Fluoridation in drinking water at permissible limits prevents tooth decay .
Fluoride does not make water safer. It is only added to prevent tooth decay. Above certain levels, it can cause mottling of teeth. It is a hazardous chemical to handle and is extremely corrosive. In today's society, we get enough fluoride from our toothpaste and mouthwash. No need to add fluoride to water. It is a waste of money and is dangerous for those who have to handle it.
