Internal Medicine

Numbness in the upper jaw is often linked to problems with the trigeminal nerve, which supplies sensation to the face. Possible causes include trigeminal neuralgia, dental infections, nerve compression, sinus issues, or, less commonly, an acoustic neuroma (a benign tumor on the nerve near the ear). Because jaw numbness can range from minor to serious, a professional medical evaluation is essential to identify the underlying cause and determine the right treatment.

Explanation

Numbness in your upper jaw can be caused by problems with the trigeminal nerve, which is responsible for sensation in the face. This is known as trigeminal neuropathy. It can happen due to various reasons, including injury, infections, or other conditions affecting the nerve.

Another possible cause is an acoustic neuroma, which is a non-cancerous growth that can press on nerves in the brain, leading to symptoms like numbness in the face or jaw.

It's important to talk to a healthcare professional if you're experiencing numbness. To better understand your symptoms and get personalized insights, you can take a free symptom checker test that can help guide your next steps for appropriate care.
