Well, they haven't gone away. I stopped using Crest White Strips and I've just been brushing my teeth with baking soda, no peroxide. They just get really red and irritated everytime I brush and they feel funny, kind of loose in my mouth. It spread a little bit to some other parts of the gum, and my gums burn alot when I use toothpaste, like how it feels when you burn the inside of your mouth from hot food. My regular dentist won't see me until September. Should I go to an emergency clinic or something? It is only a few days before my period, and typically, my gums swell and get sore before my period, so this might be affecting me too. Argh. Your ordeal sounds harrowing! I wish you lots of luck.
