I've had this canker sore for over a week now. Mine usually last 3-5 days so I've very pissed off! It hurts to talk and to eat, to brush my teeth, to drink, everything! Uh, any tips on how to make it go away?! Every couple days it gets smaller and I think it'll go away but then it comes back full force!
ugh, the worst. when i get them i gargle with hydrogen peroxide 3x a day. swish it around your mouth and concentrate on the sores... it gets fizzy and feels gross, but spit it out, don't rinse. it makes mine go away within a day or 2, max.
