By the age of 12, 33% of boys and 19% of girls have experienced at least one dental trauma. When dental trauma occurs, visiting a dentist is highly recommended. To enhance prognosis of treatment, specially in the case of avulsed tooth (complete displacement of a tooth). avulsed tooth should be replanted as soon as possible. Remember, do not keep tooth by root, take it by crown and if tooth is contaminated, wash it gently in normal saline and replant it in its position and visit a dentist as soon as possible. If you are not sure to do it yourself, put it in special solution (Known as “save a tooth”). If you do not have the solution, put tooth in a normal saline, low fat cold milk, child saliva or even water and see a dentist as soon as possible.
