I can also report I got a great cleaning at Bangkok Smile in Asok earlier this month. Two things I particularly liked 1) on the telephone to make the appointment they quoted me 1,200-1,500 thb, dependent on how much work the hygienist decided she needed to do once she looked at my gnashers. Having accepted the quote I fully expected that once I turned up they’d charge me the full 1,500 - but no, when the hygienist/dentist took a look in person, she told me 1,300, which we settled on, before she started the cleaning. 2) I specified I only wanted a clean and not a dental check-up - but when the work was finished the hygienist/dentist said she’d checked my teeth at the same time and no cavities/no work to be done. I can only assume that if in fact I did have a problem needing dental work, she would have told me. So in effect - a free check-up thrown in with the high quality clean. I will definitely be going back.
