Try to stay calm while you pick up the tooth by its crown (the part that sits above the gumline) and avoid touching the root. Briefly rinse it with cold running water if it’s dirty and try to replant it. Once in place, bite on a piece of fabric to hold it in position. If you’re unable to do this, put the tooth in a glass of milk or saline solution (avoid water!) until you see us. Adults can also put it in their mouth, keeping it between their molars and the inside of the cheek.
