      Do you find yourself hanging out at your local coal mine? Do you love to feast on large amounts of shark or swordfish? If you answered “yes” to either of these questions you may be at risk for mercury poisoning. However, if you’re consumed with worry that those little silver fillings in the back of your mouth are poisoning you, just relax and get back to your fish fest; your fillings are harmless.

silver fillings dentist reviewMyth: All silver amalgam fillings should be replaced for fear of mercury poisoning.

Fact: There are many things that may cause mercury poisoning, but according to the American Dental Association, silver amalgam fillings ain’t one of ‘em.

Like most controversial topics, there are two sides to this story. Some dentists believe the mercury from silver amalgam fillings can leak out of the filling and into your body causing health problems. If you search youtube you’ll find there’s no shortage of dentists (or actors who play one on TV) trying to convince you that silver amalgam fillings are harmful and need to be replaced. The ADA, the watchdog of dental practices, is in agreement with most major health agencies and scientific bodies that silver amalgam is safe and reliable. The ADA states, “…the mercury in amalgam combines with other metals to render it stable and safe for use in filling teeth”. In addition, research has failed to show any link between amalgam restoration and health problems.

Of course, there will likely come a time when an amalgam filling needs to be replaced due to it being old and cracked or worn. When that day arrives, you’ll want to find a well reviewed dentist who makes certain to use safe practices when replacing these fillings. Dr. Eccles, located in Livermore, California, is one of many dentists who specialize in health-centered dentistry.

Be sure to listen with a cautious ear when a dentist urges you to replace your silver fillings because they are a health risk. If the fillings are still in good condition, it’s quite possible it’s not your fillings that need replacing, but your dentist’s BMW.

    I am not a big specialist, but in order to avoid controversially harmful effects of silver amalgam it is possible to use any other type of fillings, like white composite fillings or something else, am I wrong?

    Yes, dentists can use various types of fillings. The controversy lies in whether they should remove old silver fillings that are still in good working condition. Thanks for your comment!

    Hello
    This Is Dr.Ligaya,

    The first trick to finding a good dentist to check a list of names compiled, too. You can talk to this list, friends and family to go to the dentist, or contact the Family Dental Association dentists in your area to find.

    Thanking you……..

    While Amalgam fillings are shown not to hurt people who have them…what are your comments about the growing research linking mercury to autism in children. While most of the research discusses immunizations only…there is in fact a lot of controversy about those fillings that you say are safe. How on earth can ANY amount of mercury placed directly into your mouth be safe? I sat in on a presentation a few months ago at my university. The professor showed us a 30 year old filling that was STILL giving off mercury vapors! It seems strange for any medical professional to hint “well mercury is already all around us in America…what else can this little bit hurt?” I’d suggest looking into the increased number of autistic children! As an Early Childhood Education Specialist…I can’t believe that anyone would take a side on this issue as a professional when the research is so blatantly biased thus far. I’d suggest to anyone that they do tons of their own research rather than reading one article and relaxing with a sigh of relief. For every person willing to say ‘yeah amalgam fillings are safe” there are twice as many who are willing to say “I’m not so sure they are but the proof is still yet to be solidified”

    Angela, I agree, one should always do their own research on such topics. I’d like for one of our dentists to comment on the average age that children have their first filling in relation to the average age that autism is diagnosed. As far as I know, children are usually diagnosed with autism at early ages, sometimes years earlier than they would have their first fillings, making it difficult to link the two. Again, I’d be interested to hear the expert’s take on this issue. Thanks for your comment!

    Here are some links that show the dangers of amalgam and other forms of mercury. Increasing levels of electromagnetic fields add to the health risks:

    Mercury release from dental amalgam restorations after magnetic resonance imaging and following mobile phone use.

    In the 1st phase of this study, thirty patients were investigated. Five milliliter stimulated saliva was collected just before and after MRI. The magnetic flux density was 0.23 T and the duration of exposure of patients to magnetic field was 30 minutes. In the 2nd phase, fourteen female healthy University students who had not used mobile phones before the study and did not have any previous amalgam restorations were investigated. Dental amalgam restoration was performed for all 14 students. Their urine samples were collected before amalgam restoration and at days 1, 2, 3 and 4 after restoration. The mean +/- SD saliva Hg concentrations of the patients before and after MRI were 8.6 +/- 3.0 and 11.3 +/- 5.3 microg L(-1), respectively (p < 0.01). A statistical significant (p < 0.05) higher concentration was observed in the students used mobile phone. The mean +/- SE urinary Hg concentrations of the students who used mobile phones were 2.43 +/- 0.25, 2.71 +/- 0.27, 3.79 +/- 0.25, 4.8 +/- 0.27 and 4.5 +/- 0.32 microg L(-1) before the amalgam restoration and at days 1, 2, 3 and 4, respectively. Whereas the respective Hg concentrations in the controls, were 2.07 +/- 0.22, 2.34 +/- 0.30, 2.51 +/- 0.25, 2.66 +/- 0.24 and 2.76 +/- 0.32 microg L(-1). It appears that MRI and microwave radiation emitted from mobile phones significantly release mercury from dental amalgam restoration. Further research is needed to clarify whether other common sources of electromagnetic field exposure may cause alterations in dental amalgam and accelerate the release of mercury.
