In cases where the area of decay is too large to accept a traditional filling, or the tooth structure is too weak to support a composite filling, we recommend a porcelain inlay or onlay restoration. This procedure increases the stability of your tooth and is stronger than a regular filling. These restorations are made to either fill the area inside the tooth up to the cusps (inlay) or completely cover the cusps of the tooth (onlay) providing a durable porcelain restoration for previously damaged teeth.
