If knocked out or broken, apply clean gauze to control bleeding and call the pediatric dentist.
If knocked out, handle the tooth by the top and not the root (the part that would be in the gum). If dirty, rinse gently without scrubbing or touching the root. Do not use any cleansers. Use cold running water or milk. Place the tooth in clean water or milk and transport the tooth with the child when seeking emergency care. Call and go directly to the pediatric dentist or an emergency department. If the tooth is broken, save the pieces in milk and call the pediatric dentist right away. Stop bleeding using gauze or a cotton ball and pressure in the socket.
