Health insurance                                           

Some health insurance companies can refund Hungarian dental costs.
But this amount in Hungary covers an incomperably higher self-payment rate of total cost.
Despite your extra costs ( travel & accomodation ) you still can save up to 60% - this means you can have a FREE extra holiday in Hungary !
