In some situations, a traditional dental filling may not be suitable for your teeth. If you’ve experienced a moderate amount of decay, we may suggest a porcelain inlay or onlay. Porcelain inlays cover the biting surface of the tooth inside the cusps, while onlays extend over the cusps and exterior surface. These restorations are crafted of high-quality porcelain, and serve to strengthen the structural integrity of the tooth to be fixed. In many cases, teeth restored with inlays or onlays don’t require additional protection from a dental crown.
