Dear Alex getting a tooth root canal filled was the start of my illness, of course has I want ill at the time I let my ordinary dentist fill it and found later she had filled it right up to near my sinuses she know the tooth was also badly infected still not knowing the cause of my illness i stupidlylet her remove it too she first broke off the filling, most of which i swallowed, then broke off the tooth, drilled and cut out the roots and just sewed it back up. If only id known then what i do now. Two days later i declined rapidly. i now have to have he site checked next week for infection, bacteria whatever. I dont care about the tooth not being there just wish id have known then what i do now
