If an adult tooth is knocked out try to save it and find a dentist ASAP. If dirty, rinse tooth in milk holding it by the crown (not roots). If milk is not available use water (for a few seconds only), then put the tooth back in the socket. If the tooth cannot be replanted, place it in milk or in the patient’s mouth inside the cheek. Go to a dentist within 30 minutes if you can. Time is critical for successful replanting. Baby teeth are never replanted; just leave them out.
