Bottom line is, you can't make everyone happy. Some of the negatives have been over stated or over simplified. The Dental Corps is not in any danger of going away at this point. Yes, some of the things on the list are a hassle and some aren't. Some are so minor, I can't believe anyone complains about them, but like I said, not everyone will be happy.
I like being an officer. I don't think it has taken anything away from being a dentist. Matter of fact, it has provided some opportunities that wouldn't be available in the civilian world.
I think the list above is a good one. The only way you will know if it is right for you is to do your own pros and cons list and experience it yourself. I have been in long enough to hear all the horror stories and have found the vast majoiryt of them to be completely false. I have also heard all the glorious stories and have found the vast majoirty of them to be spot on or at least mostly true. Thing is, what I find + or - you may see the other way.
So my advice is this. If someone is telling you all negative stuff, don't listen. They will never be happy anyway and their opinion is probably skewed. If someone is telling you everything is rosy and there are no downsides, dont listen. They are a sunshine pumper not in touch with reality.
I've got almost 13 years in. I can say that I love being in the AF. I'm glad I joined and I enjoy my service. But, I realize there are some things that are a true pain and no one really likes to do, but that's part of life; military or not.
