pain in upper and lower gums.?

its not to the point where its excruciating, but its getting there..even tylenol is not helping the pain subside. what could be causing it? Im 21 I havent yet had my wisdom teeth out..could that be the case. What a bad time to be stuck without dental insurance! :(

Is there any chance it's gum disease? Do you floss once a day? Use any mouthwash? If you don't already floss and use mouthwash, I would start flossing and using Listerine Antiseptic. It could be your wisdom teeth coming it. Rinsing with warm salt water can help calm the inflammation. Try rinsing with it before you brush your teeth. If these things don't work, then I would see a dentist. Some medical insurance will cover wisdom teeth removal in certain circumstances.
