Washington Dental Clinic, Tijuana. I went there and they were great. I got a root canal for $250. Actually $245 because they reimbursed me for the parking fee on the American side. And this is how I know they are credible and honest: I insisted on an additional tooth being pulled in addition to the root canal. They said: "But there's nothing wrong with that tooth. We recommend you don't do anything to it". If they were greedy, they would not have ever said anything like that. Then after they pulled it, they told me "We examined the tooth we pulled and you were right. There's a microscopic infection. No one would have caught that for a few years probably. It's good you knew something was wrong". And that tooth cost $45 to pull 'cuz it was a molar. Smaller teeth are cheaper. I love this dental clinic. http://www.washingtondentalclinic.net/fees.html
