While thumb sucking may be a common habit with young children, some kids suck their lips rather than their thumbs. While this may seem a harmless enough habit, apart from the chapping and minor swelling it may cause, habitual sucking of a lip may sometimes affect your child's teeth. If your child constantly sucks on a lip, and you haven't figured out a way to get them to stop yet, then it's worth mentioning the habit to your dentist next time you take your child for a check-up.
