Out in private practice, the AACD is more than happy to let non member dentists attend their courses/meetings for a fee (and a fee that isn't too much more than what AACD member dentists pay to attend the same course/meeting) if you want to (heck right now I'm getting either an actual post card mailing or an e-mail letting me know that their annual meeting is in Boston in a few weeks and the course offerings there, and i'm not an AACD member.
Check out a few of their courses before joining. If they interest you, and you want to, join. There's usually a bunch of good little tidbits that you can pick up and integrate into your day to day practice, even if your practice doesn't spend the majority of it's time doing 10+ unit anterior esthetic cases (which is probably 99%+ of all practices in the US). If it doesn't interest you at that time, then you can always join at a later date if you feel it interests you then
