After that's healed, I have to get a replacement tooth mounted on the post and that's another $2000ish. I believe my dental plan will cover $1000 of that.
I don't understand how an implant can cost $4000. It was an hour of time in a dentist office. It seems about an order of magnitude too much. FWIW, I had two estimates and that was the lower one.
Compared to over $400 USD insured in the US.
The cheapest SFO<->TPE flights cost $468.
It might not work out cheaper for you, depending on your insurance plan, but it should be thought of as a serious option for all non-emergency operations.

It took a bit longer for me, a second dentist came to help towards the end.
