I imagine the biggest issue for most folks regarding state vs private is cost (although the cost of some state schools is nearing that of some privates). My advice on this is to think of dental school as not being "all about you." Sure it would be nice if your folks have lots of money and can afford to foot your costs. But if not, then tell yourself that you might at least be able to provide such a benefit to someone close to you from the next generation (your kid, nephew/niece etc). There are ways to mitigate the cost differences (military and public health service etc). Such duty may not be your preference, but again, it might help if you think in terms of future benefits that you can acccrue for your family.
