Competition depends on the overall class, but overall not that bad compared to the Columbia/Harvard type. Classes are pretty easy, pre-clinical courses seem to be graded more stringently compared to other dental schools, and is also not pass fail so there is incentive to try harder. Faculty is hit or miss - most are average, some are definite favorites and will go above and behind, only like 3-4 faculty (mostly in clinic) are genuinely unhelpful and should be avoided.
All in all its a dental school on par with the rest of the country - not the worst and probably upper average, I would recommend it to a friend.
