its been about 6 week now that i noticed that between my upper and lower wisdom tooth theres this bump that gives the appearance to a plica fimbriata .i know that only is in the floor of the mouth but thats the appearance of it.the tip of it sticks to my finger whenever i touch it.i went to see he dentist but shes mot sure what it is.she told me it could be because my lower wisdom tooth is impacted.she reccomended me to go to uic dentistry universty to get a biopsy .but they want to charge me 200 plus dollars.so ill wait to get an intern to look at it becssue it will be much cheaper but have to wait till march to get my biopsy .anyone knows what this could be?i know i askv) this so much but could it be hpv ?im sorry but im so anxious about it. thank you so much in advance .
