I've only had the one attack of TN (thank goodness) but strangely enough, mine too followed a dental procedure. It mostly attacked my jaw along the lower branch of my trigeminal nerve, and was treated with Tegretol.

Thedspeth and Shelley, I have no idea whether my TN was typical or atypical, but I wanted to let you both know that some-one is thinking of you!

I hope you both get relief soon as I sure do remember how nasty those shooting sharp pains can be.

Sending you both lots of positive healing thoughts and prayers.
