Fluoride is a natural substance which helps protect our teeth
Numerous studies have shown that children and adults living in areas with community water fluoridation have significantly lower tooth decay than those living in non fluoridated areas. It makes them stronger and reduces tooth decay.
It's in many town water supply's across the country and in a variety of toothpastes available at the supermarket.
For more information about fluoride in water at the Ministry of Health website.
