Inlays & Onlays

Inlays & Onlays:

An inlay is usually an indirect restoration (filling) consisting of a solid substance fitted to a cavity in a tooth and cemented into place.

This technique involves fabricating the restoration outside of the mouth using the dental impressions of the prepared tooth, rather than placing a soft filling into the prepared tooth before the material sets hard.

An onlay is the same as an inlay, except that it incorporates a replacement for a tooth cusp by covering the area where the missing cusp would be.

Getting inlays or onlays have plenty of benefits such as:


  1. Esthetic appeal. Inlays and onlays are made of either composite resin or porcelain, both of which can easily be mixed to achieve the exact color of your teeth. Not only does this result in a natural appearance, it also hides the fact that you have a dental restoration.
  2. Ease of cleaning. Inlays and onlays become part of the tooth once placed, so you can easily brush and floss your teeth like you usually do. These dental restorations don’t require any extra care or maintenance.
  3. Durability. The materials used for creating inlays and onlays are very durable and resistance to pressure. If used properly, these dental restorations can last for the patient’s entire lifetime.
  4. Excellent fit. Since inlays and onlays are custom made based on your tooth’s actual mold, you get a dental prosthetic that fits your tooth as exactly as possible. Every single groove and pit on your original tooth can be copied into the inlay or onlay, ensuring a tight and seamless fit.
  5. Tooth preservation. Unlike getting crowns where your tooth needs to be trimmed into an abutment, inlays and onlays only require the dentist to remove the most damaged parts of the tooth, thereby saving most of the healthy tooth mass.
  6. Enhanced tooth strength. An inlay or onlay helps stabilize the tooth and prevents bacteria from spreading further. The healthy tooth mass will also remain intact and become more resistant to wear when an inlay or onlay is in place.
