I have a lump at the top of my gums at the begining of the month I went to the dentist to see what was causing pain in a tooth they said i had a chiped tooth that would need a root canal and someone was going to give a deep cleaning for an infection that i had they gave me dental floss when I left and said to floss and not worry about if it bleeds it is just draining out I don't have gingavitas or a tumor because they also gave me x-rays but now there is a big lump on the top of my gums on the right side of my mouth I have tried poping it but it is very moist and a hard part to get to in the mouth I used a safty pin and tried a meat knife by just pushing on it to see if it would pop I was wondering if you would know what it is or have any advice to get rid of it
