Yes!! Of course Creighton is good. They are one of the best schools clinically in the nation. They always rank in top 3 in operative for national boards and consistently rank in the top 10 in overall scores the last 7-9 years. We are probably the only school in the nation to have more patients than we can handle. For that, we have to reject some patients. I know other schools have a hard time finding patients. For example, some of my friends needed extraction requirements. There was a patient coming in with a full mouth extraction and it was done by 3 students because they needed credit. Here, we do so many extractions that by the time you leave, you will be very comfortable. Also, I think we are only(or one of the few schools in the nation) school that let students do implants. As I said before, we don't have any specialties(post doc programs) so if our patients need endo, we do it. Some of my friends have done a total of 2-3 root canals throughout their years in dental school. It's rare to find people who've graduated here have less than 10-15 root canal treatments. As you can see, the things they teach you here will definitely prepare you to work on your own right off the bat after graduation.
Creighton trains general dentists. I'm sure schools like Harvard, UCLA, UCSF and more have a better specialization rate. But if you want to do general dentistry, there is not a better school than Creighton. Good luck!
