What are New Style Dental Crowns?
Dental crowns are restorations that protect damaged, cracked or broken down teeth. 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).
Modern crowns can now be made without a metal substructure and these are very life-like and translucent. In the absence of a metal substructure they remain cosmetic for longer.
Why might I need crowns?
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.
What is involved?
Crowns require two visits: one for the preparation and one for the fitting, usually two weeks later. A temporary crown is made as an interim. These are high quality plastic materials and last well, usually without becoming detached and blend in well with the surrounding teeth.
Metal based crowns or even gold crowns may still be the treatment of choice where the bite is heavy or very close, particularly at the back of the mouth.
