One of the many ways to increase fluoride levels is through fluoridated water. Community water fluoridation has had such a dramatic effect in decreasing tooth decay that it has been endorsed by the American Medical Association, American Dental Association, and the World Health Organization.
Fluoride can also be found in toothpaste and mouthwash. Floss hygienists recommend brushing twice a day with fluoride toothpaste that has the approved ADA seal. Children under 3 years can use a smear the size of a grain of rice as soon as their first tooth erupts, and children 3-6 years should be using a pea-size amount. Mouthwash can be used on children 6 years and older.
Your Floss hygienists also recommend a fluoride varnish application with your cleanings that will slowly be absorbed to strengthen the enamel and/or a prescription strength fluoride toothpaste.
