I went through years of struggling with my teeth, and now I have dentures. There was crumbling, breaking, pain, and expense. I think a lot of it was from too much sugar or diet soda and not enough brushing/flossing. Accepting that I was going to lose my teeth was difficult.
Its been a couple of years now. But now that I have dentures there is very little stress - no breaking or pain. I was able to get implants on the bottom, which is better than regular dentures. Implants are expensive. Fortunately I had a dentist and surgeon who worked together well, and this was done over a couple of years. Cosmetically, my false teeth are straight, white, and beautiful. There are some foods I will not be able to eat again without cutting them up, but its not a big deal. I don't feel comfortable letting people know that I have dentures, since it seems to be used to make fun of people. But now that I am used to it, I'm happy with what I have, and glad to know I am not going to have to struggle with this any more. Its done.
I do think people should fight to keep their natural teeth, but financially its very difficult to do - especially in the US where insurance policies don't cover nearly enough.
