Yes, a shot of Novocain can damage a nerve—
but the bigger question is if this
can be permanent.
“The needle used for the injection could ‘brush’ the nerve and ‘traumatize’ it, says Laurence (Larry) Grayhills, DMD, MS, MAGD, member of the Academy of General Dentistry.
“However, I don’t believe there has been a reported case of permanent nerve damage from an injection. Novocain is not used in dentistry anymore due to its allergic potential. I am not aware of any nerve damage from the medications currently in use (i.e., Lidocaine, Articane, Mepivicane, etc.).”
