Inlays & Onlays
“Don’t let damage get in the way of your smile!”
We, at Amir Sanjabi, DDS, help you make the right restorative treatment choices for your teeth. We offer inlay and onlay treatments that can repair damaged or decayed tooth and bring your smile back to its best state.
Inlays and onlays, also known as indirect fillings, are used when the damage to your tooth is extensive enough that just a filling is not enough, but not so bad that you would need a dental crown. These treatments are less aggressive and serve to keep your natural tooth as intact as possible. Unlike regular fillings, these inlays and onlays are fabricated outside of the mouth, in dental labs, and then bonded to your teeth.
Difference between Inlays and Onlays
An inlay is a customized filling that that is fitted to the pits and fissures of a tooth and do not extend to its cusps. The inlay is bonded to the tooth and can improve the strength of the tooth. Inlays are fabricated from gold, porcelain, and composite resin material and are much more durable than traditional fillings. Gold inlays are the most durable out of all the material used and are very expensive as well.
An onlay is a method to restore more extensive damage that affects the cusps and the biting surface of the tooth. Like inlays, they fit inside the tooth but extend to the cusps as well. These fittings are great for you if your tooth’s damage cannot be fixed with an inlay, but it doesn’t quite require a crown or cap.
It is difficult for a patient to determine whether they need an inlay or an onlay instead of a crown. We recommend visiting our clinic to find out if you are a candidate for an inlay or onlay.
Fitting Method of Inlays and Onlays
Getting an inlay or onlay will require at least two visits to our office. The procedure is pretty similar to what you may experience when you get a crown; however, there are a few important distinctions. When you need a crown, the enamel of your natural tooth starts to erode, and the tooth is shaped to accommodate the crown. However, with inlays and onlays, very little of your natural tooth structure needs to be removed, as the goal is to preserve as much natural tooth as possible.
The first step in getting an inlay or onlay is to anesthetize the tooth’s surrounding area and to remove decay and debris from the cavity. We do this to prevent decay and infection from going deeper into the tooth. Once the tooth is prepared, a putty-like material or a digital scanner is used to take the impression of your tooth. The impression is sent to the laboratory where a model is made for the fabrication of your inlays or onlays.
Your dentist will then place a temporary filling in your cavity to protect it. During your second visit, we will seal the inlay or onlay to your tooth with dental cement.
