Algodones claimed to be the moler capital of the world. 300 dentists in one square mile. People fly in for dental work all the time.
It’s about 10 miles west of Yuma Az.
I had all my teeth capped and had 5 root canals done there 3 years ago for a smidge over $10000. Would have cost me $60,000. Plus in the states. And they guarantee the work for 10 years.
