Carefully pick up the tooth from the top of the crown and do not touch the roots. Gently rinse the tooth with water but do not scrub or touch any part of the tooth other than the crown. Holding the tooth by the crown, carefully put the tooth back in its socket. Then try biting down. If the tooth does not go back into the socket, put the tooth in a container with milk or water to keep the tooth wet. Seeing us within 30-60 minutes or less can save or lose a tooth.
