When you have a cavity in one of your anterior teeth, the standard procedure is to fill it with a tooth-colored filling material. Any discoloration or anomalies in these teeth can have a devastating effect on the appearance of your smile. These tooth-colored fillings are made from composite resin. They have been the standard filling material for front teeth for several decades.

Until recently, composites were seldom used in posterior teeth. This is because earlier versions of the material were not strong enough nor durable enough to withstand the pressures back teeth must endure. Thanks to advances in dental technologies and materials, composite resins can now be used to repair posterior as well as anterior teeth.

This material provides an authentic-looking finish to the affected tooth. It also feels as natural as it looks. With the improvements made in composite materials, even some large cavities can be filled, giving your entire mouth a more natural and blemish-free appearance.

What is a Composite Resin?

Plastic polymer is combined with glass or ceramic to create composite resin. Used for decades in anterior teeth, the evolution of these filling materials have led to composite resins that are strong enough to withstand the hundreds of pounds of pressure exerted on back teeth. They also last for years with proper oral hygiene.

There are many types of composites. Each type has its advantages. Many use a special blue light to harden the material, which is put down in layers. Each layer is exposed to the light until it cures. The light activates a reaction in the material that makes it hard. This ensures a durable, strong filling that will last.

Another advantage of composite fillings is they do not require unnecessary loss of healthy tooth structure. Amalgam, or silver fillings, need to be prepared in such a way as to hold the filling in the tooth. This means healthy tooth structure must be ground away to allow for the secure packing of the amalgam. Composite resins use a bonding material to bind the resin to the tooth structure. Only decayed or damaged tooth material is removed, leaving the healthy structure intact.
