Yes, several mercury fillings, maybe 16 all up; and one of which was a root canal filled with mercury which over time gave me neurological symptoms including bells palsy symptoms, facial bloating and dropping on L side, for years. Neurologists actually diagnosed me with Melkerson's Rosenthal Syndrome which has the same symptomotology (put on beta blockers and anti inflammatories)...But all it was due to mercury poisoning which then lead to a whole host of other problems including my thyroid problems. It all makes sense now, 20 years later; and after removal of the offending tooth. I wish I knew every thing I do now, back then. I could have avoided unnecessary surgery and years of discomfort and toxic damage. Its all good reason to stay away from mercury dentists and other conventional doctors.
