What do I do when a tooth is knocked out?

Immediately call your dentist for an emergency appointment. Handle the tooth by the crown, not the root. Touching the root (the part of the tooth below the gum) can damage cells necessary for bone re-attachment. Gently rinse the tooth in water to remove dirt. Do not scrub. Place the clean tooth in your mouth between the cheek and gum to keep it moist. It is important not to let the tooth dry out. If it is not possible to store the tooth in the mouth of the injured person, wrap the tooth in a clean cloth or gauze and immerse in lukewarm milk or saline solution.
