<s>[INST] I have a piece of skin like flap hanging from the inside of my upper left cheek. i thought i just bit it eating but its a little higher up the cheek to have come from a bite. i can wiggle the little flap with my tongue, what is this? will it go way on its on? [/INST] Thanks for your query, I have gone through your query.The skin like flap over the cheek is nothing but a inflamed salivary gland duct which is present at the level of upper second molar. Nothing to be panic, consult a oral physician and get it evaluated. Mean while you can take a course of antibiotics like amoxicillin. Do saline gargling and drink lot of water.I hope my answer will help you, take care. </s>
