Your son might consider a trip to Los Algodones, Mexico right next door to Yuma, AZ. It’s the heart of dental tourism. There, he can get his teeth pulled and same day dentures for about 10-15% what he was quoted in the U.S. My US dentist quoted ~$14,000 to do that - I went to Sani Dental in Mexico and paid $1,800 and another $2,000 for lodging/meals for a 10-day stay for follow ups and to recuperate. The dentist even kicked in the cost of 3 nights lodging at the Hacienda Hotel (which he also owns). Not the most pleasant vacation, but I got what I needed and didn’t have to mortgage my house to do it.
THAT sir, is very helpful . . . . thanx.
