I have been to a couple in Pattaya that barely looked in my mouth. One did not look in my mouth at all for a serious problem where I had pain, just did an x-ray. The other looked for about three seconds and refused to do a cleaning or a crown I needed on a cracked tooth and did not charge for the visit. Don't ask me why. These were places with good online reviews, not just any place I walked into.
I will be seeing the nice place in bangkok again soon. I also had a great local private practice dentist in Chiang Mai that did good work.
Sorry to say again, but I'm biased about the bad luck encounters having something to do with Pattaya 🤷🏻♂️. I consider myself lucky it happened on the first visit before any major work so it did not bother me much, I just never went back.
