Some thoughts on Metal fillings from your trusted Colorado Springs Dentist.
Silver fillings, also called dental amalgams, have created controversy among dental professionals and patients. Some countries such as Sweden, Denmark, and Norway have banned mercury in dental fillings. The metals in amalgam fillings include tin, copper, and silver and are bound together by mercury. Many studies have been done on the safety and possible hazards of mercury in dental fillings with conflicting results. California has attempted to ban amalgam use in fillings.
Some studies suggest mercury can cause behavioral changes, multiple sclerosis, autism, Alzheimer’s disease, and liver toxicity. Studies also conclude mercury vapor is released when brushing teeth, chewing gum, eating, and removing silver fillings. Some suggest the amount of mercury vapor released and its toxicity is dependent on the number of silver fillings.
On the other side of the issue the American Dental Association continues to support the use of amalgam fillings as a safe and effective filling material. This controversy has been ongoing for decades now. Using the experience of my 30 plus years as a dentist in Colorado Springs, I stopped using mercury/silver fillings in 1984 following both health concerns for my patients and the experience of seeing numerous cracked teeth as a result of the metal expansion of amalgam fillings, that like water that freezes in rocks, broke teeth over time as hot and cold foods and beverages were consumed.
There is no perfect filling material. My preference is the bonded composite materials (no mercury or silver) which have had major improvements since they were first introduced. If after a number of years the margins, that area where the tooth and filling material meet, begin to fail, it is visually obvious and lasers used for diagnosis can detect the problem. I simply change out the filling at that time.
I hope this helps you with any questions you may have about filling materials.
