Glendale, AZ is not far from you. I had a complete teeth cleaning there for $48 (I paid $50 per quadrant in MX) and it was the most extensive cleaning I have ever had. The job is performed by a team of 3rd year dental students at the Midwestern University supervised by one of the staff dentists. Exceptional service and at a lower cost than anywhere I have found. We used to go to Los Algodonnes, MX but not since discovering the MWU. Plus is they will process your insurance claim but I think only for Delta Dental and BCBS. The link below will take you to their clinic page (they have several) where you can follow it to the Dental Institute page for additional details.
Later,
