Hello, welcome to the forum. I'm sorry this is happening as a person that really detests tooth discomfort. One potential side effect of Ranexa is dry mouth which can lead to an increase in actual teeth issues. Have you been to the dentist lately? That would be my suggestion to do first. Make sure all is well with teeth and gums. Sudden gum recession can cause all over tooth pain. So, just to rule out any dental issues, best to have all evaluated. Then speak to your doctor. It's not in the literature of the drug that this is a reported adverse event which isn't to say it's not one for you. But it is hard to track. Your doctor is going to have to work with you. But they will want you to have had a dental exam first.
