A crown is a tooth-like restoration placed over a carefully prepared existing tooth or implant. Crowns serve many functions – to strengthen, restore or improve the appearance of natural teeth. Crooked, broken and dental trauma can all be addressed with crowns.
A healthy smile is one of the best ways to improve your confidence. At our practice, the primary focus is restoring dental health and beauty. Crowns are one of the solutions that can be used to create a stunning and healthy smile.
A crown can support the tooth when there is no longer sufficient tooth structure left to place a filling. Crowns may also be used to protect the structure of a tooth that is fractured or broken, and can be attached to bridges or implants to support dentures.
There are many different types of crowns, including those where the outer porcelain layer is fused to a metal sub-frame (porcelain fused to metal crowns) and those where there is no metal whatsoever (all porcelain crowns). Crowns can also be made using gold alloys.
Typically, crown treatment would involve:
• The administering of a local anaesthetic.
• The shaping of the tooth to accept the crown, or the insertion of a post to support the prosthetic. This involves the removal of any decay which may be present or filling compounds. The larger the nub of tooth that extends into the crown, the better.
• Sometimes it will be necessary to build up the tooth with filling material before it is suitable to attach the crown.
• All crowns must possess a certain minimal thickness so that adequate strength can be secured. For most types it’s about 2mm.
• An impression is taken to ensure a harmonious crown fitting.
• A temporary crown is then attached while the prosthetic attachment is made by a laboratory.
• A final appointment is needed for the fitting of the crown when it is
bonded into position.
Dental bridges literally bridge the gap created by one or more missing teeth.
The bridgework consists of two crowns either end of the bridge and a false tooth or teeth fixed between them.
The anchoring points are known as abutment teeth, similar in design to a normal single crown, and teeth between them are called pontics. The bridge is supported by the patient’s natural teeth which have to be ground down to accept the abutment teeth. The procedure offers an alternative to dental implants or dentures and can have good, predictable outcomes. Bridges can be manufactured from gold, alloys, porcelain, or a combination of these materials.
It is possible a more viable, long-term solution could be achieved using implant procedures and if this is a clinical preference our dentists will advise you.
