Dental tourism
Barcelona receives patients combining treatment and travel: competitive prices and easy logistics. Dental tourism works by rules — the first being not to fly to save on the delicate stuff.
The real arithmetic
Implants and orthodontics can justify the flight even paying airfare and hotel; small repairs never do. Calculate the total with stay, not the clinic price alone.
The treatment calendar
An implant has phases with healing months between: you plan two trips or delegate follow-up to your home dentist. The serious clinic explains before charging; the other, after.
Guarantees at distance
Ask about the warranty and what happens if it fails after you've flown home: the clinic with an international protocol has it written. Distance medicine needs a contingency plan, not optimism.
