Different places : Injections are usually placed next to the tooth that the dentist wants to treat. This type of injection is called an infiltration. Another type of injection is called a nerve block. This is when the dentist injects the anesthetic in close proximity to a particular nerve. This usually results in a larger area of the jaw being numb.

Depends on the Tooth: For upper teeth, the injection is normally right next to the tooth, on the outside, where the cheek/lip is. For surgery, another injection on the palate is needed. For lower teeth, the injection is normally near the back of the mouth on that side, where the jaw bone starts going up towards the ear. There are other types of injections also. It depends on the tooth and the planned procedure.
