Answer:
One office in nuevo progresso, who has a dentist who is an ADA (American dental association) member and is licenced in California charges 400 per tooth, and they are name brand lumineers... and most have pictures of the offices on their websites... they are just like dental offices i have been to here in the us.
the quality of the dentists in Mexico is very high, you just have to research them first..... don't be afraid to call the offices....
I have lived in Texas my whole life and am not scared of a Mexican dentist, many of them are licensed in Texas and California, however there are some that are not as high quality... be diligent and you can get a great smile for less
