...is that I can see all the kids I want to and none that I don't.
The upside to being a pediatric dentist would include a potentially higher salary, the prestige of being a specialist, getting to work with kids all day, the challenge of difficult cases, and the satisfaction that comes from knowing you're doing a job that would have most other dentists back in school getting their MBA. It will also be easier to set up an office. You could go pretty much anywhere and be busy from day one. Lastly theirs not a lot of CE on treating kids so if you want to learn more a residency is one of the only ways to do it.
You won't get just the bad apples. There are plenty of people (usually with a higher dental IQ) who are willing to pay more to take their well adjusted kid to the pediatric dentist. But you will get a lot of bad apples.
As a GP I would say about 40% of my patients are under 18 and 20% are under 12, which is fun and we have a good time, but I don't think I could do it all day. To me treating a 3 year old is not an exercise in perfection but just fixing the problem as quickly as possible so you don't use up their attention span and get a fussy kid. Pedos can whip out a pulpotomy and SSC in about 5 minutes which is an excellent service to the patient. I just happen to enjoy being able to take my time, refine my work, and aim for excellence. I also enjoy the variety that comes with root canals, crowns, dentures, perio, etc...
My friends that went into pedo said the first few months of their residency felt more like rodeo school (learning to hog tie kids) than dental school. One pedo assistant I know said it was a daily experience to have yelling, crying, screaming, and puking. GOD BLESS THEM for they are better people than I.
You'll get enough exposure in dental school to know whether it's right for you by the time you have to make that decision. I'd recommend keeping your grades up so if you decide its for you you'll have plenty of options.
JMHO
