CRITICAL THINKING QUESTION
A patient comes into the dental office with a swollen right cheek and pressure discomfort in the
same area. She states that one specific tooth is very sensitive to temperature and she is having
difficulty eating on that side of her mouth. She also says that the discomfort started seven days
ago, and the swollen cheek appeared overnight. What procedures are required to diagnose the
problem?
Discussion Guidelines: After discussing the problems that the patient has been having for the past
week, the dentist will need to evaluate the tooth. A visual examination would include evaluating any
