It's like a brownish color and its smaller. I can feel it when I put my tongue on it and press down. I can also feel it with my finger nail. I can put a little bit of a sharp thing in it as well. WHAT SHOULD I DO?! I don't want to be embarrassed by my dentist or him yelling at me Cuz I just got my braces off and I'm already going there again when I just got 2 fillings done!! I'm 13 by the way.
