Depo-Provera Contraceptive and periods

I was on the Depo Provera birth control shot for roughly 6 years. It did stop my periods but that was the only good thing about this shot! I am now 30 years old and it has been about 2 years since I stopped receiving the injection. My teeth are decaying so rapidly that they chip and break as if they are made of layers (like a flaky biscuit). When I first started the injections my smile was pretty perfect. My diet and daily regimens have not changed so I can only attribute the dental issues to this birth control shot.
I also suffered from lowered sexual drive, depression, mood swings/anxiety and insomnia while on the treatment. After several years of my issues getting worse I linked them to the shot and no longer received the injections. Since then my other symptoms have gone away but the tooth decay still lingers.
Is there anyone else out there with these same issues? I desperately would love to find help or others like myself.

I have been on Depo for about 7 years. I never had a problem, I never had any periods at all. When i went off I became pregnant in 3 months. I have decided that I will never go back on it just because everyone has warned me about the horrible bone decay. I am awaiting a bone density test in March and I am very nervous. It took this long to actually start listening to what people were telling me about this drug.especially my doctor. I tried the pill 2 months ago (tri-cyclon_ for the 1st time and it is the worst thing I have ever done. I am depressed beyond words. I have no desire for sex no desire to eat, or to be social. this is where brown stuff hits the fan. I am done with needles,pills and any other thing that put chemicals in the body. Condoms, I have no choice. I am sick sick of being mentally and physically sick, on account of putting crap in my body.
