This is why you need to be particularly careful in today's over-fluoridated world, where water supplies, plus toothpastes, plus dental rinses, and other treatments all want to put more fluoride into our systems.
Some experts recommend you avoid fluoridated water -- try a bottled water that you've verified is fluoride free, and avoid fluoride treatments and fluoridated toothpaste.
For more information, see: Drs. Richard and Karilee Shames' discussion of the issue of fluoride and thyroid disease, as well as other Thyroid/Fluoride Links.
