Well, there's door number two. You observed a "transformation" as a dentist gave her patient a better smile. You saw how "meaningful" an experience it was when she can smile for the
first time in her life! Like...for the first time in her life!!! EVER!!!
That's the problem with finding example personal statements. You copy other peoples' ideas. There are only really two personal statements in dentistry. Bad experiences, and giving the world a smile.
Let me ask you this. Do you know why you want to go into dentistry? If you do, then you don't need to read other peoples' personal statements. The biggest reason why people want to read other people's personal statements is because they want to find a good one and copy it. Take their theme, their development, and what have you. The reason why my own personal statement isn't on DMDstudents is because I know many, many people will take things from it.
