How can I obtain a Dental Treatment Visa (DTV) for Invisalign in Bangkok, and what consulate should I apply at?

Hey everyone,

for those who were successful in getting a DTV for dental treatment, at which consulate did you apply and with which clinic?

I would like to get Invisalign done in Bangkok and I read that some people have gotten a DTV for it at certain consulates, but that at other consulates people have been rejected saying dental treatments don't count as medical treatment.

My alternative would be to just enter on a tourist visa or visa exempt, though I have been in Thailand ~4-5 months (on tourist visas and visa exempt stamps) every calendar year from 2021 to 2023 and I am worried about being denied entry the next time I fly to Bangkok (haven't been in Thailand for ~1.5 years now).
