Q: Do dentists and health experts support fluoride in the water supply?A: Yes, all major dental and medical organizations support water fluoridation.
Q: Can too much fluoride cause fluorosis, which are brown spots on your teeth?A: Yes, high levels of natural fluoride in the water can cause fluorosis.

Q: Do Reverse Osmosis systems, water filters or water softeners remove fluoride from water?A: "Reverse osmosis systems remove fluoride from household drinking water as well as the protective effects that fluoridated water has on oral health.
Water softeners use an ion exchange resin that replaces calcium ion within hard water with a sodium ion that results in softer water. So, water softeners do not affect fluoride levels. "

Other home water filtration systems, like Pur or Brita, do not remove fluoride or it's protective benefits from water.
