As KD said: I also feel for you, Lynda.

I've not tried Topamax. The (most recent) medication my neurologist Rx'd is Relpax; at the time she prescribed it (2005), I'd come across one lone site on the Net where someone else's neurologist also Rx'd it for TN. (I wonder if maybe more neurologists might be Rx'ing these days.)

For dentistry, my neurosurgeon suggested seeing a dentist who uses conscious sedation. For any prolonged procedures, he said that it should be done via hospitalization. Uhhh, I'm not to fond of that idea, and I've been procrastinating finding a new dentist.

Have you heard similarly?
