Gum receding in children, do they grow back to normal over time?

See a dentist : Gum recession is the process in which the margin of the gum tissue that surrounds the teeth wears away, or pulls back, exposing more of the tooth, or the tooth's root. Receding gums may be one of the first signs of gum disease. Gum recession is not something you want to ignore. If you think your child's gums are receding, make an appointment with your dentist.
