Inside mouth on cheek

Parasites Forum 01 See, Need help with multiple parasitic infestation, please! - Totally gross, I know!!! What the heck is this?! The stringy portion ends at the front of my mouth. It moves, and I have broken the skin and pulled out a wormlike substance, approximately 3 inches in length. I brush my teeth three times per day and after healthy meals, rinse with listerine after each brushing, and stay away from sweets. It goes away, but soon returns. I have a list of other problems along with this one. Please see my post, and help!
