It is a cap that covers over and protects a tooth that has serious decay and are cemented onto the surface of the teeth. Dental crowns will cover the entire visible aspect of a tooth hence becoming its new outer surface, restoring the tooth to the original shape. Crowns can be made of porcelain, zirconia, metal, or a combination.
Dental bridge is a special dental restoration technique for replacing missing teeth by fitting crowns on the adjacent teeth. An artificial tooth is fitted to connect between the crowns to bridge the gap.

A thorough examination and diagnosis will be done by our dentist to determine if a crown is needed. The dentist first examines the location, size of the defect, the way you bite and vitality of the affected tooth. If crowning is required, treatment consist of shade selection followed by careful removal of decayed and weakened areas of the tooth.
Our dentist will then administer a local anaesthetic to numb the area around the tooth. The tooth will be filed down and an impression will be taken so that a new crown can be fabricated to the exact specifications. A temporary crown is made and fitted over the prepared tooth in between visits.
On the fitting appointment, the temporary crown is removed and the permanent crown is cemented. Our dentist will check to ensure the crown can sit well, have good margins and is in contact with adjacent and opposing teeth.

If a tooth has part of its structure damaged by decay or fracture, crowns are the best treatment as they can restore teeth to their normal shape and size. If a tooth is cracked, the crown holds the tooth together. Veneers are thin porcelain coverings that are bonded onto the tooth exterior. Both crowns and veneers may be used for modifying colors or position of teeth. The gums around the teeth must be good health before crowns and veneer treatments. Crowns or veneers cannot treat gum problems. Consult a dentist to assess whether crowns or veneers are suitable for you and whether you need to address any existing gum problems.
