How To Treat Swollen Red Incisive Papilla?

I have a swollen red Incisive Papilla that will not go away. I saw a dentist recently, who said all xrays were good. He said nothing was out of the ordinary, but did some cleaning around my two front teeth, to see if that would help. So far no. Still is sore and burns somewhat when my tongue touches it. Is there anything I can try at home, as I can not afford a oral surgeon at this time. My research on internet said it could be an Incisive Canal cystic lesion? Thanks for any help! ( My body usually heals itself fairly quickly, as I have never smoked, drank etc. but this one has me stumped!)
