I have tried rinsing with hydrogen peroxide and antiseptic mouthwash, these numb the pain temporarily, but do not really aid in healing the sore. The spots
always look similar to this one, they are raw looking and red
in the middle, and look yellowish-white on the edges. They have always come one at a time, I've never had more than one on my tongue at the same time. They are usually about a centimeter big, and oval shaped.
