Inlays & Onlays

Inlays and onlays are custom-made restorations that repair damaged teeth when you need more than a filling but less than a crown. An inlay fits inside the tooth’s cusps (the pointed parts), while an onlay covers one or more cusps. Both are made from strong materials like porcelain or composite resin and are bonded to your tooth. They’re sometimes called “partial crowns” because they provide more coverage than fillings.

You might need an inlay or onlay when a cavity or crack is too large for a regular filling but your tooth is still too healthy for a crown. They’re perfect for medium-sized damage that requires more strength than a filling can provide. Inlays and onlays also work well for replacing old, large fillings that are failing or when you want a longer-lasting restoration than a traditional filling.

The procedure is comfortable because we use local anesthesia to numb the area completely. You might feel some pressure while Dr. Fenton removes the damaged tooth structure and shapes the tooth, but no pain. After treatment, you might have mild sensitivity for a few days as your tooth adjusts, but most patients find this minimal and easily managed with over-the-counter pain relievers.

The process typically takes two appointments over 2-3 weeks. At the first visit, Dr. Fenton removes the damaged portion of your tooth and takes impressions for your custom restoration. You’ll have a temporary filling while your inlay or onlay is made in our dental lab. At the second appointment, we remove the temporary and bond your permanent restoration in place.

Inlays and onlays typically last 10-20 years, often longer than traditional fillings. They’re made from strong materials and bonded to your tooth, making them very durable. Porcelain inlays and onlays resist staining and wear well over time. With good oral hygiene and regular checkups, many patients keep their inlays and onlays for decades without problems.

Caring for inlays and onlays is simple – just brush and floss like you would with natural teeth. Use fluoride toothpaste and floss daily, paying attention to the edges where the restoration meets your tooth. Avoid chewing ice or using your teeth as tools. Regular dental cleanings and checkups help ensure your restoration stays in good condition and catches any issues early.

Inlays and onlays typically cost $800-$1,500 per tooth, depending on the size and material used. While they cost more than regular fillings, they’re less expensive than crowns and often last much longer than traditional fillings. This makes them a good value for medium-sized restorations. The investment is worthwhile considering their durability and natural appearance.

Most dental insurance plans cover inlays and onlays at 50-80% when they’re medically necessary. Coverage is typically similar to crowns since they’re considered major restorative work. Some plans might have specific guidelines about when inlays and onlays are covered versus fillings or crowns. We’ll verify your benefits and help you understand your coverage before starting treatment.
