Today, dental research supports the use of a rice-sized smear of fluoridated toothpaste when brushing baby teeth. At this small of an amount, any accidental ingestion is safe. Too much could cause an upset stomach, so save the “pea sized” amount for when your child is old enough to rinse her mouth well.
Professional fluoride applications are recommended twice a year, usually during your child’s checkup and cleaning appointment. This treatment remineralizes any weaker outer enamel that’s been exposed to acids or sugars, strengthening it against potential tooth decay.
