Hey guys, not a troll, promise, just inexperienced in this area. I have never had a cavity before. I was raised by my grandma who is a retired dental hygienist so I have always had good oral hygiene, brushing after each meal with a soft brush, flossing twice a day, and I have always known what proudcts to use, etc. I don't want to call her and tell her because I don't want to upset her, given she is a former dh and all and will get pissed at me. For some reason, I woke up yesterday morning and one of my lower incisors hurt. It was quite tender and was sensitive to touch and felt sore, as if I ha just had braces installed in my mouth. I woke up this morning and it was a noticeably better, but I took yesterday off and don't want to take another off day from running. What are your guys experiences with toothaches and running with them? Does anyone know what this can be? Should I go on my run today or will running just exasparate it? Thank you.
