I do, 45 minutes each way via car. Most of it on the highway. It gets tricky a few days of the year due to weather, but overall it's worth it for me. Housing near campus is way too expensive. I know other students (and dental faculty) that commute similar distances.
Oh yes. I didn't mention in the other thread that I'm not alone. Other classmates have significant commutes. Some faculty and even the pre-clinical dean live right by me. The class below me has 6 people at or beyond me. Also, I'm almost all highway and most of it is carpool lane. Have still never had big delays (wrecks, being pulled over, etc). I don't know how it is for you, but unpreidcatble traffic was my concern, not the distance. And gas, I guess.
I had a ten minute walk my first two years at NYU then moved out to Jersey to be with my wife my third year. The commute was an 1.5 hrs one-way and nearly killed me - I had to move back to the city after 8 months.
It's a lot harder to commute in dental school than in undergrad - you'll be spending a bunch of time at school late at night and on weekends. I wouldn't consider it if it's more than 30-45 minutes and DEFINITELY not more than an hour.
