I have well water and do not use fluoridated toothpaste. Read this post and see what you think, then do some more research on the subject. You may not ever use fluoride again.
MOSAIC”S WARNING (pg. 2) “Prolonged or repeated overexposure to fluoride compounds may cause fluorosis. Fluorosis is characterized by skeletal changes, consisting of osteosclerosis (hardening or abnormal density of bone) and osteomalacia (softening of bones) and by mottled discoloration of the enamel of teeth (if exposure occurs during enamel formation). Symptoms may include bone and joint pain and limited range of motion. Conditions aggravated by exposure may include skin and respiratory (asthma-like) disorders.”
