Grad student missing first year prereqs

[CANgnome]

So i find out that i am missing the intensive writing (one year) and physics (one year) from my undergraduate. Although I do have a semester of physics, i got a D in it O_O.

Would this affect my application if i am deciding to apply to dental school during the summer and finish these courses in addition to my graduate requirements during the subsequent fall/spring?

Thanks for any input.
