Understanding Osteonecrosis of the Jaw
Posted on 7/1/2024 by Dr. Anna Grace Clayton |
 Osteonecrosis of the jaw, also known as ONJ, is a serious condition that can affect the jawbone. It occurs when the bone tissue dies, leading to pain, infection, and even bone exposure. While it can be frightening, understanding ONJ and its causes can help you make informed choices about your oral health.
What Causes ONJ?
Several factors can contribute to ONJ, including:
| • |
Medications: Bisphosphonates and denosumab, used to treat osteoporosis and some cancers, can suppress bone turnover, increasing the risk of ONJ. |
| • |
Dental procedures: Invasive dental procedures like tooth extractions or implants can trigger ONJ, especially in patients taking bisphosphonates. |
| • |
Other factors: Diabetes, smoking, and poor oral hygiene can also increase the risk of ONJ. |
Symptoms of ONJ:
ONJ can present with various symptoms, including:
| • |
Jaw pain and swelling |
| • |
Exposed bone in the mouth |
| • |
Loose teeth |
| • |
Numbness or tingling in the jaw |
| • |
Drainage from the jaw |
Diagnosing ONJ:
If you experience any of these symptoms, it's crucial to consult your dentist immediately. They will perform a thorough examination, including X-rays and possibly a biopsy, to confirm the diagnosis.
Treating ONJ:
The treatment for ONJ depends on its severity and the underlying cause. In some cases, simply stopping the medication that triggered ONJ may be enough. However, more severe cases may require surgery, antibiotics, or other interventions.
Minimizing the Risk of ONJ:
Several things can be done to minimize your risk of developing ONJ:
| • |
Talk to your doctor: If you're taking medications that increase your risk of ONJ, discuss this with your doctor. They may recommend alternative medications or adjust your dosage. |
| • |
Maintain good oral hygiene: Brushing twice daily, flossing regularly, and visiting your dentist for checkups and cleanings are essential for preventing oral infections that can contribute to ONJ. |
| • |
Inform your dentist about your medications: Before undergoing any dental procedures, inform your dentist about all medications you're taking, including bisphosphonates and denosumab. This will help them take necessary precautions to minimize the risk of ONJ. |
Restoration Dentistry and ONJ:
Patients with ONJ may require restoration dentistry procedures to address bone loss and improve function. This may involve bone grafts, dental implants, or other reconstructive techniques.
Understanding ONJ and its risk factors can help you make informed decisions about your oral health. By working closely with your dentist and taking preventive measures, you can minimize your risk of developing this serious condition. Early detection and treatment are crucial for managing ONJ and maintaining your oral health. |
