Should I try to get into dental school or just become a PA?

I am interested in becoming an DDS but I declared a BS in Physician istant. The problem is that I decided that if I wanted to do pre med I want to major in Chemistry because im strong at chemistry and the cles are much more different. But Im not sure that I could becoming a PA later if I don't get into dental school school. I just want to try to get into dental school because Im a really good student and I shouldn't waste my good academic abilities. Could I still apply to PA graduate schools without a BS in PA? Please give me suggestions. I know that PAs make 80-100k a year but I think that I should try to do something greater. Thanks!
