Hey there,
If you have AA24, TS24, PAT24, then you don't really have to worry about your personal statement, but if you have DAT scores like mine, then you might want to take time and work on your personal statement.
If I were you, I would either rewrite or change many things from your personal statement. Whenever I help my friends writing their personal statement for dental schools, most of them write it as a college application essay. That's a no go.
In your essay, you should include "commitment to service, why dentistry, how you were interested in dentistry and why you are an unique applicant(you can include dental volunteerings you have done, etc)."
Hope this helped,
Good luck.
