Anti-anxiety meds help tooth pain from malocclusion?
My wife has been sufering from some pretty bad tooth pain for the past few months. She has a bad bite, or malocclusion, and has had 6 bite adjustments from a prothodontist in the past month. However, this isn't working so far, and the pain only has gotten worse. The prothodontist wants to fix the bite first before looking into any crown or RCT to treat the tooth pain (all in back molars).
My wife is not doing well emotionally, she is very angry about the pain (blames dentists for causing it), and spends 99% of the day focusing on her teeth pain and bad bite.
Five days ago she got a prescription for the anti-anxiety med lorazepam and she's been taking a moderate dose of 1mg per day. This helps immensely with her depression and anger and surprisingly(?) it also helps a lot with the tooth pain, to the point where she says they pain is almost gone.
My question is, is it normal for this type of med to act as a painkiller, or is it possibly a sign that her tooth problems are causing so much distress that she is unable tell the pain apart from the distress? Seems to be a weird question, as she obviously knows if she is in pain or not, but any answers would be appreciated.
Re. the pain: it hurts her a lot to chew food or drink cold liquids. Even when she's not eating or drinking, she has a burning pain in a couple of teeth, and a lot of "pressue" in another tooth, as a result of her bite being off. She thinks her bite problems are caused by a filling she got 6 months ago, but I think it could also be related to her night time teeth grinding.
We live in Canada, and maybe one option is to see an oral surgeon, although we would to have the dentist refer us. Is there any value in seeing the oral surgeon to perhaps look into the pain issues? I don't think the prothodontist really seems to know what is causing the pain.
