instruction: hello doctor for the past week I had gotten a small round bump on my lower gum it is just in the corner at the lowest part of the gum so I have to pull my mouth open with my fingers just to see it does not hurt or bleed but it has not gone away and it has gotten a whitish color to it I also got the soreness on the tip of the tongue this morning I am quite careful with my teeth and brush or rinse regularly every day so I am confused to what may have caused this morning I woke up with a redness on the tip of my tongue too I wonder if it is because I have poked the bump with it just to feel wether it is still there I have switched to peroxyl mouthwash to see if this may solve it can you advise me on what this maybe I am a little worried
