thanks very much, right now I have 6 fillings and 2 of them aren't so big, I also have a stainless steel crown that was supposed to be removed along time ago and I can taste electrical currents comming from that crown. on my upper right tooth I have a root canal that was never finished because the dentist I went to opened up a good tooth and just filled it up with putty and it got infected, I was young so I didn't know any better and she didn't tell my parents about the mistake she had made, over the years this tooth has calcified and has been rotting inside since.
