I think the acidity in Mountain Dew is getting to me. I have multiple mouth sores. Two from biting my lip, but a couple more that I can’t pin down. They could be from eating sharp foods that stab my gums. Maybe the acidity is just slowing down the healing process. I also noticed yesterday that one of my glands is swollen below my jaw. Good times.
I’m not sure why I bite myself, but I do notice that it happens almost exclusively when I chew with my mouth open.
I normally chew with my mouth closed, but every once in a while something causes me to open my mouth and… BAM! You’d think my teeth were just waiting for the opportunity to attack my lip. I don’t know what my lips ever did to my teeth, either…maybe something while I’m sleeping.
