You must see a dentist IMMEDIATELY! Time is a critical factor in saving the tooth. If possible, find the tooth. Handle it by the crown, not by the root. You may rinse the tooth with water only. DO NOT clean with soap, scrub or handle the tooth unnecessarily. Inspect the tooth for fractures. If it is sound, try to reinsert it in the socket. Hold the tooth in place by biting on a gauze or clean cloth. If you cannot reinsert the tooth, transport the tooth in a cup containing the patient’s saliva or milk, NOT water. If the child is old enough, the tooth may also be carried in their mouth (beside the cheek).
