GP medical fitness letter for dental surgery in Vietnam — when Australians need one
When Australians need a GP fitness letter for dental treatment in Vietnam, what it should state, and why blood thinners and bisphosphonates must be disclosed to the clinic early.
A GP medical fitness letter matters mainly for implant, All-on-4, or full-mouth surgical cases, and for patients with medical conditions or on blood thinners. For simple veneers or crowns it is usually not required. Either way, the part that actually changes your treatment is disclosing your medications and conditions to the clinic before you travel — so the plan is built around them, not adjusted on the day.
If you are having simple cosmetic work — veneers, a few crowns — you almost certainly do not need a GP fitness letter, and nobody should make you feel otherwise.
It matters for two groups: people having surgery (implants, All-on-4, full-mouth work), and people with a medical condition that affects how they handle treatment. If neither applies to you, you can skip most of this page.
Letter usually needed vs usually not needed
| Letter usually needed | Letter usually not needed |
|---|---|
| Dental implants | Single veneer or a few cosmetic veneers |
| All-on-4 / full-arch | One or two simple crowns |
| Full-mouth rehabilitation | Routine clean and check |
| Heart conditions | Whitening |
| Diabetes (especially poorly controlled) | A healthy patient having minor cosmetic work |
| On blood thinners / anticoagulants | — |
| On bisphosphonates | — |
| Immunosuppression | — |
| Pregnancy | — |
The pattern is simple: surgery plus medical complexity means get the letter; routine cosmetic work on a healthy patient means you generally do not need one.
What the letter should contain
Ask your GP to include, on one page:
- Your current medications — names and doses
- Relevant medical history — heart conditions, diabetes, anything that affects surgery or healing
- Allergies — especially to medications, latex, or anaesthetic
- Blood-thinner / anticoagulant status — which medication, and any management plan agreed for surgery
- A plain statement of fitness to travel and to undergo dental treatment
That is enough. The clinic does not need your whole file — it needs the facts that change the treatment plan.
Blood thinners and bisphosphonates — disclose these early
This is the part to read twice.
If you take a blood thinner — warfarin, apixaban, rivaroxaban, dabigatran, clopidogrel, or similar — tell the clinic before you travel, not on the day. These affect bleeding during surgery and healing afterwards, and the treating dentist may need a management plan worked out with your GP first.
If you take or have taken bisphosphonates (for osteoporosis or bone conditions), disclose this too. They carry a risk of MRONJ — a jaw-healing complication after dental surgery — and the clinic must know in advance to plan safely.
Send your current medication list to the clinic before you fly, along with the GP letter if you have one and any recent relevant test results. The point of doing it early is that the treatment plan gets built around your situation from the start, rather than being changed once you are sitting in the chair.
A quick word on what this page is
This is general information to help you organise yourself before you travel. It is not medical advice. Your Australian GP and the treating dentist make the call on whether you are fit for treatment — this page just helps you have the right conversation and bring the right paperwork.
If something goes wrong while you are still in Australia, the emergency number is 000.

Frequently asked questions
Do I need a GP fitness letter for dental work in Vietnam?
Often not. For simple cosmetic veneers and crowns, a fitness letter is usually not required. It becomes relevant for surgical cases — implants, All-on-4, full-mouth work — or if you have a medical condition such as a heart condition, diabetes, or you take blood thinners or bisphosphonates. If you are unsure, ask the clinic when you send your case, and they will tell you whether one is worth getting.
When is a GP fitness letter actually required?
Two situations. First, surgical treatment — dental implants, All-on-4, or full-mouth rehabilitation. Second, any patient with a relevant medical condition: heart conditions, poorly controlled diabetes, immunosuppression, pregnancy, or anyone on anticoagulants or bisphosphonates. In those cases the letter confirms you are fit to undergo treatment and to travel, and gives the treating dentist the medical context they need.
What should the letter say?
It should list your current medications, relevant medical history, allergies, and your blood-thinner or anticoagulant status with any management plan. It should end with a plain statement that you are fit to travel and to undergo dental treatment. Keep it to one page — the clinic needs the facts, not a full medical file.
What if I am on blood thinners?
Disclose it before you travel — this is the one thing you must not leave until the appointment. Warfarin, apixaban, and similar anticoagulants affect bleeding and healing, and the clinic may need a management plan agreed with your GP before any surgery. Send your medication list early so the treatment plan accounts for it from the start.
Will my GP charge for the letter?
Usually yes. Writing a fitness-for-treatment letter is not a standard bulk-billed consultation, so most GPs charge a private fee for the appointment and the letter. Ask the cost when you book. It is a small expense relative to the treatment, and for surgical cases it is worth doing properly.
