I was just about to mention this. I will say I was informed of many "issues" with the program from my friends that graduated before I got in, but none of it complicated my desire to learn. After wrapping up my third year next week, I honestly love the program I am at right now and wouldn't trade my experiences here for the world despite what I was told. I wouldn't focus on those opinions as a deciding factor because for the most part, your education is what you make it. The people having a difficult time will make it known for the most part and you'll hear a lot of the "bad" going on. It's subjective, maybe some of the people saying the bad things about the program have always gotten what they wanted and have never been told no. I'm only speaking on behalf of my experience in school, not everyone else.
To give some insight about me, my kind of work ethic is more of being a hard worker and "no one will outwork me" type of mentality. I was a 3.0 student in high school and a 3.4 in undergrad. I guess I was a slacker in the classroom growing up, but I've also been independent since I was 17 (I'm 25 now) and didn't have the support at home to even go to college. It wasn't until dental school when I found out I love to learn so I didn't have the "gunner" mindset coming in. Long story short, I am doing the best I have ever done in school and am currently in a position to specialize. I even help other students (those aspiring to specialize or not) as much as I can because I knew what it felt like to struggle, only hoping to make it a better experience for them. Those professors I heard bad things about before starting school ended up being my favorite mentors and have taught me the most. Are there some things I don't like about the school? Sure, but I don't focus on any of that because it is out of my control. I am just grateful to be there after only applying that school and being waitlisted my first cycle. All of this yapping just for me to tell you dental school is going to be "toxic" anywhere. Not just with faculty, but also within your future class. I could probably find a few people in my class right now that don't have anything positive to say about the program we're at which is a shame.
I just read that you withdrew after typing all of that. I wish you the best of luck and hope my response is helpful for when you apply again.
