Where to Inject

In this chapter:

DENT Ch9 Page 136-1.png

You can deaden a nerve with an injection of local anesthetic:

  1. near the small nerve branch going inside the root of a tooth.
  2. 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.
