Toothache is almost always caused by odontogenic toothache, but diagnosis is more difficult in the case of nonodontogenic toothache. We report a case of simultaneous occurrence of odontogenic and nonodontogenic toothache. This manuscript presents a case report for a 35-year-old woman who visited our Orofacial and Head Pain Clinic with the chief complaint of continuous dull pain in left maxillary molar teeth region. It was concluded to be a case of simultaneous odontogenic toothache and nonodontogenic toothache. It was successfully treated by an endodontist and an orofacial pain specialist. The endodontist performed root canal treatment against odontogenic toothache caused by apical periodontitis using a dental operating microscope. The presence of a trigger point (TP) resulting in tooth pain was inferred. A trigger point injection (TPI) was administered by orofacial pain specialist, and toothache relief was confirmed. Myofascial pain was diagnosed definitively. After confirming that the toothache had resolved at multiple TPIs, a crown prosthesis was placed. Following the application of crown prosthesis, we were concerned but did not find recurrence of toothache from myofascial pain due to increased occlusal force. This case suggests that there is no single cause of chronic pain and that multiple causes must be considered for diagnosis, suggesting the need for treatment by multiple specialists.
