Numerous studies show the incidence in primary teeth are reduced by 50% when children receive a daily flouride supplement from birth. Based on these studies the American Academy of Pediatrics recommends continuous flouride supplementation up to age 16 in areas where drinking water contains less than optimal levels of flouride. For best results, flouride supplementation must be givenon a consistent, long term basis. So be sure to use the prescribed flouride vitamin supplement on a daily basis for as long as recommended.
