What are the typical symptoms of nerve damage after wisdom tooth extraction and how long should they last before seeking medical attention? Could they indicate more serious complications if they persist?

Nerve damage after wisdom tooth extraction can result in a variety of symptoms, primarily due to the proximity of the tooth roots to sensory nerves such as the inferior alveolar nerve or lingual nerve. These nerves are responsible for sensation in the lower jaw, chin, tongue, and lips. Common symptoms of nerve damage after wisdom tooth extraction include loss of sensation or numbness in the lower lip, chin, tongue, or gums. This may feel like “pins and needles,” or the affected area may feel completely numb.

Some patients may experience a tingling sensation, similar to when a limb “freezes.” This occurs because the nerves are irritated but not completely severed.

While pain may be common after tooth extraction, nerve damage can result in abnormal or persistent pain. This pain may be sharp, burning, or aching, and may occur even in the absence of other symptoms.
