Dental problem?!

Dental problem?

I visited the dentist 6 days ago for a simple filling. He injected the inside of my cheek tissue with an anesthetic. When he tried to work I felt some pain, so he injected again. He had to do this 3 times and I still had some pain!!. He then was telling me that he will go for the tooth with the needle (I guess it means injecting closer to the tooth). After that I did not feel pain while he was working. seven days after that visit, I still have some strange feeling in my mouth. When I am trying to open my jaw wide (eating an apple) I feel some pain. When I looked in my mouth I saw that there are some white color pimples in the inside tissue of my cheek. Is this serious, or will it go away in few more days?

I believe it will go away. He loaded up up with quite a bit of painkiller. If you don't feel an improvement by Monday, make an appointment for a follow-up visit to be sure.
