Composite Fillings

A dental filling (also called a dental restoration) may last many years before it needs to be replaced. However, there are a number of reasons that fillings may need to be replaced. Constant stress from chewing, grinding and clenching teeth may eventually cause a filling to chip, crack, wear down, or fall out.

We use ‘composite’ if a tooth has decay or has a filling that needs to be replaced. Composite fillings are a mixture of glass or quartz filler in a resin medium that produces a tooth-colored filling. Composite fillings provide good durability and resistance to fracture in small-to-midsize restorations that need to withstand moderate chewing pressure.

Less tooth structure is removed when the dentist prepares the tooth, and this may result in a smaller filling that that of an amalgam (silver filling). Composites also are “bonded” or adhesively held in a cavity, often allowing the dentist to make a more conservative repair to the tooth.

Unfortunately accidents do happen. This child hit his front tooth and broke it. By placing a composite, we were able to build the tooth back up to look like a natural tooth!

This young boy hit his front teeth. We replaced the broken part of both teeth with composites.
