Crowns
Crowns become necessary when there is insufficient tooth structure to support a filling. Teeth that are severely broken down from decay or fracture can be fully restored to proper appearance and function with a crown on the tooth. A Partial crown (not requiring to cover the whole tooth) is called an Onlay.
Sometimes referred to as a cap, a crown is made from either ceramic or gold or other metal (or a combination) and shaped to mimic a natural tooth. It is actually fitted over the remaining part of your own tooth which means less removal of your original teeth, and a stronger, more natural looking result.
Reasons for needing a Crown or Onlay
- Root canal treated tooth
- Cracked/fractured tooth
- For weak/ brittle teeth
- Largely filled teeth
- Worn down teeth
A Crown/Onlay is prepared in 2 stages:
1
Stage 1
Preparation for the crown takes place at this appointment. The tooth is prepared for a crown to be fitted over the top of it and impressions are taken to be sent to the dental laboratory for the crown to be made. The insert appointment will be booked in for 2-3 weeks after this appointment to allow time for the crown to be made at the laboratory.
2
Stage 2
The insert occurs once the dentist has checked the crown in the mouth and the dentist and patient are happy with the overall look and function of the crown. If all is well the crown will then be cemented in place.
