What exactly is a cusp?+
It is one of the raised points on the chewing surface of a back tooth. Most molars have several, and they fit against the opposing teeth when you close.
Can a cusp break off on its own?+
A cusp weakened by decay, a crack or a large older repair can give way during ordinary chewing. If one has come off, call the clinic and describe what happened.
How many cusps can an onlay cover?+
It can extend over one or more of them, depending on which have been weakened. If so much of the tooth needs protection that an onlay no longer makes sense, a crown may be discussed.
Are inlays used on front teeth, which have no cusps?+
These restorations are generally for selected back teeth. A front tooth has a different shape and job, so the dentist would talk about what suits it instead.
Will my restored tooth still have peaks?+
Yes. The piece is shaped to restore a working chewing surface and is checked against your bite before being bonded.
