You can deaden a nerve with an injection of local anesthetic:
- near the small nerve branch going inside the root of a tooth.
- near the main nerve trunk before it divides into small branches.
Smaller nerves branch off from the main nerve — much like branches of a tree leave its main trunk.
One small nerve then goes to each root of every tooth.
