Some of the responses here are so insane. You can totally travel whenever you want. I did it before dental school, I’m currently doing it during dental school, and I’ll probably do it after dental school. My taste in traveling is very simple but I’ve gone abroad too (lame).
You won’t forget dentistry, you can do it on a budget, nothing bad will happen financially or otherwise. I’m a big fan of not waiting to do something in life because tomorrow isn’t guaranteed. Dental students are pretty sheltered so naturally they will disagree.
Every day you’re closer to death. You can either wake up every day and try to fill it with amazing experiences or take the dental approach and sit around waiting to get a degree, get out of debt, get married, save for retirement, buy a practice, buy a house, get a dog, the list goes on. Then bam you’re dead.
