What is water fluoridation?
Water fluoridation is the controlled addition of fluoride to a community water supply to reduce tooth decay. Fluoride's effects depend on the total daily intake of fluoride from all sources. Drinking water is typically the largest source. Fluoridated water has fluoride to a level that is effective for preventing cavities. Water fluoridation prevents cavities in both adults and children. Studies have shown an estimated 18 to 40 per cent reduction in cavities when water fluoridation is used by children who already have access to toothpaste and other sources of fluoride. Health and dental organisations worldwide have endorsed its effectiveness.
How do I know if my family is getting enough fluoride?
Drinking fluoridated water and brushing with a fluoridated toothpaste is considered sufficient for adults and children with healthy teeth. Dentists may prescribe fluoride tablets or drops for your children to take daily if the community water supply is not fluoridated. If your water comes from a public water supply, you can call your local water district to know if it is fluoridated. World Health Organisation expert committee suggests a level of fluoride from 0.5 to 1.0 mg/L (milligrams per liter), depending on the climate.
