About inlays & onlays
There are times when a tooth suffers damage (from decay, for example) that is too extensive to be treated with a simple filling — but not extensive enough to need a full-coverage crown. In these cases, the best option for restoring the tooth may be an inlay or onlay.
•Restorations to repair teeth with mild to moderate tooth decay.
•Used to repair cracked and fractured tooth if the damage is not severe enough to require a crown.
•Made from tooth-coloured porcelain.
•Often used to replace metal fillings for patients who desire a more natural looking smile. They differ from standard fillings in that they are a two stage process which involves a dental laboratory.
White composite filings and inlays and onlays are a bit different.
Inlays and onlays are larger filings that are made in the dental laboratory using porcelain instead of composite material. An inlay replaces the central chewing surface of a back tooth, but an onlay will replace a larger area which includes the central chewing area plus one or more of the cusps.
They also differ in that inlays are a two stage process which involves a dental laboratory, whilst fillings are placed in one appointment.
These inlays and onlays are made from a tough, ceramic material which resembles the natural colour of your own teeth and is extremely attractive to view.
Many patients choose Empress ceramic inlays as a replacement for their amalgam fillings. There is no risk of the inlays becoming discoloured over time. They are easy to clean as part of a daily dental routine and provide extra support for a tooth.

There are two stages to this process which differs from a normal filling which is carried out as a single procedure. This procedure is generally performed under a local anaesthetic. The process normally involves two visits, the first to prepare the tooth and the second to fit the custom made inlay.
- The first stage is the creation of a mould taken from an impression of your damaged tooth which is used as a guide for a cast. The cast is used to produce the inlays or onlays.
- The second stage is the fitting of the inlay or onlay. The dentist will check the fitting before securing it in place with dental cement. This ensures that it remains in place. She or he will then check the colour before giving it a final clean and polish. Your dentist will also check your bite.
