My biggest concern wouldn't be about how my new teeth work great and look great for half the price.... my biggest concern would be can I get back into the States.... and I'm of Irish, French, and Cherokee blood.... lol.....
A lot of people in Arizona go to Mexico for all kinds of things. Snowbirds [people from Wisc., Ill,. and Minn... etc] go to Mexico all the time for knees, hips, teeth, and medications..... It's ridiculous how much time and effort they save going to Mexico. I don't know how the insurance part of it goes... but if they can afford two homes... one for summer and one for winter... then I guess they can afford dentures without an insurance kick in.
On the other hand... the Canadians migrating to Arizona for the winter... they're selling out and staying away.... because entering the border they have to buy American Health and Auto Insurance.... or at least I think that's what my neighbor said. Hey... maybe Canada will build the Southern Border.... with all the fees they pay to have a place to "winter".
