@maxdancona,
I haven't personally gone to a Mexican dentist, but a few years ago, while visiting Mexico, a friend tripped and broke three front teeth. She not only had the root canals done, but they fitted her with the caps and all. I'll say this. I broke a tooth years ago and I've gone to half a dozen dentists since then and my teeth are finally even, the cap was way too big and I had to ask over and over again for it to be fixed...
I wish I could remember the name of the dentist, but we were in Mexico city. A very modern city with great architecture, schools and so on. Perhaps someone can give you a referral, but I don't think you'll be disappointed, I'd trust them before I'd go back to a few of the dentists I've gone to here.
