Preventive dentistry, the kind where the dentist fills cavities as they appear and keep the tooth intact is the most neglected type of healthcare in the US. A poor person can get treated for just about any kind of injury or sickness and pay little or nothing, but teeth aren't included in this kind of thing. Regardless of race or skin color, rotted black teeth put a stigma on a person that can't be overcome by any amount of natural ability or education.
...snip... I calculate in the the past ten years, my teeth have cost me about $6000 dollars. For that price, I still have all my teeth, or at least parts of most of them. My December root canal and accompanying gold crown was $1750. I was given the choice of the rebuild or an extraction.
Just for the sake of whatever-the-fuck, I'll relate my own experiences: When my teeth started to get holes in them, I applied for MediCal (in CA) and got full coverage for low-end amalgam fillings. Then I went in search of dentists who took medi-cal, and the first dentist I found turned out to be a scam artist. I knew I had 2 or 3 cavities, but she pretended to take X-rays, and proceeded to tell me I had 13 cavities, which she was prepared to drill-and-fill immediately. I got out of her chair without a word and left, with her following me out to the parking lot bleating "sir? Sir? Is something wrong?"
I found another dentist, an honest one, and got the 3 (as it turned out) fillings I needed.
When my lower front teeth finally gave out, having been a crooked mess all my life, I went to a nonprofit faith-based clinic that used a combination of dentistry-school students and actual dentists doing charity work once a week. I was able to have all 4 teeth pulled, a root canal and a post, and a bridge across the bottom of my mouth, all for $1100.
So it
is possible for the poor to get dentistry done, but only in certain parts of the country. And I freely admit that even though it was an incredible bargain (and a professional job), coming up with $1100 all at once is beyond the reach of most poor people. I was lucky, I borrowed from family. Took about 6 months to pay it back.
But now my teeth are sparkling with the Incredible Whiteness of Being.
