Proper use of articaine and epinephrine

Before you receive the injection, a numbing gel may be rubbed onto the gum to make the injection more comfortable.
This medicine should cause numbness only to the area where it is injected. You may experience temporary loss of sensation or movement in the injected area. This type of numbing procedure is called local anesthesia. It is not meant to cause you to fall asleep or become unconscious.
Your mouth may be numb for several hours. To avoid injury after dental work, do not eat or drink until normal feeling has returned to the area. Do not test the feeling in your mouth by biting or poking the treated area.
