Hello, I am nineteen, had all four of my wisdom teeth out over a year ago and now all of a sudden am experiencing a soreness behind my left molars. My cheek and jaw are a bit sore two, as well as the corner of my mouth getting sore and irritated. I have no idea why. The only thing I can think of is my teeth may be moving? I have never has braces so I'm not sure if this is why. I have slight crowding in my bottom teeth, I don't know if that helps. I have also just started using this 5-minute speed Whiting Kit. Is this causing the pain/inflammation? Maybe I'm allergic. Please let me know if someone can help. THANK YOU!
