it is common to see them last upwards of 25-30 years
