Extent of Treatment
The extent of damage or decay requiring treatment can affect the overall cost of your procedure. In general, inlays are used for smaller areas and tend to cost less than onlays. However, if you need more extensive treatment, your dentist may recommend an onlay.
Sedation
While most patients undergo inlay and onlay placement with only local anesthesia, some prefer to be sedated during the procedure, especially if they have dental anxiety. Dental sedation will add to the overall price of your treatment and may not be covered by insurance.
