Inlays and Onlays
When more than a third of a tooth's biting surface is damaged, a dentist will often use an inlay or onlay. Large fillings on back teeth often require a stronger and properly contoured restoration, such as porcelain inlays or onlays. They are created at an off-site dental lab and are bonded into place using a strong resin. Inlays and onlays protect teeth similarly as crowns, but conserve more natural tooth structure and are a better match to your tooth's natural color.
