Fluoridation is based on 70 year old science.

Everyone should read the CURRENT science for themselves. Much of it is collected in this 
excellent book , "The Case Against Fluoride" authored by three scientists, one an M.D. It contains over 1200 scientific references (over 80 pages), showing that fluoride results in slow poisoning over a lifetime,  is ineffective for teeth and causes cancer, thyroid & pineal gland damage, broken hips from brittle bones, lowered IQ in children, kidney disease, arthritis and other serious health problems.　

Read chapter 15 "Fluoride and the Brain," to learn the awful truth for everyone, particularly children.
