A knocked-out tooth can often be saved if replaced within 30 minutes to an hour, so it is important to act quickly. First, be sure to touch the tooth only by the crown (the “top” or visible part of the tooth), never the roots. If it is dirty, rinse it gently with milk if possible (water only if not), and do not scrub or wrap it in any kind of fabric or cloth as this can damage the tooth. Try to slip the tooth back into the socket but do not force it; if it does not go in easily simply place the tooth in a glass of milk or in your mouth, keeping it moist at all times. Get to the dentist as soon as you can!
