There are several ways to make sure a child’s teeth are strong and resistant to cavities. Strong teeth start from within—water with fluoride and calcium-rich foods are both important for dental health. Your child should brush twice a day with fluoride toothpaste, and have fluoride treatments applied at least twice a year during their dental check-ups. If your child has a history of tooth decay, we may recommend fluoride treatments up to four times a year to keep their teeth healthy.
