Earlier this year, as President Donald Trump was beginning to reshape the American government, Michael, an emergency room doctor who was born, raised, and trained in the United States, packed up his family and got out.

Michael now works in a small-town hospital in Canada. KFF Health News and NPR granted him anonymity because of fears he might face reprisal from the Trump administration if he returns to the U.S. He said he feels some guilt that he did not stay to resist the Trump agenda but is assured in his decision to leave. Too much of America has simply grown too comfortable with violence and cruelty, he said.

“Part of being a physician is being kind to people who are in their weakest place,” Michael said. “And I feel like our country is devolving to really step on people who are weak and vulnerable.”

Michael is among a new wave of doctors who are leaving the United States to escape the Trump administration. In the months since Trump was reelected and returned to the White House, American doctors have shown skyrocketing interest in becoming licensed in Canada, where dozens more than normal have already been cleared to practice, according to Canadian licensing officials and recruiting businesses.

The Medical Council of Canada said in an email statement that the number of American doctors creating accounts on physiciansapply.ca, which is “typically the first step” to being licensed in Canada, has increased more than 750% over the past seven months compared with the same time period last year — from 71 applicants to 615. Separately, medical licensing organizations in Canada’s most populous provinces reported a rise in Americans either applying for or receiving Canadian licenses, with at least some doctors disclosing they were moving specifically because of Trump.

“The doctors that we are talking to are embarrassed to say they’re Americans,” said John Philpott, CEO of CanAm Physician Recruiting, which recruits doctors into Canada. “They state that right out of the gate: ‘I have to leave this country. It is not what it used to be.’”

Canada, which has universal publicly funded health care, has long been an option for U.S.-trained doctors seeking an alternative to the American health care system. While it was once more difficult for American doctors to practice in Canada due to discrepancies in medical education standards, Canadian provinces have relaxed some licensing regulations in recent years, and some are expediting licensing for U.S.-trained physicians.

In mere months, the Trump administration has jeopardized the economy with tariffs, ignored court orders and due process, and threatened the sovereignty of U.S. allies, including Canada. The administration has also taken steps that may unnerve doctors specifically, including appointing Robert F. Kennedy Jr. to lead federal health agencies, shifting money away from pandemic preparedness, discouraging gender-affirming care, demonizing fluoride, and supporting deep cuts to Medicaid.

The Trump administration did not provide any comment for this article. When asked to respond to doctors’ leaving the U.S. for Canada, White House spokesperson Kush Desai asked whether KFF Health News knew the precise number of doctors and their “citizenship status,” then provided no further comment. KFF Health News did not have or provide this information.

Philpott, who founded CanAm Physician Recruiting in the 1990s, said the cross-border movement of American and Canadian doctors has for decades ebbed and flowed in reaction to political and economic fluctuations, but that the pull toward Canada has never been as strong as now.

Philpott said CanAm had seen a 65% increase in American doctors looking for Canadian jobs from January to April, and that the company has been contacted by as many as 15 American doctors a day.

Rohini Patel, a CanAm recruiter and doctor, said some consider pay cuts to move quickly.

“They’re ready to move to Canada tomorrow,” she said. “They are not concerned about what their income is.”

The College of Physicians and Surgeons of Ontario, which handles licensing in Canada’s most populous province, said in a statement that it registered 116 U.S.-trained doctors in the first quarter of 2025 — an increase of at least 50% over the prior two quarters. Ontario also received license applications from about 260 U.S.-trained doctors in the first quarter of this year, the organization said.

British Columbia, another populous province, saw a surge of licensure applications from U.S.-trained doctors after Election Day, according to an email statement from the College of Physicians and Surgeons of British Columbia. The statement also said the organization licensed 28 such doctors in the fiscal year that ended in February — triple the total of the prior year.

Quebec’s College of Physicians said applications from U.S.-trained doctors have increased, along with the number of Canadian doctors returning from America to practice within the province, but it did not provide specifics. In a statement, the organization said some applicants were trying to get permitted to practice in Canada “specifically because of the actual presidential administration.”

Michael, the physician who moved to Canada this year, said he had long been wary of what he described as escalating right-ring political rhetoric and unchecked gun violence in the United States, the latter of which he witnessed firsthand during a decade working in American emergency rooms.

Michael said he began considering the move as Trump was running for reelection in 2020. His breaking point came on Jan. 6, 2021, when a violent mob of Trump supporters besieged the U.S. Capitol in an attempt to stop the certification of the election of Joe Biden as president.

“Civil discourse was falling apart,” he said. “I had a conversation with my family about how Biden was going to be a one-term president and we were still headed in a direction of being increasingly radicalized toward the right and an acceptance of vigilantism.”

It then took about a year for Michael to become licensed in Canada, then longer for him to finalize his job and move, he said. While the licensing process was “not difficult,” he said, it did require him to obtain certified documents from his medical school and residency program.

“The process wasn’t any harder than getting your first license in the United States, which is also very bureaucratic,” Michael said. “The difference is, I think most people practicing in the U.S. have got so much administrative fatigue that they don’t want to go through that process again.”

Michael said he now receives near-daily emails or texts from American doctors who are seeking advice about moving to Canada.

This desire to leave has also been striking to Hippocratic Adventures, a small business that helps American doctors practice medicine in other countries.

The company was co-founded by Ashwini Bapat, a Yale-educated doctor who moved to Portugal in 2020 in part because she was “terrified that Trump would win again.” For years, Hippocratic Adventures catered to physicians with wanderlust, guiding them through the bureaucracy of getting licensed in foreign nations or conducting telemedicine from afar, Bapat said.

But after Trump was reelected, customers were no longer seeking grand travels across the globe, Bapat said. Now they were searching for the nearest emergency exit, she said.

“Previously it had been about adventure,” Bapat said. “But the biggest spike that we saw, for sure, hands down, was when Trump won reelection in November. And then Inauguration Day. And basically every single day since then.”

At least one Canadian province is actively marketing itself to American doctors.

Doctors Manitoba, which represents physicians in the rural province that struggles with one of Canada’s worst doctor shortages, launched a recruiting campaign after the election to capitalize on Trump and the rise of far-right politics in the U.S.

The campaign focuses on Florida and North and South Dakota and advertises “zero political interference in physician patient relationship” as a selling point.

Alison Carleton, a family medicine doctor who moved from Iowa to Manitoba in 2017, said she left to escape the daily grind of America’s for-profit health care system and because she was appalled that Trump was elected the first time.

Carleton said she now runs a small-town clinic with low stress, less paperwork, and no fear of burying her patients in medical debt.

She dropped her American citizenship last year.

“People I know have said, ‘You left just in time,’” Carleton said. “I tell people, ‘I know. When are you going to move?’”

Becky Carroll was missing a few teeth, and others were stained or crooked. Ashamed, she smiled with lips pressed closed. Her dentist offered to fix most of her teeth with root canals and crowns, Carroll said, but she was wary of traveling a long road of dental work.

Then Carroll saw a TV commercial for another path: ClearChoice Dental Implant Centers. The company advertises that it can give patients “a new smile in as little as one day” by surgically replacing teeth instead of fixing them.

So Carroll saved and borrowed for the surgery, she said. In an interview and a lawsuit, Carroll said that at a ClearChoice clinic in New Jersey in 2021, she agreed to pay $31,000 to replace all her natural upper teeth with pearly-white prosthetic ones. What came next, Carroll said, was “like a horror movie.”

Carroll alleged that her anesthesia wore off during implant surgery, so she became conscious as her teeth were removed and titanium screws were twisted into her jawbone. Afterward, Carroll’s prosthetic teeth were so misaligned that she was largely unable to chew for more than two years until she could afford corrective surgery at another clinic, according to a sworn deposition from her lawsuit.

ClearChoice has denied Carroll’s claims of malpractice and negligence in court filings and did not respond to requests for comment on the ongoing case.

“I thought implants would be easier, and all at once, so you didn’t have to keep going back to the dentist,” Carroll, 52, said in an interview. “But I should have asked more questions … like, Can they save these teeth?”

Dental implants have been used for more than half a century to surgically replace missing or damaged teeth with artificial duplicates, often with picture-perfect results. While implant dentistry was once the domain of a small group of highly trained dentists and specialists, tens of thousands of dental providers now offer the surgery and place millions of implants each year in the U.S.

Amid this booming industry, some implant experts worry that many dentists are losing sight of dentistry’s fundamental goal of preserving natural teeth and have become too willing to remove teeth to make room for expensive implants, according to a months-long investigation by KFF Health News and CBS News. In interviews, 10 experts said they had each given second opinions to multiple patients who had been recommended for mouths full of implants that the experts ultimately determined were not necessary. Separately, lawsuits filed across the country have alleged that implant patients like Carroll have experienced painful complications that have required corrective surgery, while other lawsuits alleged dentists at some implant clinics have persuaded, pressured, or forced patients to remove teeth unnecessarily.

The experts warn that implants, for a single tooth or an entire mouth, expose patients to costs and surgery complications, plus a new risk of future dental problems with fewer treatment options because their natural teeth are forever gone.

“There are many cases where teeth, they’re perfectly fine, and they’re being removed unnecessarily,” said William Giannobile, dean of the Harvard School of Dental Medicine. “I really hate to say it, but many of them are doing it because these procedures, from a monetary standpoint, they’re much more beneficial to the practitioner.”

Giannobile and nine other experts say they are combating a false public perception that implants are more durable and longer-lasting than natural teeth, which some believe stems in part from advertising on TV and social media. Implants require upkeep, and although they can’t get cavities, studies have shown that patients can be susceptible to infections in the gums and bone around their implants.

“Just because somebody can afford implants doesn’t necessarily mean that they’re a good candidate,” said George Mandelaris, a Chicago-area periodontist and member of the American Academy of Periodontology Board of Trustees. “When an implant has infection, or when an implant has bone loss, an implant dies a much quicker death than do teeth.”

In its simplest form, implant surgery involves extracting a single tooth and replacing it with a metal post that is screwed into the jaw and then affixed with a prosthetic tooth commonly made of porcelain, also known as a crown. Patients can also use “full-arch” or “All-on-4” implants to replace all their upper or lower teeth — or all their teeth.

For this story, KFF Health News and CBS News sought interviews with large dental chains whose clinics offer implant surgery — ClearChoice, Aspen Dental, Affordable Care, and Dental Care Alliance — each of which declined to be interviewed or did not respond to multiple requests for comment. The Association of Dental Support Organizations, which represents these companies and others like them, also declined an interview request.

ClearChoice, which specializes in full-arch implants, did not answer more than two dozen questions submitted in writing. In an emailed statement, the company said full-arch implants “have become a well-accepted standard of care for patients with severe tooth loss and teeth with poor prognosis.”

“The use of full-arch restorations reflects the evolution of modern dentistry, offering patients a solution that restores their ability to eat, speak, and live comfortably — far beyond what traditional dentures can provide,” the company said.

Carroll said she regrets not letting her dentist try to fix her teeth and rushing to ClearChoice for implants.

“Because it was a nightmare,” she said.

‘They Are Not Teeth’

Dental implant surgery can be a godsend for patients with unsalvageable teeth. Several experts said implants can be so transformative that their invention should have contended for a Nobel Prize. And yet, these experts still worry that implants are overused, because it is generally better for patients to have their natural teeth.

Paul Rosen, a Pennsylvania periodontist who said he has worked with implants for more than three decades, said many patients believe a “fallacy” that implants are “bulletproof.”

“You can’t just have an implant placed and go off riding into the sunset,” Rosen said. “In many instances, they need more care than teeth because they are not teeth.”

Generally, a single implant costs a few thousand dollars while full-arch implants cost tens of thousands. Neither procedure is well covered by dental insurance, so many clinics partner with credit companies that offer loans for implant surgeries. At ClearChoice, for example, loans can be as large as $65,000 paid off over 10 years, according to the company’s website.

Despite the price, implants are more popular than ever. Sales increased by more than 6% on average each year since 2010, culminating in more than 3.7 million implants sold in the U.S. in 2022, according to a 2023 report produced by iData Research, a health care market research firm.

Some worry implant dentistry has gone too far. In 10 interviews, dentists and dental specialists with expertise in implants said they had witnessed the overuse of implants firsthand. Each expert said they’d examined multiple patients in recent years who were recommended for full-arch implants by other dentists despite their teeth being treatable with conventional dentistry.

Giannobile, the Harvard dean, said he had given second opinions to “dozens” of patients who were recommended for implants they did not need.

“I see many of these patients now that are coming in and saying, ‘I’ve been seen, and they are telling me to get my entire dentition — all of my teeth — extracted.’ And then I’ll take a look at them and say that we can preserve most of your teeth,” Giannobile said.

Tim Kosinski, who is a representative of the Academy of General Dentistry and said he has placed more than 19,000 implants, said he examines as many as five patients a month who have been recommended for full-arch implants that he deems unnecessary.

“There is a push in the profession to remove teeth that could be saved,” Kosinski said. “But the public isn’t aware.”

Luiz Gonzaga, a periodontist and prosthodontist at the University of Florida, said he, too, had turned away patients who wanted most or all their teeth extracted. Gonzaga said some had received implant recommendations that he considered “an atrocity.”

“You don’t go to the hospital and tell them ‘I broke my finger a couple of times. This is bothering me. Can you please cut my finger off?’ No one will do that,” Gonzaga said. “Why would I extract your tooth because you need a root canal?”

Jaime Lozada, director of an elite dental implant residency program at Loma Linda University, said he’d not only witnessed an increase in dentists extracting “perfectly healthy teeth” but also treated a rash of patients with mouths full of ill-fitting implants that had to be surgically replaced.

Lozada said in August that he’d treated seven such patients in just three months.

“When individuals just make a decision of extracting teeth to make it simple and make money quick, so to speak, that’s where I have a problem,” Lozada said. “And it happens quite often.”

When full-arch implants fail, patients sometimes don’t have enough jawbone left to anchor another set. These patients have little choice but to get implants that reach into cheekbones, said Sohail Saghezchi, an oral and maxillofacial surgeon at the University of California-San Francisco.

“It’s kind of like a last resort,” Saghezchi said. “If those fail, you don’t have anywhere else to go.”

‘It Was Horrendous Dentistry’

Most of the experts interviewed for this article said their rising alarm corresponded with big changes in the availability of dental implants. Implants are now offered by more than 70,000 dental providers nationwide, two-thirds of whom are general dentists, according to the iData Research report.

Dentists are not required to learn how to place implants in dental school, nor are they required to complete implant training before performing the surgery in nearly all states. This year, Oregon started requiring dentists to complete 56 hours of hands-on training before placing any implants. Stephen Prisby, executive director of the Oregon Board of Dentistry, said the requirement — the first and only of its kind in the U.S. — was a response to dozens of investigations in the state into botched surgeries and other implant failures, split evenly between general dentists and specialists.

“I was frankly stunned at how bad some of these dentists were practicing,” Prisby said. “It was horrendous dentistry.”

Many dental clinics that offer implants have consolidated into chains owned by private equity firms that have bought out much of implant dentistry. In health care, private equity investment is sometimes criticized for overtreatment and prioritizing short-term profit over patients.

Private equity firms have spent about $5 billion in recent years to buy large dental chains that offer implants at hundreds of clinics owned by individual dentists and dental specialists. ClearChoice was bought for an estimated $1.1 billion in 2020 by Aspen Dental, which is owned by three private equity firms, according to PitchBook, a research firm focused on the private equity industry. Private equity firms also bought Affordable Care, whose largest clinic brand is Affordable Dentures & Implants, for an estimated $2.7 billion in 2021, according to PitchBook. And the private equity wing of the Abu Dhabi government bought Dental Care Alliance, which offers implants at many of its affiliated clinics, for an estimated $1 billion in 2022, according to PitchBook.

ClearChoice and Aspen Dental each said in email statements that the companies’ private equity owners “do not have influence or control over treatment recommendations.” Both companies said dentists or dental specialists make all clinical decisions.

Private equity deals involving dental practices increased ninefold from 2011 to 2021, according to an American Dental Association study published in August. The study also said investors showed an interest in oral surgery, possibly because of the “high prices” of implants.

“Some argue this is a negative thing,” said Marko Vujicic, vice president of the association’s Health Policy Institute, who co-authored the study. “On the other hand, some would argue that involvement of private equity and outside capital brings economies of scale, it brings efficiency.”

Edwin Zinman, a San Francisco dental malpractice attorney and former periodontist who has filed hundreds of dental lawsuits over four decades, said he believed many of the worst fears about private equity owners had already come true in implant dentistry.

“They’ve sold a lot of [implants], and some of it unnecessarily, and too often done negligently, without having the dentists who are doing it have the necessary training and experience,” Zinman said. “It’s for five simple letters: M-O-N-E-Y.”

Hundreds of Implant Clinics With No Specialists

For this article, journalists from KFF Health News and CBS News analyzed the webpages for more than 1,000 clinics in the nation’s largest private equity-owned dental chains, all of which offer some implants. The analysis found that more than 70% of those clinics listed only general dentists on their websites and did not appear to employ the specialists — oral surgeons, periodontists, or prosthodontists — who traditionally have more training with implants.

Affordable Dentures & Implants listed specialists at fewer than 5% of its more than 400 clinics, according to the analysis. The rest were staffed by general dentists, most of whom did not list credentialing from implant training organizations, according to the analysis.

ClearChoice, on the other hand, employs at least one oral surgeon or prosthodontist at each of its more than 100 centers, according to the analysis. But its new parent company, Aspen Dental, which offers implants in many of its more than 1,100 clinics, does not list any specialists at many of those locations.

Not everyone is worried about private equity in implant dentistry. In interviews arranged by the American Academy of Implant Dentistry, which trains dentists to use implants, two other implant experts did not express concerns about private equity firms.

Brian Jackson, a former academy president and implant specialist in New York, said he believed dentists are too ethical and patients are too smart to be pressured by private equity owners “who will never see a patient.”

Jumoke Adedoyin, a chief clinical officer for Affordable Care, who has placed implants at an Affordable Dentures & Implants clinic in the Atlanta suburbs for 15 years, said she had never felt pressure from above to sell implants.

“I’ve actually felt more pressure sometimes from patients who have gone around and been told they need to take their teeth out,” she said. “They come in and, honestly, taking a look at them, maybe they don’t need to take all their teeth out.”

Still, lawsuits filed across the country have alleged that dentists at implant clinics have extracted patients’ teeth unnecessarily.

For example, in Texas, a patient alleged in a 2020 lawsuit that an Affordable Care dentist removed “every single tooth from her mouth when such was not necessary,” then stuffed her mouth with gauze and left her waiting in the lobby as he and his staff left for lunch. In Maryland, a patient alleged in a 2021 lawsuit that ClearChoice “convinced” her to extract “eight healthy upper teeth,” by “greatly downplay[ing] the risks.” In Florida, a patient alleged in a 2023 lawsuit that ClearChoice provided her with no other treatment options before extracting all her teeth, “which was totally unnecessary.”

ClearChoice and Affordable Care denied wrongdoing in their respective lawsuits, then privately settled out of court with each patient. ClearChoice and Affordable Care did not respond to requests for comment submitted to the companies or attorneys. Lawyers for all three plaintiffs declined to comment on these lawsuits or did not respond to requests for comment.

Fred Goldberg, a Maryland dental malpractice attorney who said he has represented at least six clients who sued ClearChoice, said each of his clients agreed to get implants after meeting with a salesperson — not a dentist.

“Every client I’ve had who has gone to ClearChoice has started off meeting a salesperson and actually signing up to get their financing through ClearChoice before they ever meet with a dentist,” Goldberg said. “You meet with a salesperson who sells you on what they like to present as the best choice, which is almost always that they’re going to take out all your natural teeth.”

Becky Carroll, the ClearChoice patient from New Jersey, told a similar story.

Carroll said in her lawsuit that she met first with a ClearChoice salesperson referred to as a “patient education consultant.” In an interview, Carroll said the salesperson encouraged her to borrow money from family members for the surgery and it was not until after she agreed to a loan and passed a credit check that a ClearChoice dentist peered into her mouth.

“It seems way backwards,” Carroll said. “They just want to know you’re approved before you get to talk to a dentist.”
