The Benefits of Composite Fillings

The History of Fillings

Once upon a time, the choices for dental restoration materials were limited. Records dating back as far as 659 A.D. tell us that amalgams (mixtures of silver, mercury, tin, and/or copper) have been used widely for more than 1300 years. 

There have been a number of scientific disputes (referred to as the amalgam war) over the health concerns of using mercury, but the American Dental Association has always defended the safety of amalgam fillings. Until recently, amalgam fillings were favored because of their strength, resilience, and relative ease of preparation and placement. In spite of their positive qualities, amalgams have three main drawbacks:

1. They are not aesthetically pleasing, may corrode or stain teeth
2. They require the removal of some healthy tooth structure
3. They expand and contract, which can cause teeth to crack

Composite Fillings

Modern dentistry offers many options for dental restorations. The most commonly used fillings are made of gold, amalgam, composite, or porcelain. Dr. Baird prefers composite fillings because they are: 

1. Strong
2. Tooth-colored
3. Can be placed in a single visit
4. Require very little removal of healthy tooth structure
5. Allow for easy identification of tooth decay nearby
6. Bond extremely well to enamel

Composite resin fillings are made from powdered glass and plastic, which is placed directly on the tooth in thin layers, then shaped and polished. Dr. Baird uses a special curing light source to accelerate the bonding process. 

Composite fillings are generally more durable than porcelain, significantly less expensive than gold, and do not expand and contract like amalgam fillings. Bountiful patients often prefer composite fillings because they look just like natural teeth.
