Nothing is black and white when it comes to education. I would still try to get into your old dental school. Worst case: can you get a job with as a dental assistant (where you don’t need a licence unless you already have one), and build the case either for your old dental school or even a new one.
Like most who know better than me (I’m a lawyer, so my educational experience is not relevant to your situation), you cannot get away from your record.
That being said, educators are aware that bad things happen to good people. Can you speak to your advisor at your former dental school on a video call to explain your situation and your desire? Explore with them EVERY possible avenue that you can try to get back to the school. And if not that school, another school. After 2 years, I cannot believe that there is no caring person at your old school who wouldn’t try to help you out.
If there is a will, there is a way. Never, ever forget that. And never give up if dentistry is what you want to do. Never.
