On the right side of my teeth, just behind my last molar my gum is swollen. The swelling is not red (its the color of healthy gums), and has pus (I assume, because I have a constant bad taste in my mouth). When I close my mouth, I can feel it hitting my top gum. The swelling popped up virtually overnight, and is in just that one spot. It has a throbbing feeling and slight pain on the right side of my jaw and the swelling is just barely over the edge of my back molar. I have no difficulty opening/closing or moving my jaw in any way. My throat just barely aches on and off, like that just-before-you-get-a-cold feeling. All of my adult teeth have grown in. I thought it was gingivitis, then thought that it had something to do with wisdom teeth, but Im only 15. I have braces. Im female and 15 years old. Should I see the dentist?
Hi, as your gums behind the last molar is swollen it suggests of peritonitis or may be the last molar is erupting, and also you feel pain in your throat that could be a reaction of your immune system to 3rd molar eruption. You please star warm saline gargles 2-3 times a day and also consult your dental surgeon in the meanwhile you can take some painkiller for relief.  Wishing for your better health
