Loose teeth can take time to come out. The process of detaching from the roots can be a long one. DO NOT tie a string to a door and to their tooth. Please avoid any drastic physical actions to take out a tooth. It can be extremely painful, cause bleeding, and also damage your child’s mouth. Instead, encourage your child to wiggle their tooth gently to help coax it out. If you are still concerned, consider bringing your child to a dentist to have it pulled out professionally.
