This game is the logical companion to Operation. Players require steady hands and strong nerves to extract teeth without making their patient SCREAM!Patients have different numbers of teeth to extract. Side teeth are more difficult than front teeth. A probe and mirror are the only tools to be used. One slip and the patient screams loud and long.The teeth with their specially designed hooks are carefully nudged from behind the patients mouth. Only by using the mirror can you see what you are doing. - BoardGameGeek
