The present study demonstrates that, in spite of the high fluoride dose administered to the mother (11.25 mg), the child receives a maximum dose of 30 ug fluoride/day, or 0.2% of the dose given to the mother. This is only 3% of the dose compared with the daily fluoride dose to bottle-fed children. With a baby formula diluted with 1 ppm fluoride water, bottle-fed children receive approximately 1 mg/day.

In conclusion, this study shows that there is a slight increase in the fluoride concentration in breast milk following the intake of high doses of fluoride. In spite of this, the fluoride supply to the infant through the breast milk is very low compared to what it may receive from other sources, such as drinking water containing fluoride.
