Is it possible to do a Master's or Post-Bacc online, and if so, would dental schools accept it?

My undergrad GPA was pretty bad (2.97 overall) and so I'm thinking a post-bacc or Master's will be necessary. Unfortunately, there are no programs close by and I'm not sure if I'll be able to relocate anytime soon. I found this program: Clinical Microbiology | The George Washington University from GWU that appears to be an online Microbiology Masters, and I've found some other possible programs. My DAT score... Is it possible to do a Master's or Post-Bacc online, and if so, would dental schools accept it?
