answer:Sometimes I get food or something stuck in between my teeth and my gums , like a popcorn kernel. The area will become inflamed, and painful. I kind of just brush the painful area alot and then eventually, after a week or so it goes back to normal. That being said. Depending on your age, health, and family history, you should maybe be evaluated if you have head pain that affects your vision. (Assuming you don’t have a history of migraines. ) There are a few things to rule out if this continues. If it isn’t a big inconvenience, monetary wise, or work wise, I would speak to your primary care physician. Good luck. Peace n love.
