Before you book anything
Get a written treatment plan based on your own photos or scans, not a generic price list, and confirm exactly what it includes — consultation, scans, temporary restorations, and follow-up visits — so there are no surprise costs once you arrive.
Medical information to have ready
A list of any medications you take, allergies, and relevant medical conditions should be shared with your dentist before you travel, not on arrival, since some of this can affect treatment planning (for example, certain conditions affect healing time after implant surgery).
Existing dental records, if you have them
Recent X-rays, a panoramic scan, or notes from your regular dentist can speed up planning and sometimes reduce the need to repeat imaging once you arrive, though most clinics will still want their own up-to-date scan for surgical planning.
Practical travel logistics
For implant cases specifically, confirm both visit dates in advance, including the gap between them, and plan flights with some buffer around your appointments rather than booking a return flight for the same evening as a procedure.
Questions to have answered before you fly
Total number of visits required, what each one involves, the written warranty terms, and a direct contact for your coordinator — all of this should be settled before you book flights, not figured out once you land.
What to actually pack
Any medication list or existing records mentioned above, comfortable clothing for potentially longer clinic days, and — for procedures involving sedation — arranging for someone to accompany you or help you get back to where you're staying afterward.
