A crown is sometimes known as a ‘cap’. Crowns are ideal restorations for teeth that have been broken or weakened by trauma or decay and the remaining tooth structure is not capable of supporting a regular filling. On occasion crowns are placed on teeth that are already heavily restored or root canal treated to prevent fracture in the future. They can be made of porcelain or metal or a combination of these materials.
The process of placing a crown requires at least two appointments. At the first appointment the tooth is prepared, moulds/records taken and the tooth will be protected with a temporary restoration. The moulds and records are sent to a dental lab and the finished restoration is returned to the dentist after approximately two weeks. At the fitting appointment the temporary is removed and the new restoration is checked before it is fitted.
After the final restoration is fitted it is extremely important to maintain good hygiene and attend for regular check-ups/hygiene visits to ensure it lasts as long as possible.
Inlays and onlays are two types of restorations that your dentist can suggest as an alternative to a full coverage crown if the tooth is deemed suitable for either restoration. Both these options require less tooth preparation than a conventional crown, however still require the same number of appointments and stages as a conventional crown. An inlay is a small filling that fits into the biting surface of a tooth while an onlay covers a larger area of the tooth and is better suited to bigger cavities.
Before the treatment is undertaken we will assess the tooth and take x-rays as required.
