Onlays and inlays are used when an old filling needs replacing. An inlay sits within the tooth, whereas an onlay sits within the tooth but also extends over or replaces missing cusps.
Are onlays/ inlays better then filling?
They are stronger and can last longer than traditional fillings, and are especially suitable for the chewing surfaces on back teeth and large repairs to front teeth.
What are they made from?
Onlays and inlays are made in a dental laboratory and can be made from gold, porcelain or composite.
What is the difference between a crown and onlays/inlays?
A crown can return structure, strength, and function to a tooth with extensive decay or damage. Inlays and onlays are more conservative options replacing only what has been lost whilst retaining as much of the tooth structure as possible.
