Honest risks of dental treatment in Vietnam

Dental tourism is a genuine option for hundreds of thousands of patients every year — but it carries real trade-offs that deserve honest documentation. This page does not exist to reassure you; it exists to inform you. If the risks described here give you pause, that is appropriate. The decision to travel for dental care should follow careful thought, not a late-night booking impulse.

Why we publish this page

Most dental tourism websites do not describe what can go wrong. That silence is itself a warning sign. Picasso Dental Clinic publishes this page because patients who understand the risk landscape make better decisions — about whether to travel, when to travel, which clinic to choose, and how to protect themselves if complications arise. An informed patient is also a better post-treatment patient: they monitor their recovery, seek help promptly, and avoid the delays that turn manageable complications into serious ones.

We are aware that publishing frank risk information will discourage some enquiries. We accept that. Patients who proceed after reading this page are proceeding with genuine informed consent — and that is the only basis on which we want to operate.

Clinical risks — what can actually go wrong

Infection and peri-implantitis

Bacterial infection is a risk after any oral surgery — extractions, implant placement, gum surgery, and complex crown preparations all create entry points for oral bacteria. In the immediate post-operative period (days one to five), the risk is acute localised infection. Longer term, implants are susceptible to peri-implantitis, a bacterial infection of the tissues surrounding the implant fixture that, if untreated, destroys the bone holding the implant in place. Warning signs include persistent swelling, bleeding on gentle probing around the implant, bad taste, or visible recession of gum tissue around the implant neck. If you notice any of these more than a few weeks after treatment, see a New Zealand dentist for assessment and notify Picasso at the same time. Early intervention with professional cleaning and sometimes antibiotics can arrest peri-implantitis; ignored, it leads to implant loss.

Nerve injury from aggressive preparation

Preparing teeth for veneers or crowns requires removing tooth structure. When preparation is too aggressive — taking more enamel than the case requires — it risks exposing or irritating the dental pulp and can encroach on the inferior alveolar nerve in the lower jaw. Symptoms include prolonged sensitivity to cold, shooting pain, numbness or tingling in the lip or chin, or a dull ache that does not resolve over weeks. Conservative preparation protocols reduce this risk significantly: Picasso’s veneer work targets 0.3–0.5 mm enamel reduction. But if your existing teeth have large fillings, significant decay, or compromised pulps, the risk is higher and should be discussed before treatment. A tooth that becomes symptomatic after preparation may need root canal therapy; if the nerve is irreversibly damaged, this cannot always be predicted in advance.

Failed osseointegration

Osseointegration — the process by which a titanium implant bonds to living jawbone — takes three to six months for conventional implants. During this period the implant can fail to integrate. Risk factors include heavy smoking, uncontrolled diabetes, low bone density, taking bisphosphonate medications (used for osteoporosis), recent radiotherapy to the jaw, and placing too much load on the implant too soon. Warning signs include pain when biting on the implant, visible movement of the fixture, or persistent swelling months after placement. Picasso uses CBCT 3D scanning to assess bone volume and density before surgery, and will advise against implant placement where bone quality is unsuitable. Implant brands used — Osstem, ETK, Neodent, SIC, Nobel Biocare, Straumann, and Straumann BLX — are all well-documented in the peer-reviewed literature. Brand documentation is available at /safety/implant-brands/. If an implant fails, it requires removal, a healing period, and a separate replacement procedure — which involves additional cost and another trip.

Provisional breakage during long-haul transit

Temporary crowns and veneer provisionals are functional restorations, but they are not as durable as the final ceramics. Long flights involve changes in cabin pressure, dehydration (which dries the oral mucosa and can slightly loosen cementation), and awkward meal choices on aircraft. A temporary crown that debonds during a 12-hour flight home is not a medical emergency, but it is stressful and requires same-day attention on landing. Picasso supplies written aftercare guidance including emergency contact details and, for complex cases, spare temporary cement — but patients should not eat on the affected side during transit and should avoid hard, sticky, or chewy foods for the duration of travel.

Allergy or material reaction

Rare but documented: some patients have reactions to metal alloys in porcelain-fused-to-metal crowns, to nickel in certain base-metal frameworks, or to eugenol-based cements. Symptoms include persistent gum irritation or swelling localised to a specific restoration, contact dermatitis around the mouth, or ongoing sensitivity that does not correlate with the preparation depth. A thorough pre-treatment medical history is the primary screen. If you have known metal allergies or sensitivities, declare them explicitly and discuss material selection — zirconia and full-ceramic restorations eliminate most metal-allergy concerns.

Anaesthetic complications for complex cases

Local anaesthetic is used for virtually all dental procedures and has an extremely strong safety record when administered to healthy adults in the correct dose. Complications — including allergic reactions, intravascular injection, or toxicity from excessive dose — are rare but are more likely in patients with cardiovascular disease, liver impairment, or allergy to amide-type anaesthetics. Complex full-arch cases (All-on-4, All-on-6) may involve larger volumes of local anaesthetic over an extended surgical session. If you have cardiac disease, a history of anaesthetic reactions, or any systemic condition that affects drug metabolism, Picasso requires a GP medical fitness letter before undertaking complex surgery. Details are at /nz-guide/gp-medical-fitness-letter/.

Travel risks — the flight-and-recovery window

Deep vein thrombosis. Oral surgery increases clotting factors temporarily, and long-haul flights carry a low but real DVT risk for all passengers. The combination is not dramatic, but it warrants care. Get up and walk the cabin every hour, stay well hydrated, avoid alcohol, and wear compression socks if your surgeon or GP advises. Patients with a personal or family history of clotting disorders should discuss timing and prophylaxis with their GP before booking.

Dehydration and dry socket. Aircraft cabins maintain low humidity. After extractions or bone grafting, dehydration dries the blood clot in the socket, raising the risk of dry socket — a painful condition where the clot is lost prematurely and the bone underneath is exposed. Drink water consistently throughout the flight, avoid alcohol, and do not smoke. Dry socket is not dangerous but is genuinely painful and requires treatment, typically with medicated dressing placed by a dentist.

Lost or damaged temporaries in transit. Provisionals are vulnerable to baggage-handling vibration and temperature extremes if accidentally stored in checked luggage (they should always travel in your carry-on). A debonded temporary exposes the prepared tooth surface to bacteria and temperature, risks sensitivity, and may be painful. If you have multiple temporaries — as in a full-smile case — the stakes are higher. Pack aftercare materials and the Picasso emergency contact number in your hand luggage.

Cancelled return while still in provisionals. Airline disruptions happen. If you are delayed in Vietnam while wearing temporaries, contact Picasso immediately — your nearest branch can assess and, where possible, re-cement or protect provisionals until you can travel. Build at least two buffer days into your itinerary; do not book the last possible flight before a work commitment.

Swelling and jet lag compounding recovery. Post-surgical swelling typically peaks 48–72 hours after the procedure. Jet lag disrupts sleep, which is when the body does its repair work. Flying home the day after surgery means arriving in New Zealand at the peak of swelling and sleep-deprived. Whenever clinically possible, Picasso schedules final appointments to allow patients at least one full rest day in Vietnam before departure.

Financial risks — protecting your NZD investment

Quote changes on arrival. A remote quote is based on what can be assessed from photographs and supplied X-rays. In-chair examination sometimes reveals additional decay, existing restorations that need removal, or bone loss that changes the treatment scope. At Picasso, any scope change is discussed before treatment begins — you are never presented with an inflated bill at the end. But you should budget a 10–15% contingency for cases where remote records are incomplete. Request a written quote before committing to a deposit, and ask explicitly what additional findings would change the price.

No warranty from low-quality clinics. Many dental tourism clinics offer no written warranty. Some offer a warranty in local currency, with claims processes that require in-person attendance in Vietnam — effectively unenforceable from New Zealand. Picasso’s SmileCare warranty is documented in English with a coordinator-managed claims process. See the full terms at /warranty/.

The cost of fixing bad work elsewhere. Remedial dentistry after poorly performed overseas treatment is one of the most expensive categories of dental work. Replacing a poorly fitted implant requires removal, bone grafting (to replace the bone destroyed by the failed procedure), a healing period, and a new implant — often NZD 8,000–15,000 per site in New Zealand. Replacing a full set of crowns or veneers that are the wrong shade, wrong fit, or causing bite problems can exceed NZD 20,000. In some cases the honest answer is that previous work cannot be corrected — it has to be rebuilt from scratch. Choosing a clinic on price alone, without checking warranty terms, material documentation, and credentials, transfers that financial risk entirely to you.

Psychological risks and realistic expectations

Dental treatment is visible. Unlike a hip replacement, you cannot avoid seeing and showing the result multiple times every day. Shade selection in particular involves genuine subjectivity — what looks natural to the treating dentist may look too white, too opaque, or too bright to you, your partner, or your colleagues. Pre-treatment shade communication using shade guides, photographs, and explicit written agreement on the target is essential.

Expect a period of adjustment. New veneers or a full-arch bridge will feel unfamiliar — you may notice heightened awareness of your bite, altered speech sounds, or sensitivity to temperature for days or weeks. This is normal and typically resolves as the brain recalibrates. It is not a sign of failure.

Family and social environment matter more than patients expect. Some people face criticism from partners or family members who viewed overseas dental treatment as unnecessary or vain, and this criticism lands harder when you are in the adjustment period and not yet loving the result. Being clear — with yourself and your support network — about why you made this decision before you travel reduces this friction significantly.

If anxiety about your treatment outcome persists beyond the normal adjustment window, or if you experience intrusive thoughts or sleep disruption related to the result, these are worth discussing with your GP or a counsellor. Dental-related anxiety and appearance-related anxiety are recognised psychological presentations, and support is available.

When Picasso may decline treatment

Declining a case is sometimes the most clinically responsible decision. Picasso may decline treatment or recommend deferral where:

• Expectations exceed what dentistry can deliver. If a patient’s stated goal cannot be achieved by the tooth morphology, gum position, or facial structure they have, operating to get close only produces disappointment.
• Active uncontrolled disease is present. Uncontrolled diabetes, active periodontal disease, or a current oral infection make implant placement or complex surgical work inadvisable until the underlying condition is managed.
• Systemic health conditions increase surgical risk materially. This includes recent cardiac events, uncontrolled blood pressure, blood thinners that cannot safely be paused, or conditions affecting bone metabolism.
• Insufficient time in-country for the case complexity. Some cases — particularly full-arch reconstructions, cases requiring bone grafting before implant placement, or patients with complex occlusal problems — cannot be safely completed in a standard one- to two-week visit.
• Drug or alcohol use affecting healing. Heavy smoking reduces implant success rates substantially. Current substance use that impairs healing or compliance with aftercare is a contraindication to elective surgery.

A declined treatment is not a failure — it is a protection for you.

When to stay in New Zealand instead

Be honest with yourself about whether overseas treatment is the right choice:

• Your total treatment cost is under NZD 4,000. After flights and accommodation, the financial case is marginal or non-existent for small cases.
• Your dental work was funded by ACC. Injury-related dental treatment funded under the Accident Compensation Corporation should be completed through that pathway in New Zealand.
• You have an active infection that needs urgent treatment. Flying with an active dental infection is dangerous. Treat it first, at home.
• You are pregnant. Elective dental procedures beyond essential care are generally deferred until after delivery.
• You are immunocompromised — due to chemotherapy, immune-suppressing medication, or an immune condition — and surgical risk is materially elevated.
• You have untreated systemic disease that your GP has not cleared for elective surgery.
• You are not comfortable travelling alone or managing your own recovery in an unfamiliar city.

There is no shame in the conclusion that overseas treatment is not right for you. A good New Zealand dentist is a better outcome than a difficult overseas experience.

How Picasso reduces each risk

This is not a list of reassurances — it is a description of specific practices that address the risks documented above.

Pre-treatment assessment. Every implant case begins with CBCT 3D imaging to assess bone volume, density, and proximity to nerves. Veneer cases begin with digital shade matching and a written shade record. Cases with systemic health complexity require a GP medical fitness letter before surgery is scheduled.

Material traceability. Every implant placed at Picasso has a corresponding implant passport documenting the brand, model, lot number, and date of placement. This document is yours to keep and is essential if you ever need a New Zealand dentist or specialist to work on the implant. Crown and veneer ceramics are documented with shade records and prosthetic spec sheets.

Sterilisation standards. Instrument sterilisation at Picasso follows protocols consistent with international dental standards. Documentation is available at /safety/sterilisation-standards/.

Aftercare follow-up. Your coordinator follows up at 24 hours, 48 hours, and one week after treatment. You are not discharged and left without contact. If you raise a concern, it is triaged by the clinical team — not by an administrative team reading from a script.

Warranty coverage. Emax veneers: 7-year warranty. Lava and Lava Plus crowns: 10-year warranty. Composites: 6-month warranty. SmileCare terms are in writing and coordinator-managed. See /warranty/ and /safety/what-if-something-goes-wrong/.

What to do before you fly — your risk-reduction checklist

Working through this list before booking significantly reduces your exposure to the risks described above.

• Get an up-to-date OPG X-ray from your New Zealand dentist and share it with Picasso before your written quote.
• Declare your full medical history — all medications (including supplements), allergies, and systemic conditions — in your initial enquiry. Withholding this information transfers risk to you.
• If your case involves surgery and you have any cardiovascular, metabolic, or immune-system condition, book a pre-travel appointment with your GP and obtain written medical clearance. See /nz-guide/gp-medical-fitness-letter/.
• Arrange travel insurance that includes dental emergency cover and medical repatriation. Read /nz-guide/travel-insurance-dental/ before purchasing a policy.
• Read /is-it-safe/ and /safety/implant-brands/ in full.
• Request a written treatment plan and quote — including material specifications, brand names, and warranty terms — before paying any deposit.
• Build at least two buffer days into your itinerary after your final appointment.
• Save the Picasso emergency contact (email [email protected]) to your phone before you travel.
• Know what to do if something goes wrong: read /safety/what-if-something-goes-wrong/ before you fly.
