Maybe. Post -op it could be almost anything. Just try some of that Sensodyne toothpaste for now,and if it doesnt go away in awhile or gets unbearable,then check it out. Well,thats what I would do.
Wishing you a good post-op recovery!
OOPs -sorry! Just saw that you are already using the special toothpaste. Still,I think thats
about the best thing to do for now anyway. Who wants to go to the dentist post op?
Only thing is to be careful if you have any cavities or infection/inflammation-this can be dangerous if you have an infection in your mouth. I use peroxide as a mouthwash to cleanse my mouth sometimes.
BTW-Did you get a dental check up before OHS? Most people do , just to make sure there is no infection lurking.
