I just had 2 cavities filled; my top left molar and the one in front of it. A few days after, it was still wicked sensitive which I didn't think too much of, I figured it would take like a week or so to go back to normal. Well now it's been more than like 2-2 and a half weeks and they are still VERY sensitive. Nothing too hot, nothing too cold... And even when I breathe in cold air, it kills. The pain goes right up my cheek. It's beginning to become unbearable. What could it be? Did my dentist drill to deep and hit the nerve?
