In the last 2 months, I have had 3 root canals, 2 abcess teeth,(the same one abcessed twice, the second time it was extracted) and 3 temporary crowns put on. Now, after all that, I have another molar that has a filling it from a long time ago, starting to act up...shooting pains like the nerve is agitated. What on earth could be causing so many of these issues all in such a short period of time? I brush 3 or more times daily. I'd heard that if my hemoglobin, b12 or iron was low that that may be the cause. I'm tired of being in pain all the time...any ideas would greatly be appreciated!!!
