Dental Amalgam

Dental Amalgam is a commonly used dental filling that has been used for over 150 years. Although we no longer place amalgam fillings in our office, it is still in use throughout the country. It is a mixture of mercury with at least one other metal (usually silver and copper). Amalgam has many advantages over other restorative material, such as low cost, strength, durability, and bacteriostatic effects.

Amalgam is used in dentistry for a number of reasons. It is relatively easy to use and manipulate during placement; it remains soft for a short time so it can be packed to fill any irregular volume, and then forms a hard compound. It is also one of the more economical dental restorative materials. Amalgam possesses greater longevity than other direct restorative materials, such as composite. On average, most amalgam restorations serve for 10 to 12 years, whereas resin-based composites serve for about half that time. However, with recent improvements in composite material science and a better understanding of the technique-sensitivity of placement, it should be noted that this difference is decreasing. It has been our experience that well placed composite restorations should last for 15 or more years when good oral hygiene is maintained.

There are circumstances in which composite (white fillings) serves better than amalgam; when amalgam is not indicated, or when a more conservative preparation would be beneficial, composite is the recommended restorative material. These situations would include small occlusal restorations, in which amalgam would require the removal of a more sound tooth structure, as well as in areas where the amalgam would be unsightly.

The American Dental Association Council on Scientific Affairs has concluded that both amalgam and composite materials are considered safe and effective for tooth restoration.
