A crown is a cap fitted over a damaged tooth to restore its function and appearance, usually made from tooth coloured porcelain.
A bridge is used to replace a missing tooth and it bridges the gap between the adjacent teeth, fusing one or more false teeth to crowns that are fixed to either side of the gap. Bridges are made of porcelain and provide good eating function, look natural and maintain the integrity of the dental arch; they are also durable and resist stains.
To make a crown an impression of the tooth is taken to make a model which the dental technician at Harley Street Dental and Implant Clinic works off to create the right shape, which may take a few weeks, during which time the patient is fitted with a temporary crown. The permanent crown is fitted with a special adhesive designed to make it last 10 to 20 years with proper care and is matched to fit the natural colour of the patient’s teeth.
A crown can cover and support a tooth with a large filling when there isn’t enough tooth left, and can be used to attach a bridge or protect a weak tooth from breaking. It’s a good solution for teeth that are discoloured or badly shaped, or after a root canal treatment when teeth can become brittle as a result of losing nerves and blood supply.
Fixed bridges cannot be taken out of the mouth and look and feel like natural teeth.
If you have noticeably damaged or painful teeth, book a consultation with a dentist at Harley Street Dental and Implant Clinic to discuss whether crowns or bridges are suitable for you.
