We also will say that the above post by OLDGUY is totally wrong.
People wouldn't keep going back year after year if they had bad experiences. Everyone we've talked to had good experiences, including us. The dental offices are cleaner than some in the U.S. The dentists and office personnel are very friendly and caring. They speak English and the prices are great.
Popular areas are Progresso at Texas and Algodones by Yuma, AZ. Thousands walk across the border constantly for their dental work. Afterwards they enjoy a good meal and a huge margarita! If you're RVing there are parks close by.
We would totally recommend them.
NOTE TO CUMMINS12v98. We retired to full-timing at age 52 in 1992 without any debt and could totally afford the U.S. dentists. But why pay that much when you don't have to? But then, that's probably why we had no debt....and still don't. :)
