Dental Inlays and Onlays
More conservative than a crown, inlays and onlays are two methods of restoring normal tooth structure after decay or other damage. Inlays and onlays are known as indirect fillings because unlike a standard filling that is done in a dentist's office, both are made in a laboratory and cemented or bonded to the surface of the tooth during a second visit to the dentist. And unlike standard fillings, inlays and onlays do not weaken the tooth structure, but actually strengthens it. After the procedure, the tooth can bear up to 50 to 75 percent more chewing force.
An inlay is done when the tooth structure replaced is within the cusp tips of the tooth. If the damage is more extensive and the new structure covers the entire chewing surface including one or more tooth cusps, the procedure is called an onlay.
*The average cost for inlays is $700 to $800, and for onlays, between $800 and $920, on average.
Inlays and Onlays offer a well-fitting, stronger, longer lasting reparative solution to tooth.

What are the most common benefits of inlays and onlays?
Inlays and onlays are ways of repairing relatively extensive tooth decay or damage without having to replace the whole outer portion of the tooth as with a crown. Less tooth material is removed so inlays and onlays tend to be more conservative and esthetic than crowns. Unlike fillings, these procedures strengthen a tooth's structure. They also tend to last longer than a filling, because the inlay or onlay material is custom made and bonded to the tooth.
How is the procedure performed?
Inlays and onlays are performed using very similar procedures. Both require two trips to the dentist. At the first appointment, the dentist begins the procedure by numbing the area using a local anesthetic. The decay or damage is removed using a drill, preparing the tooth for its new surface. After all the damage is removed, an impression is made of the prepared tooth so the inlay or onlay material can be cast in a form that will fit the tooth exactly. A temporary restoration is placed on the tooth to protect it until the laboratory makes the new structure and it can be bonded to the tooth. This can take about two to three weeks.
Using the impression, a laboratory prepares the new tooth surface using gold, porcelain, or composite resin. Upon return to the dentist's office, the temporary restoration is removed and the surface is cleaned to prepare for the new structure. The dentist will then try in the new restoration to ensure that there is a correct fit that doesn't interfere with your bite. If the fit is good, using special cement or bonding, the inlay or onlay is permanently attached to the tooth. Some minor adjustment may need to be made to the restoration if there are interferences. To finish the procedure, the dentist will polish the cemented or bonded structure and tooth.
How long does the procedure take?
Generally, each visit will take about one hour, although the first appointment tends to be longer with an onlay as more tooth structure is removed.
Where will the procedure be performed?
The procedure is performed during two visits to the dentist's office.
How much pain is there?
Local anesthesia takes care of the pain that would occur with the preparation of the tooth. Residual pain after the preparation or after cementing the structure in place is relatively rare, and can usually be taken care of using over-the-counter medicines such as aspirin or acetaminophen.
What can I expect after the procedure?
After the procedure there may be a little discomfort with the inlay or onlay, but many people adapt immediately to the new chewing surfaces. Sometimes the tissue around the work is sore or the tooth is temporarily sensitive to cold or hot foods. These minor problems should resolve themselves in one or two days.
What is the recovery period like?
Recovery is often immediate, with any discomfort taken care of using over-the-counter medicines.
What is the long-term outcome like for most people?
Gold inlays and onlays will last 10 to 30 years, given proper care and avoidance of abuse. Although the structures do strengthen the teeth, it is still a good idea to avoid chewing ice, pits, or other very hard objects, as they could damage the work.
The ideal candidate will have too much damage or decay to be treated using a filling, but enough healthy tooth left that a crown is unnecessary.
Other important information
Note also that two visits to the dentist for an inlay or onlay, now generally necessity, may soon be a thing of the past. A new computer generated system has been developed that takes the impression and makes the inlay or onlay all in one step. This allows the preparation and bonding steps to be performed in one appointment.
Risks and Limitations:
The number of risks for inlays and onlays are very small. Many restoration procedures typically require local anesthesia and some people may have allergic reactions to the medication. Also, a very small number of people are allergic to one or more of the metals used in the inlay or onlay. In most cases, the dentist can use another material.
