Medication-Related Osteonecrosis of the Jaw (MRONJ) Care in St Leonards
By: damian@nestdental.com.auUpdated: February 25, 2026
Medication-Related Osteonecrosis of the Jaw (MRONJ) is a rare but serious condition affecting the jawbone. It is associated with certain medications commonly prescribed for osteoporosis, cancer treatment, and bone-related conditions. At Nest Dental, we provide careful assessment, preventive planning, and coordinated management for patients at risk.
What Is MRONJ?
MRONJ occurs when an area of jawbone becomes exposed and fails to heal properly, usually after a dental procedure such as an extraction. The condition is linked to medications that affect bone metabolism and healing. While MRONJ is uncommon, prevention and early detection are critical for patients taking certain bone-modifying medications.
- Osteoporosis
- Bone metastases from cancer
- Multiple myeloma
- Paget's disease of bone
Medications Associated with MRONJ
The most commonly associated medications include:
- Bisphosphonates (oral and intravenous)
- Denosumab
- Certain anti-angiogenic drugs
Signs and Symptoms
If you are taking bone-modifying medications and notice any of the following, seek dental assessment promptly:
- Exposed bone in the mouth that doesn't heal
- Pain, swelling, or infection of the jaw
- Numbness or heaviness in the jaw
- Loose teeth without obvious cause
- Drainage or pus from the gums
Prevention and Management
Prevention is the most important strategy for MRONJ. Our approach includes:
1
Pre-Medication Dental Assessment
If you're about to start bisphosphonates or similar medications, a comprehensive dental check-up beforehand can identify and address issues that might increase your risk.
2
Preventive Dental Care
Regular check-ups, good oral hygiene, and prompt treatment of dental problems reduce the risk of MRONJ developing.
3
Conservative Treatment
When dental treatment is needed, we use conservative, minimally invasive approaches where possible.
4
Coordinated Care
We work closely with your medical team - including oncologists and endocrinologists - to manage your dental care safely.
