Retrieve the tooth, hold it by the crown (the part that is usually exposed in the mouth), and rinse off the tooth root with water if it’s dirty. If possible, try to put the tooth back in place. Make sure it’s facing the right way. Do not force it back in.
If it is not possible to reinsert the tooth in the socket, put the tooth in a small container of milk (if milk is not available, use a cup of water with a little table salt)
Call us immediately. The sooner the better to have a chance of the tooth being successfully re-implanted
