The American Dental Association and other health organizations provide specific guidelines on fluoride intake. For children, it is generally recommended that they receive fluoride through both systemic (water, supplements) and topical (toothpaste, mouth rinses) sources. The exact amount varies by age; for example, children aged 6 months to 16 years should receive 0.25 to 1 mg of fluoride per day, depending on their age and exposure to other sources of fluoride.
