The horrors of TMJ: Power ache, steel jaws, and futile therapies

A TMJ affected person in Maine had six surgical procedures to switch half or all the joints of her jaw.

One other lady in California, determined for aid, used a screwdriver to elongate her jawbone day by day, turning screws that protruded from her neck.

A 3rd in New York had bone from her rib and fats from her stomach grafted into her jaw joint, and twice a prosthetic eyeball was surgically inserted into the joint as a placeholder within the months it took to make steel hinges to implant into her jaw. 

“I really feel like Mr. Potato Head,” mentioned Jenny Feldman, 50, of New York Metropolis, whose medical data present she’s had a minimum of 24 TMJ-related surgical procedures since she was a teen. “They’re shifting ribs into my face, and eyeballs, and I really feel like a toy … put collectively [by] anyone simply tinkering round.”

These are a few of the horrors of temporomandibular joint issues, often called TMJ or TMD, which afflict as much as 33 million People, based on the Nationwide Institutes of Well being. Dentists have tried to heal TMJ sufferers for near a century, and but the issues stay misunderstood, under-researched, and ineffectively handled, based on an investigation by KFF Well being Information and CBS Information.

Dental look after TMJ can do sufferers extra hurt than good, and some fall right into a spiral of futile surgical procedures that will culminate of their jaw joints being changed with steel hinges, based on medical and dental consultants, sufferers, and their advocates talking in interviews and video testimony submitted to the FDA.

TMJ issues trigger ache and stiffness within the jaw and face that may vary from discomfort to disabling, with extreme signs much more frequent in girls. Dentists have generally handled the dysfunction with splints and orthodontics. And but these therapies are based mostly on “strongly held beliefs” and “insufficient analysis” — not compelling scientific proof nor constant outcomes — based on the Nationwide Academies of Sciences, Engineering and Drugs, which reviewed many years of analysis on the subject. The NIH echoes this message, warning that there’s “not plenty of proof” that splints cut back ache and recommends “staying away” from any therapy that completely adjustments the tooth, chunk, or jaw.

“I might say that the therapies total haven’t been efficient, and I can perceive why,” mentioned Rena D’Souza, director of the NIH’s Nationwide Institute of Dental and Craniofacial Analysis. “We do not perceive the illness.”

For this investigation, journalists with KFF Well being Information and CBS Information interviewed 10 TMJ sufferers with extreme signs who mentioned they felt trapped by an escalating sequence of therapies that started with splints or dental work and grew into a number of surgical procedures with diminishing returns and dwindling hope.

In each interview, the sufferers mentioned the TMJ ache worsened all through their therapy they usually regretted some, if not all, of the care they acquired.

“The grand irony to me is that I went to the physician for complications and neck ache, and I’ve had 13 surgical procedures on my face and jaw, and I nonetheless have even worse neck ache,” mentioned Tricia Kalinowski, 63, of Previous Orchard Seashore, Maine. “And I stay with complications and jaw ache each day.”

TMJ has turn out to be an umbrella time period for about 30 issues that afflict roughly 5% to 10% of People. Minor signs might not require therapy in any respect, and lots of instances resolve by themselves over time. Extreme signs embody persistent ache and will restrict the power to eat, sleep, or discuss.

In a complete research of TMJ issues by the nationwide academies, together with enter from greater than 110 sufferers, consultants discovered that almost all well being care professionals, together with dentists, have acquired “minimal or no coaching” on TMJ issues and sufferers are “usually harmed” by “overly aggressive” care and the shortage of confirmed therapies.

The American Dental Affiliation, which represents about 160,000 dentists nationwide and establishes pointers for the career, declined an interview request. In a written assertion, ADA President Linda Edgar mentioned that TMJ issues are “usually managed slightly than cured” and that it sees “nice potential” in new efforts to analysis extra therapy choices.

Terrie Cowley, a longtime TMJ affected person who leads the TMJ Affiliation, an advocacy group that has spoken with tens of hundreds of sufferers, mentioned she was so disillusioned with dental look after TMJ that she advises many sufferers to keep away from therapy fully, probably for years.

“Virtually 100 years this has been in dentistry, and have a look at what we’ve got,” Cowley mentioned. “An entire ton of individuals pretending they know every thing, and we do not know something.”

“Not taken severely”

Scientific research have discovered that TMJ issues come up as much as 9 occasions as usually in girls, notably these of their 20s and 30s, resulting in theories that the trigger could also be linked to reproductive hormones. However a real understanding of TMJ issues stays elusive.

Kyriacos Athanasiou, a biomedical engineering professor on the College of California-Irvine, mentioned it was as a result of TMJ issues are extra prevalent amongst girls that they had been traditionally dismissed as neither severe nor complicated, slowing analysis into the trigger and therapy.

The ensuing dearth of information, which is obvious in comparison with different joints, has been “an enormous disservice” to sufferers, Athanasiou mentioned. In a 2021 research he co-authored, researchers discovered that the knee, regardless of being a a lot less complicated joint, was the topic of about six occasions as many analysis papers and grants in a single yr than the jaw joint.

D’Souza agreed that TMJ issues had been “not taken severely” for many years, together with different situations that predominantly have an effect on girls.

“That has been a bias that’s actually long-standing,” she mentioned. “And it is definitely affected the progress of analysis.”

Sufferers have felt the impact too. In interviews, feminine sufferers mentioned they felt patronized or trivialized by male well being care suppliers sooner or later of their TMJ therapy, if not all through. Some mentioned they felt blamed for their very own ache as a result of they had been seen as too burdened and clenching their jaw an excessive amount of.

“We desperately want analysis to seek out the the reason why extra girls get TMJ illness,” wrote Lisa Schmidt, a TMJ Affiliation board member, in a 2021 e-newsletter from the group. “And surgeons have to cease blaming this situation on girls.”

Schmidt, 52, of Poway, California, mentioned she was identified with TMJ dysfunction in 2000 as a result of complications, and an orthodontist instantly advisable her for a splint, braces, and surgical procedure.

After sporting the splint for less than three days, Schmidt mentioned, she was in “excruciating ache” and will now not open her mouth far sufficient to eat strong meals. Schmidt mentioned she spent the subsequent 17 years caught on a “surgical procedure carousel” with no escape, and finally was in a lot ache she deserted her profession as an aerospace scientist who labored alongside NASA astronauts.

Schmidt mentioned her low level got here in 2016. In an try to revive bone that had been reduce away in prior surgical procedures, a surgeon implanted lengthy screws into Schmidt’s jaw that protruded downward out of her neck. Schmidt mentioned she was instructed to tighten these screws with a screwdriver day by day for about 20 days, lengthening the corners of her jaw to revive the bone that had been misplaced. It did not work, Schmidt mentioned, and she or he was left in additional ache than ever.

“Each time you have got a surgical procedure, your ache will get worse,” Schmidt mentioned. “If I might return in time and go discuss to youthful Lisa, I might say ‘Run!'”

Lack of ample proof

Lots of the shortcomings of TMJ care had been laid naked within the 426-page report printed by the nationwide academies in March 2020 that acquired restricted public consideration amid the coronavirus pandemic. The report’s 18 authors embody medical and dental consultants from Harvard, Duke, Clemson, Michigan State, and Johns Hopkins universities.

Sean Mackey, a Stanford professor who co-led the staff, mentioned it discovered that sufferers had been usually steered towards expensive therapies and “pathways of futility” as an alternative of being taught to handle their ache by means of methods and therapies with “good proof.”

“We realized it is a quagmire,” Mackey mentioned. “There’s a perverse incentive in our society that pays extra for issues we do to folks than [for] speaking and listening to folks. … A few of these procedures, a few of these surgical procedures, clearly aren’t serving to folks.”

Amongst its many findings, the nationwide academies mentioned it has been extensively assumed within the subject of dentistry that TMJ issues are brought on by a misaligned chunk, so therapies have centered on sufferers’ tooth and chunk for greater than 50 years. However there’s a “notable absence of ample proof” {that a} misaligned chunk is a reason for TMJ issues, and the idea traces again to “insufficient analysis” within the Sixties that has been repeated in “poorly-designed research” ever since, the report states.

Subsequently, TMJ therapy that makes everlasting adjustments to the chunk — like putting in braces or crowns or grinding tooth down — has “no supporting proof,” based on the nationwide academies report. The NIH warns that these TMJ therapies “do not work and will make the issue worse.”

Dental splints, the most typical TMJ therapy, also referred to as evening guards or mouth guards, are detachable dental home equipment which might be molded to suit over the tooth and may value a whole bunch and even hundreds of {dollars} out-of-pocket, based on the TMJ Affiliation. Like most medical gadgets, splints typically undergo the FDA’s 510(okay) clearance course of, which doesn’t require every splint to be confirmed efficient earlier than it may be bought, based on the company.

The nationwide academies’ report states that splints produce “combined outcomes” for TMJ sufferers, and even when splints succeed at decreasing jaw ache it’s not understood why they work. Lots of of splint designs exist, the report states, and a few dentists reject analysis that challenges using splints until it focuses on the precise design they like.

“Due to the a whole bunch of variations in [splint] design, it’s unlikely that any research might ever be performed that will probably be thought-about ample to a selected dentist with a pre-existing perception concerning the effectiveness of 1 equipment,” the report states.

Different therapies fare no higher. The FDA has not labeled any medication particularly for TMJ issues, and ache medicines may be too weak or addictive to be a long-term answer, based on the TMJ Affiliation. Botox injections might ease ache however have raised considerations about bone loss throughout animal testing. The NIH warns that minor surgical procedures that flush the jaw with liquid convey solely non permanent ache aid and that extra complicated surgical procedures ought to be reserved for extreme instances as a result of they’ve but to be proved secure or efficient in the long run.

To enhance care, the nationwide academies referred to as for higher training about TMJ issues throughout drugs and dentistry and extra analysis funding from the NIH, which has a “ripple impact” on analysis and coaching throughout the nation.

For the reason that 2020 report, the NIH has launched a TMJ analysis collaborative and elevated annual analysis funding from about $15 million to about $34 million, D’Souza mentioned. TMJ care was added to the requirements that dental colleges should educate to be accredited in 2022. The nationwide academies launched an ongoing discussion board on TMJ issues final yr.

However TMJ funding nonetheless pales compared to different illnesses. The NIH spends billions every year to analysis lethal ailments, like most cancers and coronary heart illness, that additionally afflict giant numbers of People. It spends thousands and thousands extra on analysis of non-life-threatening situations like arthritis, again ache, eczema, and complications.

Mackey famous that a lot of the NIH’s spending is allotted by Congress.

“If Congress is available in and says, ‘We wish to commit X sum of money to [TMJ],’ all the sudden you will notice a rise in cash,” Mackey mentioned. “In order that’s my message to folks on the market: Elevate your voices. Write your legislator.”

Whole jaw replacements

Stricken by TMJ signs, and after failed therapies, some sufferers flip to a final resort: changing their jaw joint with artificial implants. Surgeons would possibly substitute the cartilage disk on the core of the joint or use “complete joint substitute surgical procedure” to lock a steel hinge to the bones of the cranium.

However the implants have a harrowing historical past: A number of disk implants had been recalled or discontinued within the ’90s as a result of harmful failures. The FDA now classifies TMJ implants amongst its most carefully monitored medical gadgets as a result of the merchandise available on the market right now may cause “antagonistic well being penalties” if the gadgets fail, based on the company’s web site.

Two corporations, Zimmer Biomet and Stryker, make the one complete jaw substitute implants presently bought within the U.S.

Zimmer Biomet, which has made its implant for greater than twenty years, described it in electronic mail statements as “a secure and efficacious answer” for sufferers who want their jaw joint changed, both as a result of TMJ issues, failed surgical procedures, accidents, or different illnesses. An FDA-mandated research accomplished in 2017 discovered about 14% of sufferers who get the Zimmer Biomet implant require further surgical procedure or elimination inside 10 years, mentioned company spokesperson Carly Pflaum.

Stryker, which in 2021 purchased an organization that made a complete jaw substitute implant and now makes the implant itself, declined to remark. Though the NIH has suggested TMJ sufferers to keep away from surgical procedure since a minimum of 2022, Stryker launched a “patient-facing web site” for the implant final yr and is recruiting surgeons to be added to a “surgeon locator” characteristic on the location, based on posts on Fb and LinkedIn.

A research of the Stryker implant’s success charge was mandated by the FDA and accomplished in 2020, however the company has but to make the outcomes public.

D’Souza, the NIH official, mentioned that based mostly on her skilled expertise, she estimates that almost all complete jaw substitute surgical procedures are in the end ineffective.

“The success charge is low,” D’Souza mentioned. “It’s not very encouraging.”

A number of sufferers offered KFF Well being Information and CBS Information with medical data displaying their complete jaw substitute implants needed to be eliminated as a result of malfunction, an infection, or beforehand unknown steel allergy symptoms. A number of sufferers mentioned that since their implants had been eliminated months or years in the past, they’ve lived with no hinge of their jaw in any respect.

Kalinowski, the TMJ affected person in Maine, has had parts of her jaw joint changed six occasions, together with receiving 4 implants. Her medical data present that the cartilage disk on her proper aspect was changed in 1986 with an implant that was later recalled and once more in 1987 with one other that was later discontinued. Her left and proper disks had been changed in 1992 with a muscle flap and rib graft, respectively, and her total proper joint was changed with yet one more implant that was later discontinued in 1998. Each joints had been changed once more in 2015, her data present.

Since then, Kalinowski mentioned, her synthetic jaw has functioned correctly, though she stays in ache and can’t transfer her jaw back and forth. Her mouth hangs open when her face is at relaxation, and she or he drinks protein shakes for lunch as a result of it is simpler than battling strong meals.

However the “worst half,” Kalinowski mentioned, is that her surgical procedures induced nerve harm on her decrease face, and so she has not felt her husband’s kisses because the ’90s.

“If there was one second in my life I might take again and do over once more, it will be that first surgical procedure. As a result of it set me on a trajectory,” Kalinowski mentioned. “And it by no means goes away.”
