Onlay Filling

A type of "indirect" restoration (made in a lab/mill) that covers one or more cusps (points) of a tooth but not the entire tooth. It is often called a "partial crown."

Why It Matters

When a cavity is too big for a regular filling but the tooth is not damaged enough to require a full crown, an onlay is the conservative choice. It preserves more healthy natural tooth structure than a crown.

Clinical Details

• Material: E-Max (Lithium Disilicate), Zirconia, or Gold.
• Strength: Restores 98% of the tooth's original strength.
