Here's the thing, recently, when I'm eating something, the two molars in my mouth hurt. And I've been told before I had cavities. I haven't been to a dentist at all I think, except for one time, to remove one of my teeth because it hurt. I think it grew back, but not sure. My teeth are crooked are aren't the best. We don't have health insurance, so we can't go to the dentist. I'm 16. I brush my teeth two times a day and use rinse once. I don't floss. What should I do? And also, the two molars currently are feeling uncomfortable and hurts a little.
