I just had a check up with my MO and everything going fine........ Then the next day I felt a bump on my gum, on the left lower front. At first I thought it was a piece of food stuck to my gum, it's about the size of a pinhead. It didn't go away, so I took a look---it is between two teeth on the gum and it is pale with a greyish center. And I am totally freaked out by this. I have never had dental problems, so I am not familiar with anything it could possibly be, besides you-know-what. It aches a little bit. I will see the dentist on Tuesday, but in the meantime while I am freaking out anybody have any ideas about what this could be, besides what I am afraid it is??
