Oversized treatment plans
This is the most concrete risk. A plan that proposes replacing still-salvageable teeth, or devitalising healthy ones to even out the aesthetics, involves a loss of tissue that cannot be reversed.
The warning sign is disproportion between the reason you wrote and what is being proposed. If you started with two teeth to sort out and the plan involves sixteen, ask for it to be justified element by element. A clinical justification always exists when the indication is correct; if none arrives, that is your signal.
A second opinion — even from your own dentist, on the written plan — costs little and clarifies a lot.
Quotes that change on arrival
That a quote is updated after the CBCT scan is normal and often unavoidable: some things are only visible there. What is not normal is for it to change without explanation, or for lines to appear that were never mentioned.
The protection is simple: insist on a written, itemised quote before travelling, with individual lines rather than a single total, and ask explicitly which additional procedures might become necessary and what they would cost. A clinic that works properly has already considered those possibilities.
Timings that are too compressed
Biological timescales are not negotiable. Osseointegration takes months, tissue healing takes its days, and an infection has to be treated before a rehabilitation is built on top of it.
Be wary of proposals promising complex work completed in very few days and a single trip. They are not always improper — immediate-loading protocols exist, with precise indications — but they must be explained, and they must make sense in your specific case rather than being presented as a selling point.
Absent follow-up
The single most frequent problem is not surgery gone wrong: it is the patient who, six weeks later, does not know who to write to. It is also the easiest to prevent, because you can simply ask beforehand.
Concrete question to ask: if I have a symptom after returning, who answers me, in what language, and how quickly? If a check-up appointment is needed, how is it arranged and who bears the clinical cost? The answers should be specific. «Just get in touch» is not an answer.
Incomplete clinical documentation
At the end of treatment you should go home with the documentation: the plan carried out, the radiographs, and — for implant work — the codes and system of the implants placed.
This is not bureaucracy. Without that data, a dentist at home who has to intervene years later is working blind on components they cannot identify, and maintenance becomes far harder than it should be. Ask explicitly what you will be given.
Informed consent: what you are signing
Before any procedure you are asked to sign an informed consent form. It is not a formality to be dispatched quickly in the waiting room: it is the document describing what will be done, what alternatives existed and which complications are possible.
Read it, and insist it is in a language you understand. A consent form in a language you do not command is not informed consent, and it is one of the points where direct communication with the doctor makes a concrete difference.
If the document lists complications that were never mentioned out loud, that is the moment to ask for an explanation, not afterwards. A doctor who has planned the case well has no difficulty discussing them: they are part of the picture, and knowing them in advance is in your interest.
The checklist before you book
Seven questions, every one with a verifiable written answer. If a clinic answers all of them without hesitation, you have already excluded most of the risks in this article.
- Who physically performs the surgery, and with what specialisation?
- Will I speak to that same person at the check-ups?
- Can I have the treatment plan in writing, line by line, before travelling?
- Which additional procedures might be needed, and what would they cost?
- Which implant system is used, and will I receive the component codes?
- How many days do I need to stay, and how many trips are genuinely required?
- After I return home, who answers me and how quickly?
