Im in 9th grade and im considering wether or not i should take further steps in pursuing a career as a dentist. How compeptitive is dental school? How difficult is it to start one's own private practice? Also, i have a gap on my bottom row, and a smaller one on my top row, im not sure if i need braces, whenever i ask my dentist he tells me i dont but im almost positive i do. Will my imperfect teeth effect my chances of becoming a dentist?
