What are Dental Restorations?
The restoration of a tooth means to restore that tooth back to normal form and function.  A tooth needs to be restored for a variety of reasons - such as to fix a cavity, to repair a cracked or broken tooth, or possibly following root canal therapy.  Below are some of the options available in restoring a tooth.

Composite Fillings
Tooth-colored fillings that are designed to match the color of your teeth are called composites. Composites are a mixture of glass or quartz filler that provide good durability and resistance to fracture in small- to mid-size restorations that need to withstand moderate pressure from chewing. They are generally used on either front or back teeth. Composites are "bonded" or adhered in a cavity. This can allow us to make a more conservative repair to your tooth, meaning less tooth structure is removed when the tooth is prepared. This may result in a smaller filling than that of a metal (amalgam) filling.

Onlays
Onlays are types of fillings that are processed in the dental lab.  They are made of materials similar to Composites or from Porcelain-type materials.  They are then bonded to the tooth like Composite fillings. Onlays have more durability and higher bond strength than chair-side Composite fillings and are therefore suited to mid-size to large restorations.

Crown

A crown is a covering that is placed entirely overtop of a prepared tooth. A crown can help strengthen a tooth with a large filling when there isn’t enough tooth remaining to hold the filling. Crowns can also be used to attach bridges, protect a weak tooth from breaking or restore one that’s already broken. It’s also used to cover a dental implant. Crowns are indicated in specific situations and can be made from metal, porcelain-fused to metal, or all-porcelain crowns. Depending on the material they are either cemented or bonded to the tooth underneath.
