Can nighttime breastfeeding cause cavities?

Q: My 2-year-old has cavities, and the dentist says it's because I breastfeed him at night. Is he right?

A: No, and what a shame that your dentist has taken a tough situation and made it worse by blaming you. Medical research on this topic is clear and solid: Breast milk does not cause cavities. Most experts agree that "luck of the draw" in the strength and integrity of tooth enamel determines who gets cavities. However, adding sugary foods and lots of juice to children's diets are also contributing factors and should be avoided.
