I need assistance for a really bad toothache. what would make it better?

Root canal: Sounds like a root canal problem. Until you get this done, try taking an anti- inflammatory dose of advil, (ibuprofen) 800 mg every 3-4 hrs. But complete pain reliefs won't happen until the tooth is treated!

Advil and tylenol (acetaminophen): Sounds like an infected tooth. Make sure you see a dentist soon, to get that infection treated. Until you can get it, try alternating 200mg Ibuprofen with 2 extra strength tylenol (acetaminophen) every 3-4 hours.

Go see a dentist: Your problem needs to be diagnosed and managed right away. Although rare, serious complications may arise from an infection in the jaws. You could get a rapidly spreading infection to the face or worse yet, brain, and you will require hospitalization if this happens. You should find a dentist right away.
