Hi Jiggy,
If they were smart, They would have know first that,
dental floss has traces of mercury in them but not fishing line, so if mercury is toxic for fish, then why not humans? That is a bunch of crock! Also, they tell you to be careful with a mouth thermometor because of mercury in them. I don't understand the logic behind it, It almost makes you think that they are trying to have population control and kill most of us off!@~*> Find yourself a dentist that will remove that toxic crap out of your mouth so that you can regain your health.
Take care,
Robbie
