The authors reviewed 12 cases in which altered sensation occurred in the distribution of the inferior alveolar or lingual nerves following injection of a local anesthetic for restorative treatment only. Most patients suffered only partial damage, but recovery was poor. The exact mechanism of the nerve damage is unknown, but a number of theories are proposed. The extent of this problem is also unknown, but many more cases probably exist than have been reported to date.
