Regarding the October 2014 “Mouths of Mercury” column by Kate Madden Yee in the East Bay Medical Guide: Perhaps a bit more inquiry might have been in order. I am not an amalgam-filling proponent, as I have never placed a silver filling in my 20-plus-year career, but amalgam fillings last a hell of a lot longer than 12 years. In my practice, the vast majority of patients that have amalgam fillings have had them over 50 years, and the vast majority of my patients’ composite fillings last 10 to 20 years. Heck, I have perfectly good silver fillings that were placed in the late 1960s and early ’70s and composite fillings that were placed in the early 1980s. Amalgam and composites fillings have no expiration date. They fail due to recurrent decay, fatigue of the tooth, or faulty placement.
