Jaw ache that doesn’t go away, free 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. Medicine-related osteonecrosis of the jaw, or MRONJ, is a devastating complication tied to medication generally prescribed for osteoporosis and cancer-related bone loss. And as soon as the situation begins, reversing the injury is extremely troublesome.
What makes this much more regarding is how broadly these drugs are used, usually with out totally disclosing the long-term dangers. Whereas they’re designed to cease bone breakdown, these medication additionally block your physique’s pure potential to restore itself. Over time, that tradeoff results in infections, fractures, and everlasting lack of jawbone tissue.
In the event you’ve ever been supplied a bone drug like denosumab or a bisphosphonate, or should 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 potential to heal.
Jaw Harm Threat Spikes with Bone Medication and Steroid Use
Revealed in Scientific Reviews, a large-scale Finnish cohort research adopted 58,367 adults who had been prescribed antiresorptive medication — primarily bisphosphonates or denosumab — between 2013 and 2015.1
Antiresorptive medication are drugs 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 medication triggered MRONJ, a situation the place uncovered jawbone would not heal, inflicting persistent ache, an infection or fractures.
• Most members had been older girls taking the medication for osteoporosis, however most cancers sufferers confronted increased dangers — The typical age was 72, and 82% of the members had been girls. Most had been handled for osteoporosis, however about 13% had a most cancers prognosis. The danger of MRONJ was a lot increased in these utilizing the medication to handle cancer-related bone loss, notably when drugs got in excessive doses.
• MRONJ charges had been 5 instances increased in denosumab customers than in bisphosphonate customers — Amongst low-dose customers, the danger of MRONJ jumped fivefold when sufferers got denosumab relatively 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 circumstances — For sufferers on low doses of antiresorptive medication, 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 mix seems particularly harmful for individuals utilizing bone medication preventively, not only for most cancers.
• Males, particularly these with most cancers, had the worst outcomes — Male sufferers on high-dose therapies had been extra prone to develop MRONJ than girls. 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 drugs, the extra probably they had been to develop jaw necrosis. Excessive-dose customers confirmed a noticeable enhance in MRONJ charges after 5 years of steady use.2 That’s particularly alarming contemplating many individuals take these medication indefinitely.
• Biologically, denosumab halts bone restore too aggressively — Denosumab suppresses a key enzyme that indicators 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 probably explains the speedy onset of MRONJ in comparison with bisphosphonates, which accumulate slowly in bone over time.
• Drug supply methodology additionally mattered; pictures and IVs brought on extra hurt than capsules — Intravenous or subcutaneous supply of antiresorptive medication resulted in a lot increased danger than oral dosing. How a drug enters your physique adjustments how aggressively it interferes with bone reworking.
• Threat jumped dramatically when sufferers switched from one drug to a different — Individuals who had been first prescribed bisphosphonates and later given denosumab had been extra prone to develop MRONJ than those that stayed on a single drug. In low-dose customers, this swap greater than doubled the danger. The research means that stacking these drugs is a mistake.
Prevention Is Your Finest Protection In opposition to Jaw Harm
Revealed within the Journal of Worldwide Society of Preventive & Neighborhood Dentistry, a tenet paper explored learn how to forestall and handle MRONJ, notably in individuals receiving antiresorptive or antiangiogenic medication, that are drugs that cease the physique from making new blood vessels, usually utilized in most cancers therapy.3 The researchers laid out a sensible, step-by-step framework for figuring out danger elements and intervening earlier than critical bone injury happens.
• Most cancers sufferers receiving intravenous therapy had been among the many highest-risk teams — The paper distinguished between osteoporosis sufferers and most cancers sufferers, declaring that most cancers sufferers present process IV antiresorptive or antiangiogenic therapy want a whole oral examination earlier than beginning remedy. In the event you’re on this class, you’re at excessive danger of experiencing problems, particularly should you’ve had latest dental work, have poor oral hygiene or use detachable dentures.
• Greater than half of MRONJ circumstances start after tooth extraction — In line with the findings, 52% to 61% of MRONJ diagnoses had 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.
Regardless that MRONJ is commonly triggered by dental procedures like extractions, it additionally happens with none dental intervention in any respect. Your danger will increase considerably should you’ve been on antiresorptive medication for greater than two years or have dentures or present gum illness like periodontitis.4
• Your jaw is uniquely susceptible due to its poor blood provide and fixed microbial publicity — In contrast to different bones in your physique, your jawbone is skinny, densely packed and continuously injured by chewing, brushing or dental procedures. The paper defined that lowered blood movement, excessive bacterial load from the mouth, and ongoing put on and tear create an ideal storm. As soon as the bone is uncovered, it struggles to heal below the results of bone-suppressing medication.
• Vitamin D deficiency, native an infection and immune suppression all worsen outcomes — A number of danger amplifiers had been outlined, together with low vitamin D ranges, persistent irritation within the mouth and chemotherapy-induced immune dysfunction. These elements intrude along with your physique’s potential 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 turn into way more invasive, together with partial jawbone removing.
Keep away from Bone Medicines as Safer Bone Choices Exist

However these medication don’t simply sluggish bone loss — they shut down your physique’s pure restore system. And when you add steroids into the combo, your danger of everlasting jaw injury climbs even increased.
Fortuitously, there are higher methods to assist bone power with out risking MRONJ. Whether or not you’re already on these medication or simply contemplating them, it’s not too late to make smarter, safer decisions.

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 medication, a sample that raises crimson flags.
As a substitute, I like to recommend a safer and extra exact method: Radiofrequency echographic multispectrometry (REMS) expertise. This methodology analyzes uncooked ultrasound indicators to evaluate bone power, supplying you with an in depth image of your fracture danger with out exposing your physique to ionizing radiation.
In line with a research in Diagnostics, REMS outperformed DEXA in a number of methods, making it a better choice should you’re seeking to monitor bone well being or consider the results of life-style adjustments.6 It’s a greater device to information your selections, particularly should you’re attempting to keep away from pointless drugs.
3. Rebuild your bones from the within out with focused vitamins — Your bones aren’t simply calcium — they want a full spectrum of vitamins to develop robust and keep resilient. 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 holding your mineral steadiness in examine. Collagen is particularly vital — it makes up the versatile framework that minerals construct upon.
4. Practice your bones safely with blood movement restriction exercises — In the event you’re older or can’t elevate heavy weights, blood movement restriction (BFR) coaching is a strong various. It really works by briefly limiting blood movement to your limbs throughout gentle train, triggering a progress response in muscular tissues 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 protected to do even should you’re frail or recovering.
5. Keep in step with day by day motion and mineral-rich meals — Your bones reply to your day by day habits. Stroll each day. Get common solar publicity to assist vitamin D manufacturing. In the event you’ve been on a weight loss program excessive in linoleic acid (LA), get your solar publicity throughout early morning or late afternoon — as an alternative of peak hours from 10 a.m. to 4 p.m. — to keep away from pores and skin injury.
Eat meals wealthy in magnesium and calcium, like leafy greens, pastured dairy, and slow-simmered bone broth.
