Root canals are needed when decay and bacteria spread for too long without treatment. At a certain point, this decay makes it to the pulp inside the tooth. This pulp includes nerves, therefore infection generally causes a lot of pain. Since this is happening on the inside of the tooth, you won’t necessarily see the damage. Instead, you could feel it through pain and notice other signs that include bleeding, swelling and bad breath.
