I was hit in the mouth two weeks ago and one of my front teeth was knocked very slightly back. I could not close my mouth all the way for a week and even now I find it uncomfortable to bite down on food. The tooth is just a little bit darker than my other teeth. I have no insurance or money to go to the dentist. Will teeth like this heal on their own? Will they rewhiten or stop being sensative after time? I know I should go to the dentist, but I can't. So, what are my chances of self-healing?
