That date is correct, November 29, 1995. Here is an AP article with the story of the game and the fight-

However, one correction- it was not Aaron Zobrist that lost a tooth. Zobrist was not involved at all in the fight, but he did suffer a severe ankle sprain late in that game, and missed several games after that (I think he missed 4 games).
It was Deon Jackson who lost a tooth, and had another one chipped and a couple others loosened when he was elbowed hard in the mouth by Villanova player Chuck Kornegay on a rebound. That is what started the fight, which lead to the ejections of Bradley's Ben Coupet and Villanova's Jason Lawson and Chuck Kornegay. Deon Jackson was taken to a local hospital and had Xrays which showed no fractures. However, he spent many hours in a dentist's chair upon returning to Peoria for some reconstructive and cosmetic dentistry work.
