I'm not a dental student yet, but since everyone is giving you a hard time, I can tell you what i know. Most dental specialties are very competitive. Orthodontics, OMFS, endo, and perio are the toughest. You have to be in the top 10 percent of your class and ace the boards if you want a shot at any of these residencies. Obviously the competition in dental school will be quite tough to make it in the top. So if you wouldn't be happy as a general dentist, then don't go to dental school-- specializing is never a guarantee. Hope this helps.
