From the moment babies are born, parents should help them develop good oral hygiene habits and clean their babies’ mouths every day. Parents should scrub their baby’s mouth with soft gauze once a day after birth even if they don’t have a single tooth, which is a beneficial way of parent-child interaction and helps babies develop good oral cleaning habits in the early years. How can parents do oral cleaning for their babies? For babies without teeth, the easiest way is to wrap clean fingers around a clean soft cotton gauze or use a cotton swab, dipped in warm water to gently wipe the baby’s oral cavity and palate, because the baby’s cavity is much more delicate than the adult’s, pay attention to gentle movements. Wipe once a day. After the baby’s teeth have erupted, you can continue to use this method to scrub the baby’s mouth and tooth surfaces. When your baby has 8 teeth, parents can use a finger toothbrush or a small-headed children’s toothbrush to brush your child’s teeth twice a day.
