What is a root canal anyway?
There are many steps in the procedure we call endodontic therapy, but
basically the space where the nerve lives inside the tooth is accessed and
the nerve is removed. Then the entire network of canals is prepared to be
cleaned, shaped, filled and sealed to prevent blood and other bodily fluids
from leaking back up into the canal. This is done so the tooth may exist and
function in your body with no discomfort.
