Optimal Daily Fluoride Intake: Guidelines and Considerations
Recommended Fluoride Intake for Children
Fluoride Intake in Toddlers
Research indicates that the average daily fluoride intake for a two-year-old child living in areas with water fluoride levels ranging from 0.37 to 1.04 ppm is between 0.315 to 0.610 mg/day, which translates to 0.025 to 0.049 mg/kg body weight1. This intake is derived from food, water, and beverages.
Fluoride Intake in Infants
For infants aged 1 to 6 months, the daily fluoride intake ranges from 0.32 mg/day to 1.23 mg/day, depending on their age and food intake. This intake, when expressed per kilogram of body weight, ranges from 0.07 mg/kg in newborns to 0.16 mg/kg in six-month-old infants7.
Fluoride Intake in Young Children
Children aged 22-35 months in Colombian cities have been found to have a mean daily fluoride intake ranging from 0.07 to 0.21 mg/kg body weight, with higher intakes observed in children from lower socioeconomic statuses5. The primary sources of fluoride in these children’s diets are toothpaste, food, and beverages.
Fluoride Intake for Young Adults
Fluoride Intake in Adolescents
For young male adults aged 16 to 19 years, the average daily fluoride intake varies significantly based on geographic location and water fluoridation levels. In fluoridated cities, the intake ranges from 1.636 mg/day to 2.4 mg/day, while in non-fluoridated cities, it is lower, ranging from 0.86 mg/day to 0.912 mg/day2 3 6.
General Guidelines and Safety
Optimal Fluoride Intake
The optimal daily fluoride intake for children is generally considered to be between 0.05 to 0.07 mg per kilogram of body weight. This range is designed to maximize protection against dental caries while minimizing the risk of dental fluorosis4.
Sources of Fluoride
Fluoride intake comes from various sources, including drinking water, food, beverages, and dental products like toothpaste. For instance, in Brazilian children aged 1 to 3 years, toothpaste alone accounts for approximately 81.5% of their daily fluoride intake, with water and milk being significant dietary contributors10.
Monitoring and Recommendations
Given the variability in fluoride intake from different sources and the potential for dental fluorosis, it is crucial to monitor and manage fluoride exposure, especially in young children. Health authorities recommend using appropriate amounts of fluoridated toothpaste and educating parents on proper toothbrushing practices to avoid excessive fluoride ingestion5 9.
Conclusion
The recommended daily fluoride intake varies by age and geographic location, with specific guidelines suggesting 0.05 to 0.07 mg/kg body weight for children to balance the benefits of caries prevention and the risk of fluorosis. Monitoring fluoride sources and adhering to recommended guidelines can help maintain optimal fluoride levels for dental health.

Estimated Fluoride Intake of Average Two-year-old Children in Four Dietary Regions of the United States
An average two-year-old child in cities with water containing 0.37 to 1.04 ppm of fluoride has a daily fluoride intake of 0.315 to 0.610 mg/day from food, water, and beverages.
Observational StudyThe fluoride content of a representative diet of the young adult male.
A representative diet of 16-19 year old males contains 0.8 to 0.9 mg fluoride per day, well below toxic levels, and children up to 8 years of age do not experience toxic effects from fluoride.
Observational StudyFluoride intake of young male adults in the United States
Low levels of fluoride are consumed in the United States by young adult males aged 16-19 years, indicating a need for further research on fluoride intake.
Observational StudyReview of Fluoride Intake and Appropriateness of Current Guidelines
Current fluoride intake guidelines are inadequate for individuals due to varying fluoride metabolism, susceptibility windows, and other factors.
Literature ReviewTotal fluoride intake in children aged 22-35 months in four Colombian cities.
Children in three Colombian cities have a mean daily fluoride intake above the 'optimal range'; health authorities should promote appropriate use of fluoridated dentifrices and education on proper toothbrushing practices.
Observational StudyDietary Fluoride Intake of 15-19-year-old Male Adults Residing in the United States
In fluoridated cities, 15-19-year-old males have an average daily dietary fluoride intake of 1.85 mg/day, while in non-fluoridated cities, they have an average daily intake of 0.86 mg/day.
Observational StudyDietary fluoride intake of infants.
Infants aged 1 to 6 months have a dietary fluoride intake of 0.32 mg/day in the first 4 weeks, increasing to 1.23 mg/day in the next 4 months, and 0.16 mg/kg in the 6-month-old infant.
Estimated Dietary Fluoride Intake by 24-Month-Olds from Chocolate Bars, Cookies, Infant Cereals, and Chocolate Drinks in Brazil
High levels of fluoride in certain products significantly contribute to overall fluoride intake in 24-month-old children, highlighting the need for close monitoring and clear product labels.
Dietary fluoride intake of 6-month and 2-year-old children in four dietary regions of the United States.
Infants and toddlers in most cities with high fluoride levels have dietary fluoride intake within the optimum range, but ingestion of fluoride-containing dentifrice or milk formula diluted with fluoridated water may lead to higher intake levels.
Observational Study
Highly CitedFluoride ingestion from toothpaste and diet in 1- to 3-year-old Brazilian children.
Most 1- to 3-year-old Brazilian children have a daily fluoride intake above the recommended threshold for dental fluorosis, with dentifrice accounting for 81.5% of their intake, and fingernail fluoride levels not significantly affecting intake.
