Inlays & Onlays

 

There are times when the damage done to a tooth by decay is too extensive to be treated with a simple filling, yet not significant enough to need a full-coverage crown. In these cases, the best option for restoring the tooth may be an inlay or onlay.

Inlay and Onlay.

Both inlays and onlays are considered “indirect” fillings, meaning that they are fabricated outside the mouth (usually by a dental laboratory) and then bonded to the tooth by the dentist. This is in contrast to a “direct” filling, which is applied directly to the cavity by the dentist in one office visit.

An indirect filling is considered an “inlay” when it fits within the little points or “cusps” of a back (premolar or molar) tooth. It is an “onlay” if it covers one or more of these cusps. Either way, the procedure for placing an inlay or onlay is the same.

How It Works

Getting an inlay or onlay is very much like what you would experience having a crown placed, with one important distinction: less of your natural tooth structure will need to be removed by drilling in preparation to receive an inlay or onlay. When you get a crown, the tooth needs to undergo significant reshaping so that it will fit inside its new covering. Since our goal is to preserve as much of your natural tooth structure as possible, we often recommend inlays and onlays instead of crowns when a tooth can be restored with this more conservative type of treatment.

The first step in getting an inlay or onlay, then, will be to numb the tooth and surrounding area with a local anesthetic and then remove the decay. We have to do this in order to prevent the decay, which is actually a type of infection, from progressing deeper into the tooth.

Once we have finished preparing your tooth, we will take an impression of it, either digitally or with a putty-like material, and send it to the dental laboratory. There, the impression will be used to make a model of your tooth for the creation of your inlay/onlay. The final restoration can be made out of gold or a tooth-colored ceramic or resin. We can discuss these options in detail with you.

Before you leave the office, we will attach a temporary filling to your tooth to protect it until the permanent restoration is ready. At the second visit, your permanent inlay/onlay will be attached to your tooth with either a resin that hardens when exposed to a special light source, or a type of permanent cement.

Inlays and onlays are strong, long-lasting, and require no greater level of care than any other tooth. Conscientious daily brushing and flossing, and regular professional cleanings here at the dental office is really all you need to make sure your restoration lasts for years to come.
