Bryanna,

Thanks for the response. Yeah, if I had known she was going to use formocresol I would have bolted. My understanding is that they dip cotton in it and wring it out so it's just the vapours and not actually liquid like they still use on kid's teeth (which I can't believe!).

My regular dentist, who is a pretty decent guy, said he took extra care to irrigate the tooth before filing. (he personally does not use formocresol or amalgam and I never considered asking the first emergency dentist since she was quite young and I just assumed)

My question is that at this point if the formocresol or the calcium hydroxide or the gutta percha has injured the nerve would extraction make the situation worse?

I now have burning sensations that move from my cheek to my forehead to my jaw (the entire trigeminal distribution) and this scares the crap out of me. If I never see a dentist again it will be too soon. I just don't want to make things worse.

I go to an endodontist on tuesday. What do you suggest I ask them?

You have seen this before? Have you seen it go away?
