I have had work done at the Bangkok Smile Dental Clinic. Originally I made an appointment on line with them. They are very good, even my own dentist here in NZ was impressed with their work. One thing is if you are having a lot of work, you must make time for it. I had 3 appointments when I first arrived in Bangkok, for xrays, moldings, fillings etc. Then 3 weeks later I was back there and had 2 more appointments. The appointments ranged from 1-5 hours. I did have 3 crowns, some veneers, a couple of fillings and a plate refitted. The price all up, dentist, flights, accommodation was still about $500 less than just going to the dentist here. I would highly recommend getting teeth, glasses done in Thailand.
