A dental crown is a type of cap that covers the visible tooth and is cemented into place to provide a permanent fixture. Dental crowns are used to protect, strengthen, restore the shape and repair a tooth.

Crowns are used when a tooth has become weakened or cracked. They can hold together a broken tooth or reinforce a badly worn tooth. Crowns are sometimes used to support a tooth that has had a large filling installed and little natural tooth remains. 

A crown strengthens your existing, damaged tooth so as to preserve its functionality. Dental crowns are also commonly known as caps (because a crown sits over your existing tooth, covering the entire outer surface). 

Why you might need a crown?

  • If your tooth has undergone significant decay and there is not enough tooth structure remaining to support a filling or an inlay and maintain functionaility.
  • If a large portion of your tooth has fractured and it cannot be built up using traditional composite bonding techniques .
  • If you have a large cavity and opt for the additional protection a crown offers to your tooth over a large composite filling or an inlay.
  • If you have had a dental implant to replace a missing tooth, a crown will be fitted to the abutment of the titanium implant.
  • Following root canal treatment, a crown is often needed to strengthen the tooth.
  • If you grind your teeth and have a poor diet, acid erosion may reduce your teeth to a point where the only option available is to crown them.
  • For cosmetic reasons, to improve the aesthetics of your smile, you may opt for all porcelain cosmetic crowns.
