What are Inlays and Onlays?

Inlays

Traditionally, inlays replace a small amount of tooth structure left by a cavity, just as fillings do. They filled and sealed the tooth but were made only of gold. Inlays today are made of tooth-colored material such as ceramic, porcelain, or a specialized dental composite.
The inlay consists of the tooth-colored material and bonding, a clear fluid material, to attach the inlay to the tooth. As explained by the American College of Prosthodontists, “Using a clear fluid version of this material to seal the exposed surfaces of the teeth decreases sensitivity to temperature changes and certain types of foods.” The bonding material is also tooth-colored and may help improve the color and appearance of stained or discolored teeth.

Onlays

Onlays are similar to inlays in that they fill a missing hole caused by a cavity, but onlays extend onto the chewing surface of a tooth to replace one or more cusps. Traditionally, they were also only made of gold, but tooth-colored onlays have made an appearance in dentistry. An onlay is considered a more effective option for patients with large cavities or the decayed area expands over the top of the tooth.

The process of inlays and onlays both involve bonding material to attach and seal it to the tooth. In both treatments, the bonding material may actually improve the strength of the tooth.

Glendale Dental Veneers and Laminates

If you are concerned about the appearance of your old fillings, new tooth-colored treatments can restore and transform your teeth. Silver and gold fillings are a thing of the past as cosmetic treatments such as inlays and onlays are a new and effective treatment. Inlays and onlays are similar to traditional fillings as they fit inside the tooth where a cavity once was and seal it. The signifying difference is that they come in a variety of tooth-colored materials for an enhanced, more uniform smile.

As most inlay and onlay treatments replace old fillings, the cavity has already been removed and filled. This makes treatment easier, faster, and generally pain-free. Inlays and onlays provide a more sustainable treatment and a natural-looking smile.

Inlays and onlays are available at Dental Design Studio in Glendale and the surrounding area. Our staff can help you determine whether this treatment is right for you.

Benefits of Inlays and Onlays

1. Inlays
The key benefits of inlays lie in their durability and strength. They are intended to protect and seal the tooth from further damage using cemented material custom-fit to each tooth. The sealed inlays also protect the tooth from air and food particles from entering the tooth, which causes a sensitive sensation. Before an inlay treatment, the dentist removes all bacteria from inside the tooth and throughout the hole, attaining a higher level of oral hygiene. Inlays are more stable and stay in your tooth for much longer than a filling with proper oral care.

2. Onlays
Onlays have many of the same benefits as inlays. An added benefit to onlays is they can save much of the patient’s tooth structure and provide additional strength and support for the affected tooth. Crowns require treatment and typically involve removing the entire tooth or, at minimum, much of the tooth structure. Onlays are also custom-fit for each patient and use stain-resistant material, making them last much longer without affecting appearance.
