Fluorosis is a discoloration of the teeth due to chronic excessive exposure to fluoride during tooth development. It is a cosmetic issue that does NOT affect systemic health.

Clinical Appearance

  • Usually consists of white mottling

Prevalence & Risk Factors

  • Prevalence of fluorosis (mostly mild) in the United States is 0.2%–27% and rising.
  • The risk of developing fluorosis is greatest at an intake of more than 0.06 milligram per kilogram of body weight per day.
  • Varnish is not a major risk factor for fluorosis as it is an irregular source of fluoride rather than a daily one.

Risk Reduction

  • Determine the fluoride content of the child's drinking water before prescribing supplements.
  • Avoid duplicate fluoride prescriptions.
  • Follow current dosage schedules for systemic fluoride supplementation.
  • Tell the child's caregiver to place only a smear (under two years) or pea size dab (children over age 3 or when the child can spit effectively) of fluoridated toothpaste on the child's toothbrush.
  • Keep fluoride-containing products out of the reach of small children.
