Inlays and onlays are indirect restorations used to repair damaged portions of a tooth. An inlay fits within the cusps, while an onlay extends over one or more cusps when more coverage is needed.
A dentist may recommend one when:
Your dentist will evaluate the tooth’s condition, remaining structure, damage, and bite before recommending the appropriate treatment. Patients with damaged or weakened teeth may also benefit from our comprehensive restorative dentistry services.
The main difference is how much of the tooth each restoration covers.
| Restoration | Coverage | General use |
| Inlay | Fits within the cusps. | Repairs damage primarily within the chewing surface. |
| Onlay | Covers one or more cusps. | Provides additional support when a larger area needs restoration. |
| Crown | Covers the visible portion of the tooth. | May be recommended when more extensive structural protection is needed. |
An inlay or onlay is not necessarily preferable to a crown in every situation. A crown may be appropriate when a tooth has extensive structural damage, while an inlay or onlay may be considered when sufficient healthy tooth structure remains.
If broader coverage is needed, dental crowns may be another treatment option to discuss with your dentist.
Inlays and onlays can be made from different materials, depending on the tooth, its location, functional demands, appearance, and other clinical considerations.
Common material categories include:
There is no single material that is right for every patient. The American Dental Association’s information on dental materials explains that materials have different properties and indications, so your dentist can help determine which option fits your particular tooth and treatment needs.
Treatment begins with an examination to determine whether the tooth can be restored with an inlay or onlay and whether another treatment would be more appropriate.
Depending on the restoration and treatment approach, the process may include:
The number of appointments can vary depending on the restoration and the approach used. Your dentist will explain the expected timeline before treatment begins.
Some patients may experience temporary sensitivity or tenderness following dental treatment. The extent and duration can vary, so discuss any concerns with your dental team.
If damage has extended into the tooth's pulp, an inlay or onlay may not be sufficient. In those cases, root canal treatment may be considered when clinically appropriate.
An inlay or onlay does not replace the need for everyday oral care. Continue brushing twice daily, cleaning between your teeth, and attending recommended dental examinations.
You can also help protect your restoration by avoiding habits that place unnecessary stress on your teeth, such as biting hard objects or using your teeth to open packages.
Contact Stunning Smiles if an inlay or onlay feels loose, becomes damaged, or your bite suddenly feels different. Regular dental visits allow your dentist to monitor the restoration and the surrounding tooth.
The lifespan of a restoration varies based on factors such as the material used, the condition of the tooth, oral hygiene, bite forces, and daily habits. No dental restoration can be expected to last indefinitely.
The estimated cost of a dental inlay or onlay is $700–$1,400 per tooth. The final price can vary depending on factors such as the material selected, the extent of tooth damage, and the treatment needed to prepare the tooth.
A dental examination is the best way to determine which restoration is appropriate and provide a more specific estimate based on your individual needs.
An examination can determine whether an inlay or onlay is suitable for your tooth based on its condition and remaining healthy structure. Stunning Smiles is located at 2345 4th St Ste A, Santa Rosa, CA 95404, and is open Monday through Thursday from 8 AM to 5 PM.

Once the restoration is placed and your dentist confirms your bite is comfortable, you can generally return to your usual diet. Follow any temporary dietary instructions provided.
Some materials may be affected by staining or changes in appearance. Your dentist can explain how your selected material may respond over time.
Yes. Cleaning between your teeth remains important after restoration. Your dental team can show you how to clean around the restored tooth.
You may notice a slight difference in how your teeth come together after placement. Your dentist can check the restoration and make adjustments if your bite does not feel comfortable.
They may eventually need replacement due to wear, damage, changes in the supporting tooth, or other concerns. Regular dental visits can help identify when attention is needed.
