Dental care is very good in Thailand and comparing it to my experience in the USA way way less expensive!
When I was working in the middle east many of my co-workers would go to Thailand for dental care. Thailand has very good medical and dental care but way less expensive with equal quality than the USA. I would also add in my own experience better service!
Just trying to get into a dentist office in the US is a long wait then the wait in the waiting room. In Thailand, usual the appointment time is the time you actual see the doctor. My own experience was having 3 teeth removed and a bridge made. Excellent quality and care and the price total was less $100. That was in Phuket Town.
Many many web site you can search for a dentist. My own dentist is in Phuket at Dental and Gums Clinic at 143 Phang-nga Rd Taladyai Muang Phuket Thailand Ph +66 076217710 and email firstname.lastname@example.org I found them when I went to Phuket International Hospital as they referred me. The hospital did do dental x-rays and when it came to pay for the x-rays less than $10 wow!
