A 55-year-old woman presented with left facial pain and was diagnosed with MSEO originating from the left upper first molar. Despite undergoing nonsurgical root canal treatment, there was no evidence of bony healing after 6 months. However, cone-beam computed tomographic (CBCT) scans revealed the reestablishment of MSF.
