Inlays & Onlays

When more than half of a tooth’s biting surface is damaged, we often use an inlay or onlay to restore the tooth’s anatomy.

What are dental inlays and onlays?

Inlays and onlays are made of porcelain, gold, or composite resin and are bonded to the damaged area of the tooth. An inlay, which is similar to a dental filling, is placed inside the cusp tips of the tooth.

Traditionally, gold has been the material of choice for inlays and onlays. However, in recent years, porcelain has become increasingly popular due to its strength and color, which has the potential to match the natural color of your teeth.

How are inlays and onlays applied?

Two appointments are required for the completion of inlays and onlays.

First Appointment

During the first visit, the damaged or decaying area of the tooth (or the filling that is being replaced) is removed, and the tooth is prepared for the inlay or onlay. To ensure proper fit and bite, we make an impression of the tooth and send it to a lab for fabrication. Dr. Martin then applies a temporary sealant on the tooth and schedules the next appointment.

Second Appointment

At the second appointment, the temporary sealant is removed. Next, Dr. Martin make sure that the inlay or onlay fits correctly. If the fit is satisfactory, the inlay or onlay is bonded to the tooth with a strong resin and polished to a smooth finish.

Considerations for Inlays and Onlays

Traditional fillings can reduce the strength of a natural tooth by up to 50 percent. Alternatively, inlays and onlays, which are bonded directly onto the tooth using special high-strength resins, actually increase the tooth’s strength by up to 75 percent. As a result, they typically last from 10 to 30 years. In some cases, where the damage to the tooth is not extensive enough to warrant an entire dental crown, onlays provide a suitable alternative.

Dental Inlays and Onlays FAQs

Are dental inlays and onlays painful?

The procedure is generally comfortable, and local anesthesia is used to minimize discomfort during treatment. Some patients may experience mild tooth sensitivity afterward, but this typically improves within a few days.

How long do dental inlays and onlays last?

With proper care, dental inlays and onlays can last many years. Their lifespan depends on factors such as the material used, oral hygiene, bite forces, and habits like teeth grinding. Regular dental checkups and good oral hygiene can help extend the life of your restoration.

What is the difference between an inlay and an onlay?

An inlay fits within the grooves of a tooth without covering its outer cusps. An onlay covers one or more cusps and is used when a larger portion of the tooth needs to be restored. Your dentist can recommend the best option based on the extent of the damage.

Can I eat normally after getting an inlay or onlay?

Yes, you can generally return to your normal diet once your permanent restoration is placed. However, avoiding very hard or sticky foods and chewing on objects like ice can help prevent damage to your restoration. If you receive a temporary restoration, follow your dentist’s instructions about eating until the permanent one is placed.

Can a tooth with an inlay or onlay still develop cavities?

Yes. Although inlays and onlays restore damaged portions of a tooth, the surrounding natural tooth structure remains vulnerable to decay. Brushing twice daily, flossing regularly, and attending routine dental checkups and professional cleanings can help protect your restored tooth.

Does insurance cover dental inlays and onlays?

Many dental insurance plans provide at least partial coverage for inlays and onlays when they are considered necessary to restore a damaged or decayed tooth. Coverage varies by plan, including deductibles, annual maximums, and approved materials. Check with your insurance provider to confirm your benefits before treatment.
