I have a mildly swollen area in the back of my mouth, right above one of my wisdom teeth. It seems like the gum behind it has moved above the tooth, and there is a small white pimple on it. This leads to pain when swallowing. I have used Listerine for the past few days, but I feel this has only worsened. I am currently on vacation and do not know whether to do something about this now or whether to wait until I return to my country next week.
Please help me.
