This doesn't happen to many
people, and as far as I know there's
no actual research on this.
What's probably happing is your
teeth don't actually hurt, but when
your brain receives loud high-
pitched noises that signal gets mixed
with other parts of your brain so it
thinks it feels pain from your teeth
when it doesn't.
Brains are weird like that, as they can
often get signals crossed and make
you feel things that aren't there. For
example some people who have
limbs amputated still feel sensations
like pain from the limb even though
it's not there , the brain is just
making the pain up.
