Dental inlays and onlays are partial restorations of teeth. They are used to repair back teeth where there is a fracture or mild or moderate decay.
Inlays/Onlays are recommended for patients where too much decay or damage has occurred in the structure of the tooth for it to be possible to treat it successfully by using a normal filling.
But, the patient must still have an adequate amount of healthy tooth remaining not to need a crown.
An Inlay/Onlay lets your dentist save more of the structure from your original tooth
If an old filling has to be removed or replaced, then dental Inlays and onlays can also be used.
An inlay is like a filling. It fits inside the top edges (cusp tips) of a tooth.
An inlay is between a dental crown and a dental filling. Like dental inlays, onlays can restore large cavities without requiring a crown.
An onlay is more extensive than an inlay. It also prolongs over the tooth’s cusps which has been treated.
