Inlays & Onlays

What are inlays and onlays?

Inlays and onlays can be made of porcelain, gold, or composite resin. These pieces are bonded to the damaged area of the tooth. An inlay, which is similar to a filling, is used inside the cusp tips of the tooth. An onlay is a more substantial reconstruction, similar to the inlay but extending out over one or more of the cusps of the tooth.

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

How are inlays and onlays applied?

Inlays and onlays require two appointments to complete the procedure. During the first visit, the filling being replaced or the damaged or decaying area of the tooth is removed, and the tooth is prepared for the inlay or onlay. To ensure proper fit and bite, an impression of the tooth is made by the dentist, and sent to a lab for fabrication. The dentist will then apply a temporary sealant on the tooth and schedule the next appointment.

At the second appointment, the temporary sealant is removed. Dr. To will then make sure that the inlay or onlay fits correctly. If the fit is satisfactory, the inlay or onlay will be 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. As an alternative, inlays and onlays, which are bonded directly onto the tooth using special high-strength resins, can actually increase the strength of a tooth by up to 75 percent. As a result, they can last from 10 to 30 years. In some cases, where the damage to the tooth is not extensive enough to merit an entire crown, onlays can provide a very good alternative.

INLAYS AND ONLAYS FAQ

How do I know if I need an inlay, onlay, or crown?
It depends on how much of the tooth is damaged. Our dentists will recommend the most conservative option that still protects your tooth.

Will my inlay or onlay look natural?
Yes! Porcelain inlays and onlays are custom-made to closely match the color of your natural teeth.

Can I eat normally after getting an inlay or onlay?
Yes. Once your restoration is bonded, you can return to eating normally, although avoiding very hard foods can help extend its lifespan.

Can an inlay or onlay be replaced if it becomes damaged?
Yes. Although they are very durable, inlays and onlays can be repaired or replaced if they become worn or damaged over time.
