    Area of Science:

    • Oral health
    • Public health
    • Prenatal care

    Background:

    • Fluoride supplementation during pregnancy is a strategy to improve offspring dental health.
    • Determining optimal and safe prenatal fluoride dosage is crucial for public health recommendations.

    Purpose of the Study:

    • To evaluate the safety margin of prenatal fluoride concerning dental fluorosis.
    • To establish a simplified and universally applicable prenatal fluoride dosage.

    Main Methods:

    • Review of existing data on prenatal fluoride exposure and fluorosis risk.
    • Analysis of safety margins for various prenatal fluoride intake levels.

    Main Results:

    • A wide safety margin exists for prenatal fluoride intake concerning dental fluorosis.
    • A dosage of 2 mg/day is identified as a safe and simplified option for all areas.
    • Prenatal fluoride dosages between 1-4 mg/day are demonstrably beneficial compared to no supplementation.

    Conclusions:

    • The established safety margin supports a simplified prenatal fluoride dosage of 2 mg/day.
    • Universal recommendation of 2 mg/day prenatal fluoride is feasible, irrespective of water fluoridation status.
    • Prenatal fluoride supplementation within the 1-4 mg/day range is advantageous for dental health.
