Title: Myofascial Pain from Trigger Points in Masticatory Muscles Misleadingly Mimicking Odontogenic Pain: A Case Report

Abstract

Aims: Myofascial pain syndrome (MPS) may result from acute muscle strain or chronic over-use and misuse due to dental misalignment, teeth grinding, teeth clenching, anxiety, or stress. It is believed that the actual site of strain forms a trigger point that induces pain in other areas, which can mimic odontogenic pain and lead to unnecessary treatments. Presentation of Case: Here, we report the case of a 65-year-old woman who suffered from a toothache, which had not been relieved after several dental treatments. We suspected myofascial pain with trigger points in her masticatory muscles. The occlusal interference in posterior teeth on the opposite side of the painful region was adjusted, the masticatory muscles were massaged, and the patient was prescribed with a muscle relaxant. The patient’s pain was significantly relieved and her condition resolved completely afterwards. Conclusion: MPS can present as a non-odontogenic toothache originating from trigger points in masticatory muscles. Therefore, clinicians should avoid irreversible dental procedures before excluding non-odontogenic causes of pain.
