Is it tough to find employment in ND? When I was in Fargo many years ago, everywhere you looked places were hiring. Hospitals, restaurants, mechanics, hotels, all manner of industries, EVERYONE was hurting for employees. It's not like that now?
Also, I wouldn't worry about the lack of dental student culture, in my opinion. If anything, as long as you have the drive, GPA, DAT scores, and extracurriculars (which so far, you have shadowing and you drill, which I think are good), you can still have a competitive application.
