Frankly, there are pros and cons to living by yourself and with a roommate/roomates. Make a list detailing your pros and cons. If you want more friends, sure you can be friends with your roommate, however, roommates arent always friends. in Dental school you'll be taking the same class as all your classmates and at the same time. There'll be tons of opportunity to make friends. Everyone forms groups/clicks and generally stick together. But yeah, I'd recommend posting that you're looking for a roommate on the FB page aswell, and/or go though the school. Ask the school and some match students up. If you open house is at the end of this month you can casually bring it up in conversation that you're looking for a roommate. Ask people what they're doing regarding their living situation. It does work better if you and your roommate get along but also remember that friends dont always make the best roommates. Goodluck.
