A few days ago my gums seemed to become really inflamed and started bleeding out of nowhere. Now every time I brush my teeth, or slightly knock my gums they bleed. My gum has receded a bit on the top too and I'm really worried as I can't get to my dentist for another 3 weeks. I brush my teeth twice a day, and bought a mouthwash for gingivitus a couple of days ago to try and alleviate the issue, though it hasn't done much yet. They're still really inflamed and bleeding, and I'm worried as I'm only 20!
What else can I do?!
