I went to dentist b/c part of my tooth filling came out. While the dentist was filling my tooth, I felt pain and I was given another injection. During the filling I was about to lose my consciousness and the dentist wanted to me to stand up and I rinsed my mouth with water. It has been 1,5 months and I can't eat anything with that tooth that is harder than a french fry. It feels like I can even feel the nerves of that tooth. I prefer to eat with the other side. What might be the cause of this pain and what should I do? Should I trust the same dentist again? I greatly appreciate your help.
