I received Mercury poisoning from this horrible dentist Isabel Pimentel at Beloit Dental when she…read moredrilled into my silver fillings for almost two hours for a cavity. Those silver fillings are called Amalgams, basically half silver and half Mercury. The World Health Organization states that when a dentist drills into those fillings, it creates friction and heat, which releases Mercury poisonous vapors back into a persons lungs at up to 1,000 times above the safe level. The E.P.A states Mercury is the most toxic substance on the planet earth after radiation. I did not know this at the time, but this dentist knew all the controversies, but she was too vain to alert me, and did not care about my health, only the $1,400 she would receive for the faulty work. There are dentist that belong to the I.A.O.M.T that use precautions, proceedures, and equipment to do this work. Each week for two months the Mercury poisoning was incrementally damaging my entire body, I thought I was on my way to die. Much of my body began to recover after many months, but there is no cure, because the Mercury settles into fat cells of the entire body and brain, and never comes out. The brain is 80% fat. I am left with pressure in my head and tired alot, thanks to this vain person. Long term problems I have read are memory problems, dysfuntion in the immune system, kidney ailments, chronic fatigue, allergies, cardiovascular problems, alzheimers, antibiotic resistance, hearing loss, etc. I did not write this to hurt Isabel Pimental, but to save you from what I went thru and going thru. There are other areas about this dentist, but another time. May God guide you in your research, and hold Isabel Pimental to respectable humane standards. My advice about this dentist , run and do not look back !
