Fluoridation in New Zealand
Water fluoridation
Water fluoridation is the process of adjusting the natural level of fluoride in the water supply to between 0.7 ppm and 1.0 ppm. This is the optimal amount that provides protection against tooth decay. The amount added is monitored to make sure that the levels stay within that range.
Water fluoridation is a proven public health measure to reduce dental caries.
Along with brushing twice a day, eating healthy foods and timely check-ups with a dental provider, water fluoridation can have significant benefits to an individual.
Studies show that water fluoridation provides benefits above and beyond those from other fluoride vehicles alone.
