Inlays & Onlays

What Are Inlays and Onlays?

Inlays and onlays are custom-made restorations, usually porcelain, that are bonded into a damaged back tooth. They're sometimes called partial crowns.

• An inlay fits inside the grooves between the cusps (the raised points) of the tooth, like a precise puzzle piece.
• An onlay covers one or more cusps as well, protecting a tooth with more extensive damage.

When Are They the Right Choice?

An inlay or onlay may be recommended when:

• A cavity is too large for a regular filling to hold up well
• An old filling has broken or worn down
• A cusp is cracked or weakened
• Enough healthy tooth remains that a full crown isn't necessary

What to Expect

1. Preparing the tooth. After numbing, we remove decay or the old filling and shape the tooth.
2. Digital scan. We take a precise scan and place a temporary restoration to protect the tooth.
3. Crafting your restoration. Your inlay or onlay is made to match your tooth's shape and color.
4. Bonding. At your second visit, we check the fit and bite, then permanently bond it in place.

Filling vs. Onlay vs. Crown

A filling is best for small to moderate cavities. A crown covers the entire tooth and requires removing more of it. Inlays and onlays sit in between: they're stronger and longer-lasting than a large filling, while preserving more natural tooth than a crown.

Inlay and Onlay FAQs

How long do they last?

With good care, porcelain inlays and onlays often last 10 to 15 years or more.

Will it match my teeth?

Yes. Porcelain is shaded to blend with your natural tooth.

Is it covered by insurance?

Many plans cover inlays and onlays similarly to crowns. We'll confirm your benefits first.
