Nerve injuries after dental injection: a review of the literature

Prolonged and possibly permanent change in sensation due to nerve damage can occur after dental injections. Although the condition is rare, many practitioners will see this form of nerve injury during their careers. The exact mechanism of the injury has yet to be determined, and little can be done to prevent its occurrence. This type of injury carries with it many functional and psychological implications, and referral to both dental and medical specialists may be necessary for continued follow-up and possible treatment.
