This week in dental tourism #7: the civil suit that shows the legal trap

In January 2023, Luong Thu Nguyet, 29, had 24 porcelain crowns placed at a clinic in Ho Chi Minh City at a cost of VND 144 million [1]. The operator, Nguyen Thi Hoa, 66, was found by the HCMC Department of Health Inspectorate in May 2023 to be practising without a licence, fined VND 80 million, and ordered to return VND 120 million in unlawfully obtained profit [1]. Nguyet sued for VND 344 million in compensation. In August 2025 the People’s Court of Ho Chi Minh City dismissed her claim, finding that she had not proved the procedure caused her gum infection. In the court’s words, no official medical conclusion confirmed that a technical error in the crown procedure caused the infection [1]. The regulator found unlicensed practice. The court found no compensable harm. Both findings are on the record, and they do not contradict each other. That is the trap, and it is this week’s column.

The source note first, because the column’s posture requires it. The case facts here are drawn from reporting of the proceedings, not from a court judgment I can read in the original. I am treating the reported facts (the amounts, the dates, the inspectorate action, the dismissal and its stated reason) as accurate reporting of a real proceeding, and I am telling you that is the basis. The analysis is about what the structure of the outcome means for a cross-border patient, and that analysis does not turn on any disputed detail; it turns on the two findings coexisting, which is the part that is clearly established [1].

The two findings, and why both are true

It is tempting to read “fined for unlicensed practice” and “compensation claim dismissed” as a contradiction, as the system saying the operator was a wrongdoer and then saying she did no wrong. That is not what happened, and understanding why is the whole point.

Unlicensed practice is a regulatory offence. It is established by showing the operator practised without the required licence, full stop. It does not require any patient to have been harmed. The inspectorate fined the operator and clawed back her profit because she was practising without authorisation [1]. That finding is complete on its own facts.

A civil compensation claim is a different object with a different burden. To recover damages, a plaintiff generally has to prove not just that the defendant did something wrong, but that the wrong caused the specific harm for which compensation is sought [2] [4]. The element that does the work, and that defeated this claim, is causation [2]. The court did not find that the crowns were fine, or that the operator was competent, or that the infection did not happen. It found that the plaintiff had not produced the evidence to establish that this procedure caused that infection, to the standard the court required [1] [3]. “No official medical conclusion confirmed that a technical error in the crown procedure caused her gum infection” [1] is a statement about the state of the proof, not a statement about the underlying reality. The reality may be exactly as the plaintiff described it. She still loses, because in a civil claim the burden of proving causation sits on the plaintiff [3], and she did not clear it.

So both findings are true. The operator was unlicensed: proved. The procedure caused the harm: not proved. An enforcement system can catch the bad actor and still leave the patient uncompensated, because the two questions are answered by two different processes with two different burdens, and clearing the first does nothing to clear the second.

Why this is the clearest evidence yet of the enforcement–redress gap

This column and this publication have documented, repeatedly, that the legal architecture a cross-border dental patient encounters is not built to restore them. The cross-border dental liability policy review sets out the architecture for the Australian patient: AHPRA cannot reach the overseas operator, travel insurance excludes the elective treatment, and the destination-country courts are theoretically available and practically a long way from being an efficient remedy. The HCMC case is that argument made concrete, and it is sharper than the architecture alone, because here the patient did everything the architecture appears to invite.

She was, on the facts, the strongest version of the wronged patient. The operator was not merely accused. She was found unlicensed by the regulator and penalised [1]. There was a documented inspectorate finding. There was a profit-clawback order. If a regulatory finding of unlicensed practice were a passport to compensation, this is the case that would have used it. And it did not work, because the regulatory finding is not a passport to compensation. The causation burden is a separate gate, and the medical-evidence trail required to pass it (a documented, contemporaneous, expert-supported chain from the specific procedure to the specific harm) is exactly the trail a patient who is treated in one country and develops the complication in another is least equipped to build [2] [3]. She returned to the United States, where the infection presented and was treated [1]; the evidentiary record was therefore split across jurisdictions, which is the recurring structural problem of cross-border claims that the liability review and the conflict-of-laws point [6] both describe.

The editorial line is the one in the dek, and I will state it without hedging because it is earned by the facts: getting a dentist fined is not the same as getting your money back, and it is not the same as getting your teeth fixed. The enforcement apparatus and the redress apparatus are different machines. Vietnam’s caught the bad actor. It did not restore the patient. A patient who reads “the regulator acted” as “I will be made whole” has misread the architecture, and the misreading is the trap.

The 24-crowns detail, briefly, because it is clinical

I will not pass over the clinical fact buried in the case. Twenty-four porcelain crowns is, in most adult dentitions, close to a full-mouth crown rehabilitation [5]. Whether that volume of crown work was indicated for this patient is not something I can assess from reporting, and I am not going to assess it, because diagnosing a patient I have not examined from a news account is exactly the move the brand voice of this publication forbids. What I can say at the category level is what this publication has said in the Turkey dental overtreatment economics review and the veneers, crowns and composite bonding review: a treatment plan that crowns a large number of teeth at once is a plan that should have a large amount of diagnostic justification behind it, because crowning a tooth is an irreversible reduction of healthy tooth structure, and the threshold for doing it to two dozen teeth should be correspondingly high. An unlicensed operator is, by definition, an operator practising outside the system that is supposed to hold that threshold. The volume of the treatment and the absence of the licence are not unrelated facts.

What would have cleared the bar, and what a patient can do

The useful version of this column is not “the system failed her.” It is “here is the gate, and here is what passing it requires,” because a cross-border patient who understands the causation gate before treatment is a patient who can build the record the gate demands.

The civil gate is causation, proved by the plaintiff [2] [3]. The evidence that clears it, in the standard medical claim, is a contemporaneous, documented, expert-supported chain: a clear pre-treatment baseline; a complete record of what was done, with what materials, by whom; a contemporaneous record of the complication as it presented; and an independent clinical opinion connecting the specific procedure to the specific harm [4]. A patient treated abroad can build pieces of that chain prospectively, before anything goes wrong, when it is cheap and easy, rather than retrospectively, after it has, when it is expensive and often impossible. That is the practical conversion of the cross-border liability review’s five written confirmations into this specific failure mode: the licence verified in writing before booking; the named operator and named materials documented; the treatment record obtained and carried home; and a continuity-of-care appointment booked at home so the complication, if it comes, is documented by a clinician who can write the contemporaneous record the court will later ask for.

None of that guarantees a win. The causation bar is real and a patient can build a good record and still lose. But the plaintiff in this case appears to have had the strongest possible regulatory finding and still failed on causation, and the lesson a patient should take is not despair. It is that the regulatory finding was never the thing that was going to win the civil claim, and the documentation that would have is documentation built around the treatment, not around the regulator.

The line to keep

Vietnam’s enforcement apparatus did its job in the narrow sense: it found an unlicensed operator and penalised her [1]. The same apparatus left the patient with VND 144 million spent, an infection treated across two countries, and a dismissed claim [1]. Hold those two facts together, because they are the architecture. The system that catches the bad actor and the system that restores the patient are not the same system, and in cross-border dental treatment the gap between them is where the patient stands. A fine is a fact about the operator. It is not a remedy for the patient. The patient’s remedy, if there is to be one, is built before the treatment, out of the licence check, the documented plan, the carried-home record, and the appointment booked at home. That unglamorous paperwork is the only part of the trip the patient actually controls, as this column keeps insisting.
