All of a sudden my molar tooth which was already filled started to ache so badly. My dentist was told me it requires root canal almost a year ago but it was fine untile four days ago after I tried to floss and pressurized air between teeth. Then all of a sudden severe pain started. My b12 deficiency symptoms are getting improved and I was happy of getting rid of it but now hypersensitivity of my molar tooth started. I can't eat or sleep no painkillers work and it's steady pain cause my b12 deficiency symptoms to return to somehow. I tried lots of things like enamel repair toothpaste, hypersensitivity toothpaste. I tried Salt water gargle, baking soda wash, turmeric , Tylenol powder wash but non of them worked. I'm going to see dentist today, but this pain doesn't go away. I think dentin is exposed in somewhere probably gum line broken and dentin under gum is sensitized or filling chipped. The best way is root canal but it's not affordable for me at this time. Other option is sealant and also using numbness get temporarily until sensitivity get fixed until dentin covered by enamel fixing paste. My question is is that related to B12 deficiency as nerves hyperactive in order to get repaired. Currently I have severe tinnitus along with double vision blurry eyesight and muscle weakness, numbness in hands back and neck and pain in muscles but lots of these symptoms improved except double vision which is related to lack of eye muscles coordination due to muscle power change on both eyes and brain can't coincide two images, but this symptom also getting improved. I gave no idea why I have too much pain in my tooth but I think it's related to B12 deficiency since that of much of pain can't take that long without abscess or swelling. It's throbbing pain. Hypersensitivity to pressure on tooth that's why I can't eat anything.
Please share your experience and help to find a way to get rid of it.
