slave4MD - are you pre-dent? Because that MD in your name makes me think "pre-med." When did the University of Rochester have a dental school? It's not one of the schools that closed in the last 15 years or so. Besides, they still offer post-graduate dental education (and have some of the best programs in the country there for stuff like ortho, prostho, etc). The dental schools that closed were all PRIVATE dental schools that couldn't afford to keep their doors open due to the very expensive cost of dental education.
UBTom is right - $30,000 is how much a resident makes in some parts of this country. A resident in NYC makes close to $50,000. No dentist in private practice makes $30,000 a year, unless they work maybe 1 day a week and choose to do so. Even starting salaries in the army and other government agencies is higher than that number.
shark007 - most jobs probably are from replacing retiring dentists. But that's not such a bad situation right now, b/c there are more retiring than graduating. There are dentists out there having a hard time selling their practices b/c graduates have more options and therefore don't have to buy the first practice they see.
The caries vaccine is possible, but not mainstream-reality. Last year our professor commented on why the caries vaccine will always have such a low priority and may never be accepted. If you administer the caries vaccine or any vaccine for that matter - Mumps, Chicken pox, Rubella, whatever - there is always the possibility that the patient's body will have issues with the vaccine and the patient may die. Happens to very few, but is still a reality. However, we still give vaccinces for mumps because the chance you will die from the vaccine is much less than the chance you will die from actually getting mumps.
The difference with caries is CARIES DOESN'T KILL ANYONE. Having a cavity does not result in death - find a report to prove otherwise. So we cannot ethically justify giving a caries vaccine that may potentially kill the patient, whereas having the actual disease wouldn't kill them. Unless they can make the vaccine 100% risk-free, I really don't see major public health efforts to incorporating this vaccine into everyone's lives.
Cheer up shark, none of my professors have yet to tell us "Run the other way! Abandon dentistry as fast as you can! It's not worth it!" Instead, they only have positive things to say about the profession and its future. The Army and Navy scholarships are probably not a bad idea if you are going to attend a private school, but I would talk to people out there who are serving the payback terms of the scholarships before signing up.
