Dental Topics - Restoring Teeth
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.
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 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
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
