If you can, try to find the knocked-out tooth. Handling the tooth only by the crown and not the root, you may rinse it with water only. Under no circumstances should you scrub the tooth, clean it with soap, or otherwise handle the tooth unnecessarily. Have your child bite down on a clean cloth or gauze to hold the tooth in place; however, if you cannot reinsert the tooth, transport it in a cup containing milk or the patient’s saliva (NOT water.) Additionally, the tooth may be carried beside the cheek in the child’s mouth if they are old enough. It’s crucial that you visit a dentist IMMEDIATELY to increase their chances of saving the tooth.
