The external surface of a tooth is made of strong enamel, but teeth can chip, break or weaken due to:
- Trauma – i.e. a knock or a fall
- Dental decay
- Root canal treatment
- Large amalgam fillings
- Age-related wear and tear
A crown or ‘cap’ is often the best way to save and strengthen a tooth. It fits over your existing tooth and can replace both front and back teeth.
A bridge replaces one or more missing teeth. An artificial tooth is attached to the adjacent natural teeth.
Crowns and bridges are made from porcelain, metal alloy or both. Porcelain is commonly used because it is strong and can be made to match the colour of the natural adjacent teeth. Both crowns and bridges can be produced on-site or by an external lab, depending on the case.
Our dentists use CAD/CAM (computer-aided design and computer-aided manufacturing) software to design and create the crowns for most patients. Teeth can be restored in a single appointment. We invite you to enjoy a complimentary tea or coffee while the crown is prepared on-site using the Cerec® milling unit. If you would like to view the process, please ask one of our friendly reception staff members.
The crown procedure is performed under local anaesthetic. It is about two millimetres thick, so the dentist first shaves this same amount from the tooth to avoid awkward-looking, over-sized teeth. He or she will also remove any decay before placing the crown. Our dentists use a CAD/CAM camera to electronically capture and store photographic images of the prepared tooth. The data is used to craft a virtual 3D design of the new tooth. The information is sent to a machine which uses specially designed diamond burs to mill the restoration from a ceramic block into a pre-determined shade matching the former or adjacent teeth. It is then polished, fitted and cemented into place.
With good oral hygiene and regular active maintenance, crowns and bridges can last many years. Speak with one of our friendly hygienists about how to achieve longevity from the new crown or bridge.
