What forms of fluoride may be used to prevent dental caries?
Oral fluoride supplementation, available by prescription, is recommended for preschool children with fluoride-deficient water supplies. Professionally applied topical fluoride varnishes are adjuncts to this oral supplementation; these topical varnishes are approved to prevent dental caries in young children. Their advantages over the other topical fluoride agents, such as mouth-rinse and gel, include ease of use, patient acceptance, and reduced potential toxicity.
