Are you still in your dental school in your country? I would strongly suggest you complete your studies there.
To go to dental school in the U.S. you first would need to get a bachelors degree. With your SAT score taken two years ago, the likelihood of you getting full funding to attend undergrad school here is extremely extremely low.
Assuming you somehow completed undergrad, you would then have to apply to and get accepted to dental school here…which very competitive for admissions.
You would need to come up with funding for many years of costs to become an oral surgeon here.
Frankly, I don’t think this is realistic for you now.
Get your degree where you are…and celebrate that you can do so.
