I was mistaken, just remembered it was about $150 a tooth for the procedure and I have ten of my twelve molars remaining. Two other teeth were broken and I had them pulled years ago.
The $100 per tooth figure was what another Mexican dentist wanted to charge. I did not want to go with the cheapist dentist and hired a more expensive one instead.
My stay in Mexico cost less than 2500 dollars, saved a bunch of money. Rented a cheap hotel room in a working class section of town rather than the expensive beach resort room. My teeth were cleaned for "free" the first day, the drilling and replacement lasted four days. Had to pay in travelers checks after each morning of drilling and replacement.
