hello I have had many problems with my teeth, this sounds bizzare, i get a tingling almost like tiny electrical pulses in my right top lip, i went to the dentist, he filled my tooth I think a pre-molar its fair to say, my tooth is three quarters filled, i have now been back four times, with pain that contiues after this tingling pulsing, my dentist has x-rayed but no evidence of infection, the pain is there and very real, this is really getting me down, my dentist is refusing to remove the tooth, saying it is not infected, sometimes the pain will go away for a few days, but always returns, it is very sore at the top of the tooth, I do have receeding gums also, and a partial denture, i am getting to the point of dispair, living on pain killers, and taking three weeks of doxyxcycline to rule out a sinus ifection, my upper lip stings most of the time, the pain subsides when I go to bed, which is odd, please help

Hello thanks for consulting at Chat Doctor. Firstly tingling sensation could be calculations,which occurs as a result of irritability of the nerve fibers. There are a lot of causes for twitching/tingling, the most common are due to magnesium deficiency. It usually results in hyperexcitablity, muscle weakness, and calculations. So don't worry, try reducing the anxiety by keeping yourself calm, do breathing exercises, try yoga... Since dentist has taken x-rays, and confirmed there is no infection in the tooth. It also subsides when you go to bed, that is the reason,it might be stress related. To overcome magnesium deficiency you could take nutritious food, leafy vegetables, nuts and wheat bran.
