More Than a Filling. Less Than a Crown.
Inlays and Onlays in Thornhill
When a tooth is too damaged for a filling but does not require the full coverage of a crown, an inlay or onlay is often the ideal solution. These precision restorations are custom-crafted in a dental lab from high-quality materials, designed to fit the exact dimensions of the damaged portion of your tooth, and bonded in place for a result that is durable, beautiful, and conservative of your natural tooth structure.
What Is the Difference?
An inlay fits within the cusps of the tooth, restoring the center of the chewing surface. An onlay extends beyond the cusps, covering one or more of the raised points of the tooth, and is sometimes referred to as a partial crown. Both are fabricated from porcelain or composite resin materials that closely match the natural color of your teeth, making them virtually invisible once placed.
Why Choose an Inlay or Onlay?
They preserve more natural tooth structure than a crown. They fit more precisely than a traditional filling. They are stronger and longer-lasting than direct composite restorations for larger areas of damage. They are custom-made to fit your tooth perfectly. And because they are fabricated in a lab rather than placed directly in the mouth, the final result is exceptionally precise and durable.
The Process
Inlays and onlays require two appointments. At the first, we prepare the tooth and take detailed impressions that are sent to a dental lab. A temporary restoration protects the tooth in the meantime. At the second appointment, the custom restoration is bonded into place, adjusted to your bite, and polished to a smooth finish.

Common Questions
Frequently Asked Questions
How are inlays and onlays different from fillings?
A filling is placed directly into the tooth in one appointment and is shaped chairside. An inlay or onlay is fabricated in a dental lab from your precise impressions and then bonded into place. This makes inlays and onlays more precise, stronger, and better suited for larger restorations where a direct filling would not provide sufficient durability.
How long do they last?
With good oral hygiene and regular dental visits, inlays and onlays can last 10 to 30 years, making them one of the most durable restorative options available.
Are they covered by insurance?
Coverage varies by plan. Inlays and onlays are often covered under restorative benefits, though your plan may classify them differently from fillings or crowns. We will help you understand what is covered before treatment begins.
