Understanding Osteonecrosis
The American College of Rheumatology states that the human body's bone and bone marrow comprise of living cells that require a steady blood supply to stay healthy. If this blood flow decreases significantly, the cells may die and the bone may collapse as a result. This process is known as osteonecrosis, and it can lead to pain and limited use of the affected joints.
According to WebMD, avascular necrosis is "the death of bone tissue due to a lack of blood supply." The condition can occur in almost any bone of the body, but when it affects one's dental health, it typically affects the jawbone. It may lead to minuscule breaks in the bone and, eventually, the bone's total collapse. A broken jawbone or dislocated jaw joint may interrupt how the blood flows to a section of the bone. Like arthritis, osteonecrosis may cause severe pain and disability. However, early diagnosis and treatment may improve the outcome.

Common Causes of Osteonecrosis
Osteonecrosis is associated with glucocorticoid (or corticosteroid) medicine use and excessive alcohol intake. Other common causes include serious trauma, which interrupts the blood supply to the bone, and systemic lupus erythematosus. Reduced blood supply may also be caused by fatty deposits in blood vessels and certain diseases.

Symptoms of Osteonecrosis
According to BreastCancer.org, common signs and symptoms of osteonecrosis of the jaw include:
- Bone becoming visible in the mouth
- Draining
- Gums or sockets that do not heal after dental work
- Loose teeth
- Numbness or a heavy feeling in the jaw
- Pain, swelling, redness, or other signs of infection in the gums
However, it is not uncommon to have no symptoms in the early stages of osteonecrosis. The jawbone may only hurt when there is pressure placed on it and only when the condition worsens. Eventually, the pain will be present regardless of whether any pressure is present. Patients should seek immediate medical attention if they have any persistent pain in the jawbone or jaw joint.

Risk Factors for Osteonecrosis
High-dose corticosteroid usage is a common risk factor for osteonecrosis, as is excessive alcohol intake. Certain medical treatments, such as radiation therapy and organ transplantation, may also contribute. Other, less common risk factors for osteonecrosis include decompression disease, blood disorders, HIV infection, radiation therapy, bisphosphonates, and organ transplants. Decompression disease is also known as the "bends" that sometimes occur after scuba diving.

Osteonecrosis Treatment
Early osteonecrosis symptoms may be eased with medication and therapy. Depending on the patient's unique case, the dentist may recommend nonsteroidal anti-inflammatory drugs (NSAIDs), osteoporosis drugs, cholesterol-lowering drugs, blood thinners, rest, and exercise. It is possible for patients with osteoporosis to develop osteonecrosis of the jaw. In these cases, they typically undergo conservative treatment with rinses, antibiotics, and oral analgesics.
According to the American College of Rheumatology, studies have shown that conservative treatment is effective for these patients, and there are also case reports of teriparatide use in managing osteonecrosis of the jaw. Possible surgical treatment options include bone grafting and bone reshaping.

Frequently Asked Questions
Q. How is osteonecrosis of the jaw diagnosed?
A. Osteonecrosis of the jaw is diagnosed via a clinical evaluation. It is diagnosed when the jaw is exposed. Alternatively, it is diagnosed when any amount of necrotic bone is found in the maxilla or mandible for a minimum of eight weeks.
Q. Is osteonecrosis a progressive disease?
A. Yes. Most types of osteonecrosis are progressive, meaning they will only get worse with time. For that reason, it is imperative to treat the problem at the root instead of merely attacking its symptoms.
Q. How can you prevent osteonecrosis?
A. Some cases of osteonecrosis cannot be prevented. However, the best way to prevent osteonecrosis is to decrease the amount of risk factors. Additionally, patients with facial trauma should seek immediate treatment.
Q. Is osteonecrosis painful?
A. Yes. However, this pain is often not noticeable until the disease has already progressed. For this reason, it is crucial to seek immediate treatment if you suspect you are undergoing osteonecrosis.
Q. Are osteonecrosis and avascular necrosis the same thing?
A. Yes. Osteonecrosis and avascular necrosis are synonymous. They may also sometimes be called aseptic necrosis.
