While on a family trip to Bangalore, India me and my wife decided to visit a dentist referred by a family friend of ours. At the outset we were very much surprised to find out that the Dentist had an advanced degree from University of California, Los Angeles (she is still a member of American Dental Association) and had moved back to India after practicing for 7 years in the bay area. I had to take care of crown lengthening, which would have cost me $700 out of pocket as quoted by my dentist in New York City, while my wife needed dental bridges with crowns (cost would have been more than $3000 in US).
After initial consultation we decided to go ahead and get the procedures done during our stay in Bangalore. The dentist and her staff were very professional and they had all the latest equipments in the facility.
The total cost for taking care of our procedures here was $500 hence saving almost 85% for the same quality service.
Now this is precisely the reason why so many people are willing to travel abroad to take care of non-urgent medical needs without any barriers like insurance coverage, cost etc. It also gives an opportunity to visit and learn about a new place which otherwise would not have been possible.
