Its far more important to be personable and kind as a dentist, rather than a whiz who can make a 25AA but is introverted and antisocial. You get the picture.
You have an outstanding DAT score, but a mediocre GPA. Some people would be discouraged if they had your GPA, and would consider going into a Master's program, but I think if you have shadowing experience and if you know you want to be a dentist, and for the right reasons, you very well could shine in interviews and definitely get into a school. Probably not the top tier schools, but then again, this is dental school we are talking about. Doesn't matter if you went to Harvard or Meharry in my book, you're still a DDS/DMD(mostly). The same is not true for medical schools, however.
