Dental Onlays in Beverly Hills and Northridge

When a tooth has sustained moderate damage or decay that is too extensive for a filling but does not require a full crown, a dental onlay is often the ideal solution. At Beverly Wilshire Dental Group in Beverly Hills and Northridge, CA, Dr. Mehryar Ebrahimi uses custom-fabricated porcelain onlays to restore the strength and appearance of damaged teeth while preserving as much healthy tooth structure as possible.

What Is a Dental Onlay?

A dental onlay — sometimes called a partial crown or an indirect filling — is a custom-made restoration that covers one or more of the cusps of a back tooth. It is fabricated outside the mouth in a dental laboratory from porcelain, composite resin, or gold, then bonded permanently to the tooth.

Onlays sit between a filling and a full crown in terms of the coverage they provide. A filling restores a small cavity within the tooth. A crown caps the entire tooth. An onlay covers a larger area than a filling — including one or more cusps — but leaves more healthy tooth structure intact than a full crown would require.

Inlays, Onlays, and Crowns — What Is the Difference?

Dr. Ebrahimi always recommends the most conservative restoration that can achieve a durable, lasting result. When an onlay can do the job, it is preferred over a full crown because it removes less healthy tooth structure.

The Dental Onlay Process

Step 1 — Preparation

The damaged or decayed portion of the tooth is carefully removed under local anesthesia. The tooth is shaped to receive the onlay, and precise impressions are taken. A temporary restoration is placed to protect the tooth while your custom onlay is fabricated by a dental laboratory — typically one to two weeks.

Step 2 — Fabrication

Your onlay is crafted from high-quality porcelain matched to the shade of your surrounding teeth. Porcelain onlays are strong, durable, and virtually indistinguishable from natural tooth enamel.

Step 3 — Bonding

When your onlay is ready, the temporary is removed and Dr. Ebrahimi checks the fit and appearance carefully before bonding the onlay permanently to the tooth. The result is a strong, seamless restoration that restores the tooth's full function and natural appearance.

Benefits of Porcelain Onlays

• Preserves more natural tooth structure than a full crown
• Custom-fabricated for a precise, comfortable fit
• Porcelain matches the color and appearance of natural teeth
• Stronger and longer-lasting than a large direct filling
• Bonds to the tooth, reinforcing its structural integrity
• Resistant to staining

How Long Do Dental Onlays Last?

With proper care, porcelain onlays typically last 10 to 15 years or longer — significantly more durable than large composite fillings in the same position. Regular professional cleanings, good daily oral hygiene, and avoiding habits such as biting hard objects or grinding teeth all help maximize the lifespan of your onlay.
