I don't know what this is but i'll just call it bubbles. It's not kankasore or swollen because it's not red or sore/hurt. It's like a big bump/bubbles in my mouth. I probably get it when i brush/floss my teeth hard and it bleed and most of all i ate papaya salad i guess i got infected by that so i think that's where i get the bubbles. how do i get rid of it and do u guys get it too. Is it normal? not disease right? thannks for the reply
