Hello, if you are concerned about whether a dentist in Mexico would be regulated you can go for a trusted dental tourism company like PlacidWay, which is based in Colorado, and ask for a list of reputable clinics and dentist in Mexico. I used them when I had full mouth dental treatment last year. The work done: Under $2500 for same work that the dentist at home quoted $8,000. These agencies will organise your flights, accommodation and even your appointments which is really stress free. If you want to contact them you can send them an email at: info@placidway. com or just visit their site. Good luck with your treatment!
