What are inlays and onlays?
Inlays and onlays are particular types of fillings made of composite resin, porcelain, or gold says dentist in Chertsey. An inlay is custom-made to fit the prepared cavity, while an onlay covers the entire chewing surface of the tooth. The primary disadvantage of inlays and onlays is their higher cost relative to traditional composite and amalgam fillings.

What you should know
GOLD- gold doesn't discolor or stain the teeth and has a longer life expectancy than silver. It can be placed esthetically into upper back teeth where it doesn't show; however, it shouldn't be placed opposite porcelain, because porcelain tends to wear gold rapidly during chewing.
PORCELAIN- research shows that bonded porcelain inlays and onlays can equal the strength of natural teeth, making them particularly attractive choices when booth esthetics and strength are required. However, extra stress can fracture porcelain just as it can natural teeth.
COMPOSITE- although not as long lasting as gold or porcelain, composite resin inlays and onlays are an esthetic and less expensive option.
