The adjustment of the fluoride level in community water supplies to optimal concentration is the most beneficial and inexpensive method of reducing the occurrence of caries. Epidemiologic data from the last half-century indicate reduc-
tions in caries of 55 to 60 percent, and recent data show caries reduction of approximately 25 percent, without significant enamel fluorosis, when domestic water supplies are fluoridated at an optimal level. Evidence accumulated from long-term
use of fluorides has demonstrated that the cost of oral health care for children can be reduced by as much as 50 percent.
These savings in health dollars accrue to private individuals, group purchasers, and government care programs. An even higher caries reduction can be obtained if the proper use of fluorides is combined with other dietary, oral hygiene, and preventive measures as prescribed by a dentist familiar with
the child’s oral health and family history.
