Hi Dr. Rynne. Thank You For Assisting. I Have A

Hi Dr. Rynne. Thank you for assisting. I have a very small lump inside my mouth cheek on the left side, in the middle approx. It is very small, hardly visible, blended in with the skin color and does not ever hurt. It is not filled with anything, simply skin colored. I have been grinding my teeth lately and I have had it for about a month now. What may be your assumptions ? Many thanks !
