Oral Care for Your Baby
Your baby may not yet have her first tooth, but you can still take care of her gums in preparation for a lifetime of good dental care. Simply wipe your child’s gums with a wet washcloth or a clean gauze pad after each feeding. Begin brushing your child’s teeth with a little water as soon as the first tooth appears. Supervise tooth brushing to make sure that children older than 2 years use only a pea-sized amount of fluoride toothpaste and avoid swallowing it. Children should be taught to spit out remaining tooth paste and rinse with water after brushing.
