Not only are you helping people with their total health, but if you're helping people who are low-income, you're making sure that they're not marked for life as being "low-class"... (society's perception, not mine). Just try getting a decent job if your teeth are a mess. I really think that people shouldn't lose college and career opportunities because their parents didn't care enough or didn't have the education or money to take care of their teeth. Sure people do overcome this all the time, and having bad teeth isn't the absolute worst thing that can happen to a human being.... but it can and does cause poor self-esteem and causes people to view you differently. I want to be a dentist to help people and am pleasantly surprised to see that a number of others give this as their primary reason too. Don't get me wrong, a good income and quality of life are great too, but you really can get those things in other careers where you don't have to get so intimate with people... I hear actuaries have it pretty good🙂
