I’ve had horrible dentistry work done in the past and now I’m having problems with my teeth.?

I used to have a beautiful smile. As an adult my teeth have gone to crap. The dentist told me I had a gum disease similar to Gingivitis. He said my gums are eating away at my teeth. I’ve been told by dentists in the past that my teth are perfect but this disease will eventually cause them all to deterioate. They won’t even clean them without my paying thousands because they said it’s a special type of cleaning. So I brush them constantly, for years now. I don’t understand why if I take such good care of them, they look like this. The last dentist said not to brush them often, it will make it worse. But I’m not an ugly girl and I like to look nice but I can’t smile anymore. Now I have black around some of them and the back ones have almost all fell out. A few years back, I had some emergency work done on my teeth. They put these rods into my gums and repaired the tooth around it. I actually had a couple done that way. Now the teeth have fallen out and I have these uglyand shrp rods sticking out. Now with the economy the way it is I have no work and no dental. The last part of a tooth fell out the other day and now this one rod is sharp and hurting me. The other one I had years ago I filed down. I was wondering if I could cut it out somehow. I feel like a monster anymore with my teeth. I spent thousands before and now they are all falling out. Anyway now that the back teeth are pretty much gone, all my food is chewed with my front or that nasty little rod. Please help, what can I do? If I try to cut the rod, will it kill me? I vaguely remember the doctor telling me it was close to the root and to be careful. But these rods are cutting my tongue. I need some relief till I can afford a dentist. Any advise would be appreciative, thanks in advance, Liz
