There is One and only one dentist I use in BKK and thats because I can get IV sedation, Ive had this for over 30 years in the UK and here. I have found no other place that does it . Some people write bad things about this practice, and they certainly arent cheap but I dont care as long as I get IV sedation . It costs about 5000 baht the person who does it teaches it at a dental school, she speaks english is I guess around 45-50 yrs old. After youve had IV sedation you will never use anything else. Asavanant is the name , look it up. Youy will have to have a blood test at the hospital and general check up before you do it and they also check a few other things, none of which I had to do in the UK which I find funny as everytime i have it they request this. I do realise you say non sdedation butn ive never found anything that helps
