Tooth loss and osteonecrosis of the jaw are a serious and rare oral complications of herpes zoster infection, particularly in immunocompetent individuals. An immunocompetent 58-year-old male patient presented with a sudden exfoliation of almost all the teeth in his right mandible 2 days prior. Three weeks before this event, he had been diagnosed with herpes zoster infection, which led to irreversible necrosis on the right side of his mandible over 3 months. He was subsequently diagnosed with the osteonecrosis of the right mandible following herpes zoster infection and received aggressive treatment including medication, laser therapy and surgery.
