Why would someone's tooth suddenly develop
a painful sensitivity to cold stuff (even
something as minimal as air blowing across
said tooth during the act of inhaling) out of the
blue? This person was fine, woke up this
morning with no problems, came to work, and
suddenly it was OW OW OW. Also, this person
has a cold and congested sinuses so he has
no choice but to breathe through his mouth.
