What could cause numbness inside my mouth, particularly in the cheeks?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Numbness in the mouth, particularly in the cheeks, is most often caused by nerve-related issues or trauma from recent dental procedures. Other possible causes include infections, allergic reactions, vitamin deficiencies, or underlying neurological conditions. Because the trigeminal nerve controls sensation in the face and mouth, any irritation, inflammation, or injury to this nerve can trigger numbness, tingling, or a "pins and needles" feeling in the cheeks.

Since cheek numbness can stem from many different causes—some minor, others requiring prompt medical attention—it's important to identify the likely reason before deciding on next steps. Taking a free, instant, online symptom check can help you quickly narrow down possible causes based on your specific symptoms, giving you clearer guidance on whether to monitor at home, see a dentist, or consult a doctor.

Explanation

Feeling numbness in your mouth and cheeks can be concerning. Here are some possible causes based on the provided references:

Nerve Issues: Sometimes, numbness can be related to nerve problems, such as those affecting the facial nerves. These issues might be associated with conditions like carotid artery problems. Nerve-related numbness often requires medical evaluation to determine the underlying cause.
Dental Procedures: If you've recently had dental work, numbness might be due to trauma from the procedure. This could happen if the tissues inside your mouth were affected during treatment, such as when receiving anesthesia.
Other Causes: Although not detailed in the references, it's important to consider that numbness can sometimes be a sign of other health issues, so it's a good idea to talk to a healthcare provider if the numbness persists or is concerning.
