May I suggest going to a dentist in Mexico? I think the plane + expenses are much cheaper than a US procedure.
That said, there should be an online community for this kind of thing so that you can pick an affordable doctor without risking your health.
Personal experience: My wisdom tooth extraction cost me around 5000 pesos (one side, bottom teeth), which should be 250 dollars at most.
It was done by a maxilofacial surgeon which my dentist recommended; he was good - he used a modern technique which didn't require cutting flesh. In a few days I was able to work from home 🙂
