Osteomyelitis of the jaw on imaging: what to know

Imaging of an infected jaw may show patchy bone destruction, areas of increased density, an irregular outline, or a piece of separated damaged bone. The pattern can vary with the stage and extent of infection. Similar changes can occur with other dental, inflammatory, or healing conditions, so a radiograph is not interpreted in isolation.

Symptoms may include jaw pain, swelling, tenderness, loose teeth, bad taste, drainage, reduced mouth opening, or numbness of the lip or chin. A dentist, oral and maxillofacial surgeon, or medical clinician may combine a dental examination with radiographs, advanced imaging, blood tests, and sampling when appropriate.

Arrange prompt dental or medical assessment for persistent jaw pain, swelling, drainage, or a wound that does not heal after dental treatment. Mention recent extraction, implant, trauma, medication affecting bone, and any fever or immune condition. Keep the mouth clean according to professional advice and do not place unapproved substances on the wound.

Treatment may address the dental source, provide antibiotics when indicated, drain an abscess, and remove unhealthy tissue. If infection has caused a bone defect and reconstruction is needed, a specialist may discuss [Bone Grafting](/treatments/trauma-and-fracture-care/bone-grafting/).

Seek urgent care for rapidly increasing facial or neck swelling, difficulty breathing or swallowing, inability to open the mouth, spreading redness, severe weakness, confusion, or fever with shaking chills. These signs may indicate infection affecting nearby spaces or the airway.

Ask which jaw area is involved, whether the image suggests infection or another process, whether a dental source remains, what sampling or imaging is needed, and how eating and oral hygiene should be managed.
