Which statement about fluoride supplements during pregnancy is supported by evidence?

• A. There is strong evidence they prevent offspring caries
• B. No evidence they prevent offspring caries
• C. Fluoride supplements are recommended for all pregnant women
• D. Fluoride supplements should be taken in high doses during pregnancy

Answer: (B)

The key idea is that giving fluoride to a pregnant person has not been shown to reduce caries in their children. Fluoride’s protective effect operates mainly when applied topically to the developing and erupting teeth, not through prenatal exposure. When studies look at maternal fluoride supplements during pregnancy, they have not demonstrated a consistent or meaningful decrease in offspring caries. As a result, guidelines do not endorse routine prenatal fluoride supplementation for caries prevention in the child. In fact, advocating high doses during pregnancy could raise safety concerns without offering proven benefit. The practical takeaway is to rely on established fluoride sources for the child after birth (such as appropriate fluoride toothpaste, water fluoridation where available, and professional applications) based on the child’s age and caries risk.
