question: Hello doctor, I flossed by a tooth where a filling almost came out and my tooth and gum have been hurting all night. Also have a tooth that is by this molar that fell or chipped out. I do not know if it is an abscess or an exposed nerve in my molar that is right behind it. Took Tylenol 2 every 6 hours twice. It did not help. Used Benzocaine on the area. Helped 20 %. Do not feel comfortable using it at home.
