Anyway, it’s much, much easier to test for mercury if you can simply cut away some tissue.
They checked mercury levels in persons who had never had any amalgam filling, in persons who had a moderate amount of amalgam fillings (between five and ten), and in persons who have had more than 15 amalgam fillings during at least 20 years of their lives.
The result of these measurements?
There was no relation whatsoever between the number of amalgam fillings and the amount of mercury in body tissues.
There’s no reason to have your amalgam fillings removed.
Actually the exact opposite of that is true:
This study provides support to the importance of dental amalgam as a source of I-Hg in both blood and brain. In addition, total-Hg concentration in pituitary and thyroid was strongly associated with the number of dental amal- gam surfaces. However, there is no evidence from epide- miological studies that exposure to dental amalgam restorations is associated with disease, impaired neu- ropsychological functions or prevalence of general health complaints [24-29]. Nevertheless, an association between amalgam exposure and subclinical neurological effects have been reported , which may be consistent with an association between cumulative amalgam exposure and some neurological diagnoses as reported by Bates et al. .
