A concern we often hear about in our Tampa dental office is regarding silver fillings, and whether they are safe. For a long time amalgam fillings, also known as silver fillings, were the only option for fixing dental cavities. Over time, questions have been raised as to the safety of amalgam fillings, due to the fact that they contain mercury.
Amalgam, which has been the most widely used and effective dental filling material for the past 150 years, is comprised of a number of metals. These metals include silver, mercury, tin, and copper. Minimal amounts of zinc, indium, or palladium may be used. More recently, advancements in dentistry have led to alternative materials, which can be used in many cases. Amalgam fillings are less expensive than these newer types of fillings, and in some cases have been shown to wear better.
In response to concerns about amalgam, numerous studies have been conducted on the safety of amalgam fillings. In 2009, the U.S. Food and Drug Administration (FDA) studied the data and found no reason to halt or curb the use of amalgam. The FDA concluded that amalgam fillings are safe for adults and children ages 6 and above.
At Weninger Dentistry, we understand that many patients still have concerns regarding the use of amalgam fillings. That is why we offer our patients an alternative with mercury-free dentistry. We offer new advanced composite fillings made of tooth-colored materials that contain no metal.
A benefit composite fillings offer over traditional metal fillings is the ability to match natural tooth color. Consisting of plastic and glass particles, composite fillings are a desirable filling materials because of the aesthetic benefits. They also provide the advantage of solidly bond to the tooth. Since the composite fillings are hardened by applying a high intensity blue light, it only takes a few seconds for the materials to set.
