Dental Fillings

There are many types of filling materials available, each with their own advantages and disadvantages. Composite fillings, along with silver amalgam fillings, are the most widely used today. Because composite fillings are tooth colored, they can be closely matched to the color of existing teeth, and are more esthetically suited for teeth. Amalgam fillings are made of metal and can provide a much more durable restoration. If needed, the dentist will discuss the best options for restoring your teeth. As with most dental restorations, amalgam or composite fillings will not last forever and will someday have to be replaced. 
Tooth Colored (composite) Fillings
A composite filling can be used to repair a damaged tooth. The damaged portion of the tooth will be removed and then filled with a composite filling. Composite can also be used to fix minor cosmetics issues such as spaces between the teeth. Composites are used to repair both front and back teeth.
Silver (amalgam) Fillings
An amalgam filling can also be used to repair a tooth that is damaged. This material is most commonly used on back teeth that are either decayed or broken.
