Medical tourism (dental tourism) is a novel concept and it is not a very new thing
, it was there since ages. Since ancient times India was the country of choice for medical and dental tourism as in olden times only India has Ayurveda and Yoga in India. People from all over the world travel long distances and come here for their treatment, Indians had the first written text book of medicine with them and now in recent times as we have new and faster means to travel across globe and most of the credit goes to newer low cost air travel --- more and more people are going for medical and dental tourism.
Dental tourism is a branch of medical tourism where a patient comes to a country gets his dental treatment done and enjoys culture and scenic views during that time. Usually patients from developed countries like America and Europe travel to Asia for there dental treatment as it perfectly suits their budget. Instead of paying thousands of dollars for their dental treatment in there home country now people have a variety of options that will give them good result and satisfaction at around 60 70 % less cost. It doesnt mean that the treatment here is sub-standard, dental clinics maintain high quality sterilization and have a good dental lab with them and they will give you best price dentistry with your time preferences too
