Whenever I have dental work done, I take a little extra gabapentin beforehand. So far, so good!

Also, we are not supposed to use the regular numbing agent. My dentist knows this and uses an alternative drug. It isn't as long lasting, so I needed multiple doses during a root canal, but it worked just fine.

I would make sure that your dentist is knowledgeable about TN. I switched dentists after diagnosis because my dentist said "he had heard of it!" I trust my current dentist completely.

I hope this helps.
