I went to this dentist in Bangkok however it was only for Laser Teeth Whitening and I wouldn't use this as a basis for evaluating how they would do on teeth extraction.

The clinic did a reasonable job for much less than I would have spent in the US (their prices are available on the website). If there was anything I was disappointed with, it would be instructions and treatment for postprocedure pain. When the time comes for a second treatment, I won't have any problem going back to them.

I think for more serious procedures like extractions, I would want a larger institution that would be ready for complications that might, but probably wouldn't, happen post surgery. I would go with Bumrungrad. They are respected and have a large staff support you.
