The most important thing to do is to remain calm. Find the tooth and do your best to hold it by the crown rather than the root. You may gently rinse the tooth with saline or milk to remove any debris, being careful to only touch the crown with your fingers. NOTE: Do not rinse the tooth with water. If the entire root is still intact, try to reinsert it in the socket. If that is not possible, put the tooth in a glass of milk and take your child and the glass immediately to your pediatric dentist. Please note that baby teeth are generally not reinserted in the socket due to the risk of damage to the developing permanent tooth beneath it, however your child should still be seen by your pediatric dentist promptly.
