i have Esthetic-x in my 2 fillings and it was done by a holistic dentist.
I really thought it was safe so when i found out it wasnt, i rang them up and they said they have had no problems with it and its safe.
Actually in the very beginning of ttreatment i opted to get all my mercury filled teeth pulled out to be on the safe side. In the end i ended up with 2 left which they filled, most of them were root canals anyway and they had to come out.
I had cavitation surgery instead of getting my teeth redone with safer materials because i thought it was more important, now il have to save up again for the 2 fillings, im opting for diamondlite.
