I noticed that on the back of my mouth, the gum is swollen.... There isnt any white spot on it. I gently presses my swollen gum with a q-tip today and it was very sore. I was thinking if my wisdom teeth is coming out. But I am only 16 years old. Everytime I yawn, my left side of my jaw hurts. When I closed my mouth, it just feels like a bump. Oh I just got my braces about 3 months ago. I was just wondering if its an infection, wisdom teeth or something else? What can I do? Should I go to my dentist?
