Decayed or chipped teeth can often be repaired with white composite fillings that look natural, however if the damage is too substantial, particularly on the back teeth, then an inlay or onlay would be recommended. Inlays or onlays can be made from a number of strong materials such as metals or ceramics.
An inlay is a small filling that fits into the biting surface of a tooth. An onlay covers a larger area of the tooth and is better suited to bigger cavities. Gold was traditionally used for these types of restorations. However, in recent times hard-wearing tooth-coloured porcelain has become a more popular choice of material. This is a more aesthetic way to restore the teeth and creates a more natural-looking smile. Here is how they work:
Thanks to advances in digital technology (called CAD/CAM) porcelain inlays can be made at some dental practices using a special milling machine known as CEREC. This means you will need fewer visits to the dentist to have your tooth restored.
