I can't diagnose or prescribe as a lay person but I would suggest googling the side effects of the drugs in question and see. I often have odd pains in my mouth area, jaw line, bones of face. Sometimes its sinus issues or eustachian tubes or the glands in our upper neck that feel like the ears/jaw. You may have been grinding your jaw in your sleep for example. My understanding of mouth pain is that teeth pain can refer to other areas nearby. My dentist was able to help my husband when he had jaw pain. So it could be helpful to have your dentist look at your mouth, although I know you said jaw. Good such, wishing you find the answer.

Are you clenching your jaw?..... It could be going on during your sleep..... I grind my teeth in my sleep and sometimes have jaw pain

You can get a mouth guard to help with grinding and that may be due to anxiety from going off the meds...… You can buy one over the counter I believe in a drug store or a dentist can make one custom for you.... xo

Tooth discomfort (pain) is a noted symptom of Citalopram (Celexa) withdrawal. As with all the other withdrawal symptoms it will stop as the chemicals leave your body, are completely flushed from your renal system and your body readjusts.

I wear a bite splint at night. I asked the nurse at my psychiatrist’s office. She said that he said no. But I find it very interesting that it just started now.

I looked it up in 2 different Medical/Psych Drug References and got that info....just an FYI.
