The American Dental Association, along with a lot of research, says that the amount of mercury in amalgam fillings is too small to cause any health problems. The bigger problem, according to Dr. Clay Hansen, a dentist in Moscow, Idaho, is what these amalgam fillings do to the teeth themselves. As mercury expands, the fillings will expand in your mouth during temperature changes, such as when eating something hot or cold. Over time, the constant expanding and contracting can cause the tooth to crack and break. Additionally, it can cause a space between the filling and tooth, leaving room for food or bacteria.
Amalgam fillings can be replaced with tooth-colored composite fillings, depending on the size of the filling and the condition of the tooth. On lays and crowns can also be used to replace amalgam fillings, which look just like a natural tooth.
