is it possible to get an infection after a routine cleaning? i was perfectly fine before my last cleaning, the DAY AFTER, my teeth hurt, which i thought, well, that can happen after a cleaning....but it got worse and felt like cavities, went back a month later and nothing found. two weeks later a huge sore appeared on the roof of my mouth, my ear hurt, jaw and upper neck was swollen, but the pain in my teeth went completely away after that sore appeared. over the next month, sore went away, jaw went down, but had allover hot feeling and muscle pain, this went away after 2 weeks and then the jaw swelled up again! seems to get better, then worse, etc. dr thinks some kind of virus....i think it was caused by the cleaning, as i didn't have anything until after that....could that have been it,? thanks!
