When a tooth’s biting surface is compromised by more than half, a dentist will most likely employ an inlay or onlay.

What are the differences between inlays and onlays in dentistry?

Porcelain, gold, or composite resin can be used for inlays and onlays. These parts are attached to the tooth’s affected area. Inside the cusp points of the tooth, an inlay, which is similar to a dental filling, is applied. An onlay is a larger restoration that is comparable to an inlay but extends over one or more of the tooth’s cusps.

Gold has always been the preferred material for inlays and onlays. Porcelain, on the other hand, has grown in popularity in recent years as a result of its strength and color, which can potentially match the natural color of your teeth.

Inlays and onlays are used in a variety of ways

At Oral Health Center, the treatment for inlays and onlays takes two appointments to complete. The filling being replaced or the damaged or decayed part of the tooth is removed during the first session, and the tooth is prepared for the inlay or onlay. The dentist takes an impression of the tooth and sends it to a lab for manufacture to guarantee perfect fit and bite. The dentist will then apply a temporary sealant to the tooth and make an appointment for the following visit.

The temporary sealant is removed at the second appointment. Dr. Banga will then inspect the inlay or onlay for proper fit. The inlay or onlay will be cemented to the tooth using a strong resin and polished to a smooth finish if the fit is satisfactory.

Inlays and Onlays: What to Think About

Traditional fillings can weaken a natural tooth’s strength by up to 50%. Inlays and onlays, which are bonded directly to the tooth with particular high-strength resins, can actually boost a tooth’s strength by up to 75 percent. As a result, they can last anywhere between ten and thirty years. Onlays can be an excellent alternative to a full dental crown in some circumstances where the damage to the tooth isn’t severe enough to warrant one.
