If it is a baby tooth, do not reinsert the tooth. See your dentist to make sure there is no other damage or pieces embedded in the lips/ cheeks. The baby tooth will not be reinserted.
If you are not sure, or it is an adult tooth, ALWAYS hold the tooth by the crown and NEVER HOLD THE ROOT. Place in a cup of milk or saliva. NEVER WASH WITH WATER AS THIS WILL KILL THE ATTACHED LIGAMENTS.
