Onlay Restorations – Gramercy Park New York City

Onlay restorations are custom-made fillings that are made up of composite material.  These composite materials are made of gold or tooth colored porcelain. These fillings are made by professional dental laboratories and then are cemented permanently onto the tooth by the dentist.  Inlays and onlays are essentially identical and both very important to the overall hygiene of a mouth. The only exception is that onlays require the restoration of the chewing surface with the addition to the filling.

Onlays are used to conservatively repair teeth that have very large fillings that are defective. Sometimes these fillings may have been damaged by decay or trauma. An onlay is also sometimes referred to as a partial crown but they are an ideal alternative to crowns. The reason for this is because less of the tooth structure is removed in the preparation of these onlays. An onlay can be a good alternative to a crown or cap because there is less natural tooth structure removed in the preparation. Like most dental restorations, both inlays and onlays are highly durable and will last many years. Unfortunately, onlays are like most dental restorations and are not always permanents. They may someday require replacement.

What does getting an Onlay Restoration involve?

Two appointments are usually needed for an onlay procedure. The first appointment will include a few different steps. First the dentist will take multiple and highly accurate impressions which are also known as molds. These molds will be used by a dental laboratory in order to create your custom onlay and a temporary restoration.

The dentist will then remove any decay or old filling material while the tooth is numb. Then the space will be cleaned thoroughly and then prepared carefully. The dentist will then shape the surface in order to properly fit an onlay restoration. The patient will then receive a temporary filling. This will be applied in order to help protect the tooth until the onlay is made.

The second appointment is when the new onlay will carefully and correctly be cemented into place. A few alternations and adjustments may be made to ensure an accurate fit and bite. The dentist will then go into detail with instructions on how to take good care of the new onlay. Practicing good oral hygiene will also be discussed.
