Can you tell me how dentists numb your mouth?

Local anesthetic. : Normally the dentist will use a local anesthetic like Lidocaine next to the root of tooth or location near the nerve trunk to numb teeth and gums. A topical ointment is often rubbed on gums prior to the injection to take the sting out of it. The shot will numb the area for several hours. Caution must be taken after the procedure to not injure the numb area.
