Crowns and Bridges
What is a Crown or Bridge?
If you have teeth that are very badly broken down a crown could be the answer as it fits over the existing natural tooth to replace its natural crown. This natural crown is usually replaced with dental ceramic which is tooth coloured. In the case of a bridge it is used for replacing more than one missing tooth by anchoring the artificial teeth with crowns to the natural teeth. (As pictured on the left)
What is the process?
Tooth decay, a large filling, root canal treatment and just wear and tear over the years can all weaken a tooth. If a tooth requires a Crown or Bridge, it will take two appointments with the first one lasting more than an hour long and involves the tooth being prepared to make room for the porcelain crown and bridge, impressions will then be taken and sent to a dental laboratory. The second appointment will be approximately two weeks later so that the crown or bridge has had time to be custom made, an appointment for half an hour will be required so that it can be fitted correctly into position, adjusted for fit and comfort before being cemented and shaped to look and feel like a natural tooth.
CEREC is a computer milled ceramic that is also used to allow fabrication and insertion in one visit it can only be used for crowns. Bridges are made using a two stage procedure and are laboratory made.
Types of Crowns
- All porcelain (Zirconia) for aesthetic cases especially front teeth (Crowns and Bridges)
- CEREC crowns commonly used for most back teeth allowing a one visit procedure (for information on CEREC technology click here)
- Porcelain fused to Gold for some back and front teeth. It has higher strength and is used for selected patients (Crowns and Bridges)
- Full gold crown (high strength) for back teeth only (Crowns Only)
