When a tooth is too damaged for a simple filling but still has healthy structure worth saving, an onlay sits in the middle ground. It rebuilds the part that's gone without cutting the tooth down for a full crown.
Biomimetic dentistry means restoring a tooth so it looks and behaves like the original. A ceramic onlay is bonded to the remaining tooth structure and shaped to match your natural bite, using tooth-colored materials chosen for biocompatibility rather than metal. The goal is a strong, lasting repair that keeps more of your own tooth intact.
