Why do I have a canker sore on jaw?
I've tried using salt water to rinse my mouth but it hasn't helped much.
You can also try applying a mixture of equal parts hydrogen peroxide and water to the canker sore a few times a day. This can help speed up the healing process. It's also important to avoid irritating the sore by avoiding spicy or acidic foods and using a soft-bristled toothbrush to brush your teeth. Does that help?
