That's a large enough number that you might want to consider medical tourism. Mexico is a very common option. Back of the envelope math: allegedly the bridge will cost $500 or less in Mexico and flights to CDMX + 1-2 night stay is about $300-400 depending on where you live. I'm assuming US due to using $$$$. If this math can be trusted you could budget around $1000 for it.

Disclaimer: I have not done this personally and recommend doing due diligence (lots of research). I do know people that have gone to CDMX for dental care and are happy with the results. Also this requires a passport. If you don't have one that will add around $200 to the cost and 1-4 weeks delay for a rush order. You might be able to get a passport faster (as in within a week) if you were to visit a regional passport center and/or use a private expeditor (though you'd also need to do due diligence on the latter and add $200 to the cost. The only reputable one I'm aware of is Allstate). It also depends on your risk tolerance if you're traveling alone. Core CDMX neighborhoods are pretty safe, esp. when it's light out, but that's another thing to plan around.

Anyways I'm hoping this is helpful info rather than stressful. It's terrible that teeth are treated as luxury bones and not subsidized medical necessities.
