Fluoride - Children's Hygiene

When present in water or vitamins, the fluoride ion soaks into the tooth and makes the tooth less soluble to the acidic by-products of bacteria. This chemical barrier to acids helps make the tooth resistant to decay. The optimum level of fluoride intake is low and more is not better. It is important to know whether or not your water supply is fluoridated. If it is, no other supplement is required.
