Why does bending, sneezing, stretching cause toothache?

After being unemployed and sedentary for four months, I started a job four days ago that requires quite a bit of physical activity. Yesterday I got a toothache in right upper molar which had root canal done on it a few years ago. Today I am having pain in the tooth when I bend over, stretch, or sneeze. Anybody out there have any idea why this is happening? Thanks!

Why does bending, sneezing, stretching cause toothache?
It sounds like you still have an abscess on that tooth or perhaps in an adjacent tooth. Raising your blood pressure through physical exertion will cause the inflamed area to hurt.





Either that, or you are bumping it hard with the opposing tooth when you do these things. Are you clenching your teeth together whenyou exert yourself? Most people DO bang their teeth together when they sneeze.
Reply:It might be swelling and pinching the nerve from tooth to ear. apply a warm heating pad.do not leave on more than 20 min. at a time.
Reply:You have to have a cavity somewhere on that tooth, otherwise you shouldn't get a toothache. When you sneeze, bend etc, the bloodpressure goes up a bit and your pulse quickens this will resound in the bad tooth. You need to see a dentist.
Reply:go back and see the dentist again
Reply:It might not be the tooth at all.


Do you have a head cold with sinusitis? You mentioned sneezing so i was just wondering.


Sudden movements will cause pain in the maxillary sinus which can seem to be coming from upper back teeth.


If so, treat the cold symptoms and the pain will disappear.
Reply:DR. SAM GIVES A GOOD OPINION, IF I MAY ADD,THAT THE BENDING OVER OR STRETCHING CAN ALSO PUT PRESSURE IN YOUR NASAL SINUSES AND CAUSE YOU TO BELIEVE THE PAIN IS FROM A TOOTH PREVIOUSLY ROOT CANALED. IF YOU BEND OVER WITH YOUR HEAD BY YOUR KNEES AND ALSO FEEL PAIN WHEN BENDING THIS MAY BE A SINUS INFECTION.


HAVE YOUR DENTIST EVALUATE THIS AREA WITH AN X-RAY TO MAKE SURE THERE ISN'T AN INFECTION IN THIS TOOTH OR THE ONE NEXT TO IT.
