Inlay and Onlay
Depending on the extent of the repair needed sometimes the full top surface of the tooth is removed.
A Full Onlay is then produced to replace the biting surface.
 
Gold is generally the optimum material for broken teeth at the back of the mouth where appearance may not be a priority. Gold inlays & onlays are very strong and very rarely fracture. Zirconium, porcelain & resin Inlays & Onlays are all tooth coloured and are normally used for areas that may be seen when patients smile.
People who grind their teeth during the night and may have a misaligned bite as a result are usually recommended to select the Inlay/Onlay produced from Gold or Zirconium materials as an alternative to the more aesthetic porcelain and resin types. Gold & Zirconium Inlays/Onlays are very strong and very rarely fracture.
Patients may also find the custom-made nature of inlays and onlays significantly more effective than older methods of reconstruction, due to the comfortable and natural feel of the fixture.
The treatment has been found to provide more functional longevity than simple white/silver filling methods used to treat similar dental issues due to the method used by dental professionals to physically bond the Inlay/Onlay to the damaged tooth.
The fitting of Porcelain inlays and onlays could also have a lasting effect on the smile due to the limited possibility of discolouring compared with previously used direct one stage white fillings that can stain much more easily.
Cleaning concerns could be a thing of the past following the procedure due to the smooth finish provided by dentists carrying out the treatment. There is no need to be concerned about sharp edges affecting the tongue and patients can use simple yet effective methods such as brushing and flossing to keep their breath fresh and teeth gleaming.

Alternative solutions, such as white fillings, often shrink and can become misshapen during the fitting process, which could limit the effectiveness of the treatment. For example the contact between a large white filling and the neighboring teeth may be less than ideal and allow food to trap between the filling and the neighboring tooth and cause gum irritation or infection.However, the precise fit of inlays and onlays ensures that patients can enjoy the benefits of the procedure with only two visits to the dentist.
As Inlays and Onlays are made indirectly in the laboratory and outside the mouth, the laboratory technician has a chance to shape and polish these restorations to their ideal shape and polish and also cure them completely so that no further shrinkage happens once they are fitted to the tooth.
Patients worried about the pain of the procedure arereassured to hear that local anesthetic is used throughout the treatment. Following the completion of the treatment, any temporary sensitivity can usually be resolved using over-the-counter painkillers.
The cost of the Inlays and Onlays differs based on the size of the restoration and the material used. Patients opting for porcelain fixtures created by more skilled technicians may be expected to pay more for the best possible cosmetic results.
Inlays & Onlays generally cost more than white fillings but on average they do last longer than white fillings and so in the long term may be more cost effective and involve fewer visits to the dentist.
