Unforuntately, this isn't my first time around with toothaches and root canals.. I have already had 4 previous ones, and need two more after this one is done. The dentist has been the same one I've been going to since i was very young, so I trust his work. He always gives me a perscription for vicodin, but i am really hoping I won't need it, because it always ended up making me feel sick to my stomach.
