Non-rotting nerve: severe pain appears as a result of poisoning the nerves and the pulp in general with the beginning of the secretions of germs.
Rotting nerve: It comes at a later stage when the teeth are neglected, as germs affect the pulp of the tooth through the toxins emitted from it, and lead to the disintegration and rotting of the pulp with its nerves and blood vessels.
The treatment of a rotten tooth is different from the treatment of a non-rotten tooth. The treatment of a non-rotten tooth needs local anesthesia to remove the nerve from it, and it is done most of the time in one session, while the treatment of a rotten tooth needs multiple sessions until the germs endemic in the tooth are eliminated, which is It does not require anesthesia in some cases.
