Orange oil (isoparaffin C11-C15) is a solvent material that dissolves tooth filling materials effectively. A 29-year-old male who had extensive subcutaneous left temporal necrosis after an in-advertent orange oil injection is presented. Due to the injection, an immediate oedema and cellulitis formed in the left buccal, zygomatic, and temporal region. After a prompt drainage and antibiotherapy, the patient's complaints were resolved. Due to partial temporal muscle necrosis and fibrosis, the interincisal mouth opening (IIO) was 15 millimeters. With a precise physical medicine and rehabilitation regimen, the IIO became 35 millimeters at the postoperative first year.
