I started having really bad tooth pain, like all of my teeth on the upper jaw. I have been clenching my teeth, which I never did before. I thought I was gtting TMJ or something, and kind of stumbled upon Singulair as the cause. I have been on it for a month. Now that I have read the side effects, I have also had stomach pain (I thought I ate bad food yesterday) and have been overly tired. If I didn't start looking for a cause for all of this tooth pain, I never would have made the connection! That's scary. Also, Singulair does not list this side effect on their website, it only appears at the various pharmacy websites that sell it. I am going to complain to Singulair about this. I would have suspected it a lot sooner!
