Inlay and onlay restorations at Radiant Dentistry of Woburn

What Are Inlays and Onlays?

Inlays and onlays are custom-made restorations that fit inside or over the damaged part of a tooth. They are often called “partial crowns” because they cover less tooth than a full crown. Both are made of strong, tooth-colored porcelain that bonds directly to your natural enamel. The difference between them comes down to which part of the tooth they restore.

Inlays — Restoring the Inner Tooth Surface

An inlay fits within the grooves (the chewing surface) of a back tooth. It is used when the decay or damage is limited to the center of the tooth and does not extend to the pointed edges called cusps. Inlays work well for medium-sized cavities that are too large for a filling but still contained.

Onlays — When Damage Extends to the Cusps

An onlay covers one or more of the tooth’s cusps. If the damage reaches the outer edges, an onlay provides the extra protection needed without removing as much tooth structure as a crown. This makes onlays a strong, conservative choice for teeth with more extensive wear or decay.

Why Inlays and Onlays May Be Right for You

Inlays and onlays offer several benefits that make them a smart choice for many patients:

Tooth conservation: They require removing less healthy enamel than a crown, so your natural tooth stays stronger.
Durability: Porcelain inlays and onlays can last 10 to 15 years or longer with proper care.
Precise fit: Digital impressions (using our iTero scanner) create a perfect match to your tooth, reducing the chance of gaps or irritation.
Aesthetic match: The porcelain blends seamlessly with your surrounding teeth, so the restoration is nearly invisible.
Biocompatibility: Porcelain is gentle on your gums and does not cause the sensitivity some people experience with metal.

When a tooth has too much damage for an inlay or onlay, a dental crown may be the better option. Dr. Austria will discuss both choices with you and explain which one fits your situation.

What to Expect at Your Appointment

The process for getting an inlay or onlay usually takes two visits.

Your First Visit — Evaluation and Impressions

Dr. Austria will examine the tooth and take digital X-rays to see the extent of the damage. After numbing the area, he removes any decay and shapes the tooth. A digital scan is taken to create a precise model. You will leave with a temporary restoration while your custom inlay or onlay is made in a dental lab.

Placement Visit — Bonding and Final Fit

At your second visit, the temporary is removed and the new porcelain piece is checked for fit and color. Dr. Austria bonds it to your tooth using a special cement and polishes the surface so it feels smooth against your bite.

Frequently Asked Questions About Inlays and Onlays

Answers to your most common questions.

How long do inlays and onlays last?
With proper care, inlays and onlays can last 10 to 15 years or longer. They are made from durable porcelain that resists wear and staining. Regular brushing, flossing, and dental checkups help extend their lifespan.
Are inlays and onlays covered by dental insurance?
Most dental insurance plans cover inlays and onlays at a percentage similar to fillings or crowns. Coverage varies by plan, so we recommend checking with your provider. We accept most major insurance plans including Delta Dental, Blue Cross Blue Shield, and Altus Dental. For more details, visit our Insurance & Financing page.
Is the procedure painful?
No. We numb the area thoroughly with local anesthesia before any work begins. Most patients report little to no discomfort during the procedure. Afterward, any mild sensitivity usually fades within a few days.
Can an inlay or onlay replace an old metal filling?
Yes. Inlays and onlays are a great option for replacing worn or failing metal fillings. They bond directly to the tooth, which helps restore strength and seal the tooth against bacteria. They also match the natural color of your teeth. If you are considering a tooth-colored restoration and want to keep as much of your natural tooth as possible, Restorative & Specialty Care includes several options. We also offer tooth-colored fillings for smaller areas of decay. For more extensive wear, our dental crowns page explains how full coverage restorations work.
