Right side of inner mouth sore

what can this possible be? Its been a week now, some signs of healing . first presented as an earache on the right side, then swollen gums, then that subsided and just this left for a full week now. please helppp

any ideas pls help

If it is truly healing, then try something for the pain. I do believe that you need to try salty water. Avoid very cold and very hot drinks and water.
