Inlays / Onlays
Somewhere between fillings and crowns are dental inlays or onlays. These are used when not enough tooth structure remains to support a filling but the tooth is not so severely damaged that it needs a crown. Similar to a filling, an inlay lies within the cusps, or bumps, of the chewing surface of your tooth. An onlay, on the other hand, is more extensive and covers one of more cusps.
