Note this special guest post submitted by Maddaz A. Hatter, D.D.S. Thanks Dr. Hatter!
Also, on an almost-completely-unrelated note, skeptical dentist, haberdasher extraordinaire, and sometime-guest-blogger Grant Ritchey recently moderated debate between SBM regular Clay Jones, and pediatrician-who-has-yet-to-be-coerced-into-blogging-with-us Raymond Cattaneo, about the pros and cons of firing families who refuse to vaccinate according to the recommended schedule. I’m told Clay wins the debate through a swift blow to the throat, but it happens at the very end so you’ll have to listen to the whole thing!

In England during the 1700s and 1800s, felt hats – very fashionable at the time – contained trace amounts of mercury, and many of the workers in the hat factories that produced them succumbed to mercury poisoning over time. Symptoms of mercury poisoning include dementia and other neurological complications, from whence came the term “Mad as a Hatter.” We’ve known for quite a while that quicksilver in large enough quantities does not do a body (or brain) good.
This brings up a point. It seems that a recurring theme at Science Based Medicine is that we are always defending what legitimate health care providers want to put into a human body to prevent, cure, or manage disease, or to improve health or quality of life. Conversely, we critique those who want to put things in us that are of no demonstrable benefit or which may cause harm. To wit: vaccines – good, coffee enemas – not good. Fluoride (at appropriate doses) – good, colloidal silver – not good. This is an ongoing tug-of-war that will likely continue until our sun supernovas and consumes our planet, after which all arguments will probably be moot.
In the dental field, the two biggest battles we seem to continually wage deal with the safety of fluoride and the use of dental amalgam. Fluoride and fluoridation has been written about many times before on Science-Based Medicine. I have also discussed it several times on my podcast, The Prism Podcast, but I’ve never written about amalgam fillings before. Harriet Hall wrote an excellent SBM post on the matter way back in 2008, but after all these years it’s probably time to revisit the topic. (more…)
