What are the potential causes of numbness on one side of my face?

Numbness on one side of the face happens when the nerves that supply sensation to that area are affected. Some common causes include:

Nerve irritation or damage: This can occur due to infections (like shingles), dental problems, or inflammation of the facial nerve (Bell’s palsy). Stroke or transient ischemic attack (TIA): A sudden numbness could be a sign of a stroke, especially if accompanied by weakness, speech difficulty, or vision changes. Multiple sclerosis (MS): This condition affects the nerves and can cause facial numbness among other symptoms. Migraines: Some migraines cause neurological symptoms including numbness or tingling on one side of the face. Other causes: Tumors, trauma, or certain medications can also cause facial numbness. Because some causes are serious, especially if numbness is sudden or accompanied by other symptoms, it’s important to seek medical attention promptly for proper diagnosis and treatment.
