All about fluoride: Updated clinical report covers caries prevention inprimary careby Melinda B. Clark M.D., FAAP

Tooth decay remains one of the most common chronic diseases of childhood in the United States, but access todental care is a challenge for many. Dental caries disproportionately affects poor, young, minority populationsand children with special health care needs.

Good oral health is a necessary part of overall health, and poor oral health adversely impacts multiple chronicconditions. Failure to prevent caries has significant health, educational and financial consequences forindividuals and society.

Simple prevention measures in the home and primary care settings can save health care dollars.

Pediatricians frequently see young children and provide guidance on nutrition and oral hygiene. Thus, they areuniquely positioned to participate in the primary prevention of dental caries.

An updated AAP clinical report from the Section on Oral Health aims to assist pediatricians in maximizing theuse of fluoride for caries prevention while minimizing the risk of enamel fluorosis. It also clarifies the advicepediatricians should give regarding fluoride use in the home.

The report, Fluoride Use in Caries Prevention in the Primary Care Sett ing, is available athttps://doi.org/10.1542/peds.2020-034637 and will be published in the December issue of Pediatrics.

Toothpaste, fluoride varnish

The clinical report advises pediatricians on how to assess a child's caries risk and fluoride exposures to informfluoride decisions and provide targeted anticipatory guidance and education.

Recommendations that are unchanged from the 2014 report include use of fluoride toothpaste for all children assoon as the first tooth erupts. The quantity should be limited to a tiny "smear" or grain of rice until 3 years of age.After age 3, a pea-sized amount of fluoride toothpaste is recommended if the child can expectorate. Childrenshould spit without rinsing, and the toothbrush should be the last thing to touch the teeth at night.

Fluoride varnish application now is considered standard of care in pediatric primary care. The United StatesPreventive Services Task Force (USPSTF) recommends that primary care clinicians apply fluoride varnish to theteeth of all infants and children starting at tooth eruption through age 5 years. All children in this age categoryshould receive fluoride varnish application at least once every six months. Higher-risk children, including thosewith established dental caries, should have fluoride varnish applied every three months (four times per year) inthe medical home.

Medicaid will pay physicians for the application of fluoride varnish in all 50 states.

USPSTF and Bright Futures recommendations are considered standard of care. The Affordable Care Actrequires all public and private insurance plans to cover preventive care services without cost-sharing to patients

or families.

The report highlights the administration, billing and payment information regarding the fluoride varnishprocedure. The CPT code for fluoride varnish is 99188 and should be linked to ICD-10 code Z29.3, encounterfor prophylactic fluoride administration.

Other sources of fluoride

Over-the-counter fluoride mouth rinses continue to be recommended only for children 6 years of age and olderat high risk of caries.

Community water fluoridation provides topical and systemic fluoride exposure and aids in prevention of toothdecay. Water fluoridation is an effective and safe method of protecting the most vulnerable members of thepopulation from dental caries. Pediatricians are encouraged to advocate for public water fluoridation in theircommunities and states.

Dietary fluoride supplements should be considered for children from 6 months until 16 years of age who live incommunities where the water is not fluoridated or who drink nonfluoridated well water.

Silver diamine fluoride

The clinical report raises awareness about silver diamine fluoride (SDF), a minimally invasive, low-cost liquidnonsurgical technique used to manage carious lesions. SDF can arrest cavitated lesions as part of acomprehensive caries management program in the dental home.

Pediatricians are seeing increased numbers of SDF-treated teeth in their practice. They should understandindications for SDF and recognize the clinical appearance of SDF-treated teeth.
