Sinus Headache & Tooth Numbness: Understanding the Connection

Sinus headaches typically don't cause teeth numbness.

However, teeth numbness is a common symptom of trigeminal neuralgia ("tic douloureux"), which is a chronic facial pain disorder. Trigeminal neuralgia affects the trigeminal nerve, which is responsible for sensations in the face including your teeth, cheek, and forehead.

It is important to see a doctor if you are experiencing teeth numbness, especially if it is accompanied by other symptoms such as facial pain, headache, eye pain, or vision changes.
