I have a son with Tourette Syndrome and since infancy, we have always seen a correlation between his teeth and his overall health, but especially related to his Tourette tics.
When he has a tooth coming out or in, his tics skyrocket!
I recently had a thread running on the TS Forum here about my son having tic increase again related to a wisdom tooth

We have heard from others that this is a common reaction in people with TS and I found this chart on an informative holistic dentistry site to be very interesting
