Hi @lustarr and all.... just a quick note as noticed this just now: I have had TMJ/TMD over the years and then my adult daughter got it. Both had night guards made but I cant wear one... anyway, long story short, both she and I are on/were on Zoloft for over 15 years and I just wanted to cut and paste one article re Zoloft and other antidepressants and TMJ if that is OK. You could do a search too ... this was just the first result I got. She is still on Zoloft and is getting by with night guard. I am now off Zoloft and having lots of jaw and ear pain, tinnitus etc. too long to repeat here; recently at a new dentist, he felt my jaw when mouth open and shut and said: great, jaw is moving nice and smooth? What???? Well then my pain in that area is from something else then..here we go again! J. p.s. Hope this may help someone somewhere if applies.

Paste:
Drug-induced TMD:

In the last few years, research has shown that Selective Serotonin Reuptake Inhibitor (SSRI) medications such as Prozac, Paxil, Zoloft, and Celexa may cause clenching and grinding of the teeth in patients who have never done this before and will increase these behaviors (both frequency and intensity) in those known to clench or grind their teeth.

This side effect is relatively unknown to physicians, although we continue to educate them when we can. If your jaw pain / headache symptoms started a few weeks to a month or two after you started taking one of these medications, we would suggest you alert your physician to this, as the symptoms could well be related to the drugs.
