Invisalign is a safe and effective option for children and teens, but whether invisible braces are the right orthodontic treatment depends on the child. Some children may take them out if they’re uncomfortable. Your kid needs to be mature enough to understand why it’s so crucial to wear their invisible braces as directed and responsible enough to take proper care of the aligners and wear them for at least 22 hours a day. For severe dental concerns, such as impacted teeth or severe misalignment, Invisalign clear braces may not be the right option.
