- Jaw Fracture: A break in the jawbone can cause pain and clicking, and is often accompanied by swelling and difficulty moving the jaw.
- Osteonecrosis of the Jaw: A condition in which the jawbone dies due to lack of blood supply, often associated with bisphosphonate use or radiation therapy.
- Parotid Gland Tumors: Tumors of the parotid gland, which is located near the jaw, can cause pain and clicking.
