The people that dropped out realized dentistry wasn't for them. It was like 3 people, and this happens at every school. If you drop out early enough, you're not paying the entire 100k. Nobody has dropped out of my class. Also, last time I checked, 40k is still a lot of money. I'll take that as a consolation prize any day of the week.
Refer to what
@PSUDent18 said. ~20 people in my class are on HPSP, there are people who are graduate assistants in the dorms and therefore are not paying for COL, there are people whose parents/family members are helping them, and then there are scholarships. People figure out ways to lower the cost, so this idea that everyone is paying 470k is absurd.
Of course dental schools are businesses and money does not come thin air, but a lot of the money they use towards scholarships and facility upgrades comes from donors. For the new facilities, someone donated like 15 million dollars. Everyone's tuition money at all dental schools gets used mainly to pay for the faculty/staff that work at the dental school.
At the end of the day, you have to figure out what's best for you. There are tons of posts on these forums along the lines of "help I want to specialize in "X" but my rank isn't high enough. What do I do?". That's why I'm saying if you are set on a speciality like Ortho, OMFS, or Peds, the risk of being in debt is worth the reward because you will be able to pay the debt back with your salary. It's easy for a lot of people who are already specialists to say that all it takes is a little hard work, and to downplay what they had to do to get there. There are so many variables in dental school you cannot control, and it's not always about just working hard.
How did we know we wanted to go into dentistry without picking up a hand piece and drilling a tooth? I hate this argument, and it's such a bad one. You don't have to physically do something to know if it peaks your interest and is something that you find extremely interesting. I can guarentee you that if money was the motivator for everyone who wanted to specialize during their D1 year, they would never make it through residency. Why would you put yourself through 2-6 more years of misery in residency when you could do just as well or even better as a GD?
You're joking right? It's just the opposite on these forums. There are so many people on here that say specializing is easy and only takes a little bit of work. Read through this thread and you'll see that. I really don't like seeing that message when I have plenty of friends struggling in STATE SCHOOLS and everyone acts like it's a walk in the park. The people saying you can easy specialize from a state school either a) are specialists themselves or b) are pre-dents that haven't started dental school so they don't know what it's like yet. There are so many people that didn't have what it takes for whatever reason, and it's unfortunate because saying you want to go to an ivy league school in order to increase your chances of specializing is like saying you're a Trump supporter in real life. It shouldn't be that way.
Again, I know my opinion is unpopular because it's not the "happy-go-lucky" message that everyone wants to read. But I also think it's important to see both sides, and know very well that it's going to take more than a little work to succeed in dental school.
