Jaw ache that doesn’t go away, unfastened enamel or seen bone in your mouth aren’t simply dental issues; they’re warning indicators of a critical underlying situation that impacts how your physique heals. Remedy-related osteonecrosis of the jaw, or MRONJ, is a devastating complication tied to medicine generally prescribed for osteoporosis and cancer-related bone loss. And as soon as the situation begins, reversing the harm is extremely troublesome.
What makes this much more regarding is how broadly these medicines are used, usually with out totally disclosing the long-term dangers. Whereas they’re designed to cease bone breakdown, these medicine additionally block your physique’s pure means to restore itself. Over time, that tradeoff results in infections, fractures, and everlasting lack of jawbone tissue.
In the event you’ve ever been provided a bone drug like denosumab or a bisphosphonate, or when you’re already taking one, you need to know precisely what’s at stake. As a result of this isn’t nearly uncomfortable side effects — it’s about defending your long-term well being and preserving your means to heal.
Jaw Harm Threat Spikes with Bone Medicine and Steroid Use
Revealed in Scientific Experiences, a large-scale Finnish cohort examine adopted 58,367 adults who have been prescribed antiresorptive medicine — primarily bisphosphonates or denosumab — between 2013 and 2015.1
Antiresorptive medicine are medicines designed to decelerate bone loss by blocking the exercise of cells that break down bone tissue; nonetheless, they’re related to critical uncomfortable side effects. Researchers got down to calculate how usually these medicine triggered MRONJ, a situation the place uncovered jawbone does not heal, inflicting persistent ache, an infection or fractures.
• Most contributors have been older ladies taking the medicine for osteoporosis, however most cancers sufferers confronted larger dangers — The typical age was 72, and 82% of the contributors have been ladies. Most have been handled for osteoporosis, however about 13% had a most cancers prognosis. The danger of MRONJ was a lot larger in these utilizing the medicine to handle cancer-related bone loss, notably when medicines got in excessive doses.
• MRONJ charges have been 5 instances larger in denosumab customers than in bisphosphonate customers — Amongst low-dose customers, the danger of MRONJ jumped fivefold when sufferers got denosumab reasonably than bisphosphonates. In high-dose customers, that distinction held regular, with denosumab triggering the situation at roughly 5 instances the speed of bisphosphonates.
• Corticosteroids made the issue worse, multiplying danger sixfold in some instances — For sufferers on low doses of antiresorptive medicine, including corticosteroids elevated the danger of jaw illness by greater than six instances. In these on excessive doses, the added steroid use nonetheless doubled the danger. This mixture seems particularly harmful for individuals utilizing bone medicine preventively, not only for most cancers.
• Males, particularly these with most cancers, had the worst outcomes — Male sufferers on high-dose therapies have been extra more likely to develop MRONJ than ladies. The researchers famous this was very true for males with prostate most cancers. Variations in oral hygiene and life-style may assist clarify the gender hole, as males are inclined to brush much less usually and have worse dental well being total.
Threat Accelerated After 5 Years of Use
The longer sufferers stayed on bone medicines, the extra seemingly they have been to develop jaw necrosis. Excessive-dose customers confirmed a noticeable improve in MRONJ charges after 5 years of steady use.2 That’s particularly alarming contemplating many individuals take these medicine indefinitely.
• Biologically, denosumab halts bone restore too aggressively — Denosumab suppresses a key enzyme that alerts the presence of osteoclasts — cells your physique makes use of to interrupt down previous or broken bone. By almost wiping out this enzyme’s exercise, denosumab leaves the jawbone unable to heal from minor accidents or infections. This excessive suppression of bone turnover seemingly explains the fast onset of MRONJ in comparison with bisphosphonates, which accumulate slowly in bone over time.
• Drug supply methodology additionally mattered; photographs and IVs prompted extra hurt than tablets — Intravenous or subcutaneous supply of antiresorptive medicine resulted in a lot larger danger than oral dosing. How a drug enters your physique modifications how aggressively it interferes with bone reworking.

In low-dose customers, this change greater than doubled the danger. The examine means that stacking these medicines is a mistake.
Prevention Is Your Greatest Protection In opposition to Jaw Harm
Revealed within the Journal of Worldwide Society of Preventive & Group Dentistry, a suggestion paper explored how you can stop and handle MRONJ, notably in individuals receiving antiresorptive or antiangiogenic medicine, that are medicines that cease the physique from making new blood vessels, usually utilized in most cancers remedy.3 The researchers laid out a sensible, step-by-step framework for figuring out danger elements and intervening earlier than critical bone harm happens.
• Most cancers sufferers receiving intravenous remedy have been among the many highest-risk teams — The paper distinguished between osteoporosis sufferers and most cancers sufferers, mentioning that most cancers sufferers present process IV antiresorptive or antiangiogenic remedy want a whole oral examination earlier than beginning remedy. In the event you’re on this class, you’re at excessive danger of experiencing issues, particularly when you’ve had latest dental work, have poor oral hygiene or use detachable dentures.
• Greater than half of MRONJ instances start after tooth extraction — In accordance with the findings, 52% to 61% of MRONJ diagnoses have been triggered by dental surgical procedures, particularly tooth removals. The paper urged dentists and oncologists to stabilize any dental points, like infections or superior gum illness, earlier than a affected person ever begins drug remedy.
Though MRONJ is usually triggered by dental procedures like extractions, it additionally happens with none dental intervention in any respect. Your danger will increase considerably when you’ve been on antiresorptive medicine for greater than two years or have dentures or present gum illness like periodontitis.4
• Your jaw is uniquely weak due to its poor blood provide and fixed microbial publicity — Not like different bones in your physique, your jawbone is skinny, densely packed and regularly injured by chewing, brushing or dental procedures.

These elements intrude together with your physique’s means to regenerate bone and struggle infections, making it a lot more durable to reverse MRONJ as soon as it units in.
• Preventive dental care reduces your danger — The paper emphasised that ongoing dental hygiene and common screenings each 4 to 6 months assist detect jaw issues earlier than they progress. In later levels, procedures grow to be way more invasive, together with partial jawbone removing.

These scans ship inconsistent outcomes and infrequently immediate repeat testing that doesn’t enhance outcomes. Notably, the surge in DEXA suggestions coincided with the rollout of pharmaceutical bone medicine, a sample that raises crimson flags.
As an alternative, I like to recommend a safer and extra exact strategy: Radiofrequency echographic multispectrometry (REMS) know-how. This methodology analyzes uncooked ultrasound alerts to evaluate bone power, supplying you with an in depth image of your fracture danger with out exposing your physique to ionizing radiation.
In accordance with a examine in Diagnostics, REMS outperformed DEXA in a number of methods, making it a better choice when you’re trying to monitor bone well being or consider the results of life-style modifications.6 It’s a greater software to information your selections, particularly when you’re attempting to keep away from pointless medicines.

I like to recommend optimizing your physique’s manufacturing of vitamin D and your consumption of nutritional vitamins K1 and K2, magnesium, calcium, and collagen.
These work collectively to stimulate wholesome bone formation whereas preserving your mineral stability in test. Collagen is very essential — it makes up the versatile framework that minerals construct upon.
4. Prepare your bones safely with blood circulate restriction exercises — In the event you’re older or can’t carry heavy weights, blood circulate restriction (BFR) coaching is a strong different. It really works by briefly limiting blood circulate to your limbs throughout mild train, triggering a development response in muscle tissue and bones. You get the advantages of power coaching with out the pressure. BFR has proven promising results on bone density,7 and it’s secure to do even when you’re frail or recovering.
5. Keep in keeping with each day motion and mineral-rich meals — Your bones reply to your each day habits. Stroll day by day. Get common solar publicity to help vitamin D manufacturing. In the event you’ve been on a weight-reduction plan excessive in linoleic acid (LA), get your solar publicity throughout early morning or late afternoon — as a substitute of peak hours from 10 a.m. to 4 p.m. — to keep away from pores and skin harm.
Eat meals wealthy in magnesium and calcium, like leafy greens, pastured dairy, and slow-simmered bone broth. Keep away from vegetable oils, tender drinks and processed meals, which improve irritation and disrupt mineral absorption. By specializing in nourishment, motion, and prevention, you give your physique the instruments it must rebuild bone safely, with out risking your jaw.
