Porcelain inlays and onlays
Inlays or onlays offer great protection for teeth that are at risk of breaking. As these teeth do not require a crown, less preparation of the teeth is involved which is healthier.

What is the difference between an inlay and an onlay?An inlay covers only one or two surfaces of the tooth and is used to restore an area with a small amount of decay. An onlay, on the other hand, actually covers one or more cusps (the chewing surface of the tooth) and is stronger, better protection for the tooth.
How are inlays and onlays made?Decay is removed and cleaned from the tooth and an accurate impression is made of the prepared tooth. This is used to fabricate a porcelain (tooth coloured) restoration called an inlay or onlay. The inlay or onlay is then bonded into the prepared surface of the tooth for maximum strength. The porcelain used perfectly matches the colour and shape of your teeth, is durable, strong, and virtually undetectable.
Why are inlays and onlays so effective?Inlays and onlays require the removal of only decayed areas of the tooth and minimal shaping to protect weakened areas, leaving the healthy tooth structure intact. Therefore, much more of the tooth structure can be preserved.
