When a tooth is too damaged for a regular filling but not damaged enough to require a full crown, an onlay restoration provides the perfect solution. Sometimes referred to as a partial crown, an onlay is a custom-made restoration designed to strengthen and protect a tooth while conserving as much natural structure as possible.

At Peak Dental Utah, we create custom onlays made from porcelain, composite resin, or gold to match your natural teeth beautifully and deliver long-lasting results.

What Is an Onlay Restoration?

An onlay is similar to an inlay, but it extends over one or more of the tooth’s chewing cusps. This allows the onlay to restore a larger portion of a damaged tooth without the need for a full crown.

Each onlay is crafted in a professional dental laboratory and permanently bonded to your tooth for a precise, durable fit. Onlays are ideal for restoring teeth with significant decay, large fillings, or fractures, offering strength, stability, and an enhanced appearance.

Why Choose an Onlay?

Onlays are one of the most conservative restorative options available. They protect the tooth’s structure while avoiding unnecessary reduction of healthy enamel — something full crowns often require.

Common reasons for an onlay restoration include:
• Broken or fractured teeth
• Large or failing fillings
• Tooth decay or damage
• Cosmetic enhancement
• Restoring teeth after trauma

Onlays are highly durable and can last many years with proper care, helping you maintain a strong, natural-looking smile.

The Onlay Procedure: What to Expect

Getting an onlay typically takes two visits to complete:

First Appointment

• The affected tooth is numbed and cleaned of any decay or old filling material.

• The dentist reshapes the area to prepare it for a precise fit.

• An impression (digital or traditional) is taken and sent to a dental lab to fabricate your custom onlay.

• A temporary restoration is placed to protect your tooth while the onlay is being made.

Second Appointment

• The temporary is removed, and your new onlay is carefully fitted and bonded in place with permanent dental cement.

• Your dentist will check your bite and make small adjustments for comfort and accuracy.

Once the procedure is complete, you’ll leave with a tooth that looks natural, feels strong, and functions perfectly.

Caring for Your New Onlay

Good oral hygiene and regular dental visits will help extend the life of your onlay. Brush twice a day, floss daily, and avoid chewing excessively hard foods or ice. With proper care, onlays can last 10–20 years or longer.
