No need to PM!
Both my teen lads had orthodontic treatment (braces/retainers) conducted at Bumrungrad. We were very happy with the cost, and the outcome compared to what it would have cost in NZ.
Likewise, I had a range of dental work done at Tantakit Dental and was also impressed with the treatment. Other staff at work also used Tantakit, one for a 'root canal'.
Cheers, TK
