I Used Listerine This Morning And I Felt A Bit

I used listerine this morning and I felt a bit of pain in my tooth on the lower left hand side on my mouth (I have had either a filling or root canal there before). Now I am in excuricating pain. My jaw is killing and I have pain in my ear. It hurts to drink or eat and hurts to touch the top of my jaw just below my ear.
