Infection in Lower Jaw Bone Causes, Symptoms, Treatment, and Prevention

Osteomyelitis of the lower jaw bone is a serious medical condition that may require immediate treatment by a dental professional. It occurs when the bone becomes infected as a result of a bacterial invasion, often linked to poorly controlled diabetes, dental procedures, or other health issues that compromise the immune system. This infection can cause significant pain and swelling in the area, and if left untreated, it can spread to other parts of the body, posing a serious risk to health.

Causes of Infection in Lower Jaw Bone

Osteomyelitis of the lower jaw bone can result from a variety of organisms, including aerobic and anaerobic bacteria, such as Staphylococcus aureus and Peptostreptococcus, but in more rare cases, it may involve anaerobic bacteria like Actinomyces species. Trauma, particularly after jaw injuries or after dental extraction, can also lead to bone infection. Additionally, diabetes, which affects the body's ability to fight infection, is a major risk factor for osteomyelitis of the lower jaw bone.

Symptoms of Infection in Lower Jaw Bone

Symptoms of infection in the lower jaw bone can include severe pain, particularly when opening or biting, swelling in the lower face and jaw, fever, and general malaise. As the infection progresses, there may be visible signs such as fluctuation, skin color changes, or pus discharge from the mouth or gums.

Treatment of Infection in Lower Jaw Bone

Treatment of infection in the lower jaw bone typically involves a combination of antibiotics and surgical debridement. An initial course of antibiotics may be given intravenously, but if the infection does not respond to treatment, surgical debridement may be necessary to remove the infected bone and minimize the spread of infection. In some cases, the dentist may also recommend a course of oral抗生素 therapy to control the infection and promote healing of the bone.

Prevention of Infection in Lower Jaw Bone

Preventing infection in the lower jaw bone involves maintaining good oral hygiene, receiving timely dental care after injuries or procedures, and managing conditions that may impact the immune system, such as diabetes. Regular visits to the dentist for check-ups and cleanings can also help prevent jaw infections.


Infection in the lower jaw bone is a serious medical condition that requires timely recognition and treatment. If you are experiencing symptoms of jaw pain, fever, or swelling, it is crucial to seek immediate medical attention. With proper treatment and management, the vast majority of jaw infections can be effectively controlled and cleared, preventing further complications and preserving oral health.
