2 weeks ago i had a large cavity filled. A week later I went back to have another tooth filled, while I was there the dentist check out the last tooth she had worked on. I had very little sensitivity in the tooth a first but it went away. As she poked at the tooth I still had no pain. That was on wednesday, then thursday morning I was rear ended. I ended up with severe cervical strain and pinched nerves. I was put on painkilles and muscle relaxers, Monday when I was not taking the meds due to having to drive i noticed that my jaw was hurting. The next day it was worse. Now wednesday it is unbearable and the dentist today said i have acute pulpitis in that tooth that we had all ready fixed. Is is possible that being rear ended caused the pulpitis in the tooth? I know my mouth slammed shut because i was singing to the radio.
