My front tooth was chipped real bad. One side is black and other is white. Do you think a root canal could fix it?

Sorry to hear about your fall. It sounds like the nerve inside the tooth died and because of the trauma, it turned black. You probably need a root canal treatment, which it cleans out any dead tissue inside the canal of the tooth. For cosmetic options to take care of the discoloration you may consider doing internal whitening , and porcelain veneers. Think about what works best for you and all the risks and benefits, most patients do the conservative approach of whitening. 

If the tooth is black, it most likely was so traumatized by the event that chipped it and the nerve died.  Oftentimes if a tooth sustains a bad blow, or the infection goes on for a long time without being treated, the tooth turns black.The root canal might save the tooth, but it by itself will not turn the tooth white again.However, most severely chipped teeth that have had root canals need full crown restorations, and a new crown can be made to match the color of your other front teeth.  Thus, the blackness underneath the new crown would not be visible or a problem.
