Advice on BCPM courses

Hi! I am a Canadian student and I am planning on applying to dental school. Right now my cGPA is 3.5. I haven't taken my DAT just yet. But, my main problem is regarding the BCPM gpa, because I took the basic physics and math courses over 3 years ago in my freshmen year.

During that time, my family was having a very difficult time because of a massive house fire that I had experienced. This trauma along with the stress translated into very bad grades (2.4 gpa). But I worked really hard to pull that to a 3.5, my last 2 years have been 3.8-4.0. Do you think US dental school admissions will look down at the low BCPM (3.2-3.3) which is being pulled down due to the terrible physics courses? If so, what should I do to improve?

Thank you!
