> Each time I had a tooth "cured" (i.e. drilled), this "cure" weakened the structure of the tooth so much that it broke with a period of 6 to 24 months. And once the inside was removed with drilling and the outside has broken, what's left? Nothing: goodbye tooth, hello hole.
I went to a few different dentists a few years ago, and they all said I needed a crown. This was not in my budget, so I went to my grandparent's long-term dentist, who they'd been going to since the 1960's. He was 80+ years old, and was happy to use his tools to sand down my old prosthetic tooth.
He was a cheery old fellow, who still practiced dentistry to take care of his long-term patients who didn't want to go anywhere else. And he gave me the best advice for picking a dentist that I've ever heard:
1. Make sure your dentist's drill is water-cooled - that it sprays water on the tooth that's being drilled. Tooth nerves that get heated die, and then you need more dental work...
2. Never go to a dentist who hasn't been out of school at least 10 years, because young dentists tend to have loans to pay off, and they have an incentive to sell you dental work that you might not really need.
My brother told me about how he got hit with a dental up-sell once. His new dentist told him that he had "micro-cavities" that needed to be filled. My brother was like, "huh? They don't bother me..." But he went along with what the professional recommended. Did he really need that extra work? He doesn't know... But now he has micro-fillings that will probably fall out some day.
I broke my tooth at the lake when I was 12, and have had a prosthetic tooth ever since. I broke the prosthetic tooth off one evening, had it glued back on by a dentist. With the layer of glue, it was just slightly too long, and it started to hit on my other teeth.
The nerves in your teeth shrink as you age. The difference between the nerve size of my root canal'd tooth and its neighbor is incredible. (Did I really need that root canal? My parents could afford it, it was what the professionals recommended, so it's what I got. A friend of mine had a very similar break in the same tooth, but her parents couldn't afford a root canal, she never got it, and still has a nerve on her capped' tooth.)
