The American Dental Association recommends that children and adults use fluoride toothpaste displaying the ADA Seal of Acceptance. For children younger than 3 years, you should begin brushing your children’s teeth as soon as they start to appear in the mouth by using fluoride toothpaste in an amount no more than a smear or the size of a grain of rice. You should be brushing their teeth thoroughly twice a day (morning and night) or as directed by your dentist or physician. For children 3 to 6 years of age, dispense no more than a pea-sized amount of fluoride toothpaste and brush teeth thoroughly twice per day. Always supervise your child’s brushing to ensure that they use the appropriate amount of toothpaste and try and get your child to spit out most of the toothpaste.
