IBGM or Dentistry

So, I’m wondering what major I should choose for HKU. I am fully aware both are very competitive, but I just want to give it a shot. So, I don’t know if I should apply to HKU IBGM or Dentistry. I received a 41,  but all my chem, bio, and math aa was a 6, while my economics SL was a 7. So, I’m not sure which major to write my statement according to and choose as my first choice.
