Topical fluoride strengthens the teeth once they have erupted by seeping into the outer surface of the tooth enamel, making the teeth more resistant to decay. We gain topical fluoride by using fluoride-containing dental products such as toothpaste, mouth rinses, and gels. Dr. Joyce and the dental hygienists generally recommend that children have a professional application of fluoride twice a year during dental check-ups.
Systemic fluoride strengthens the teeth that have erupted as well as those that are developing under the gums. We gain systemic fluoride from most foods and our community water supplies. It is also available as a supplement in drop or gel form and can be prescribed by Dr. Joyce or your physician. Generally, fluoride drops are recommended for infants, and tablets are best suited for children up through the teen years. It is very important to monitor the amounts of fluoride a child ingests. If too much fluoride is consumed while the teeth are developing, a condition called fluorosis (white spots on the teeth) may result.
