Like a dentist's office, players will have a number of tools for dental treatment, complete with lights above the patient's face.
A player's task is to examine any problems that exist in the patient's mouth, and use appropriate tools to address them. The first equipment is owned water hoses and sump. The presence of water is needed to solve some problems. There is also a drill, which can be used to repair cavities. (Fixing holes with just a drill? Somewhat unrealistic indeed.)
