Will my tooth fall out after trauma?

I got hit in the front tooth. One of the big ones right in the upper front. It was knocked inwards, but I pushed it back in place right away. This was about three weeks ago. It hurt a little still, and a tiny bit wiggly. But I think it's healing pretty good. But I looked at it and the gums around it are a little purple. I'm so scared it will fall out. I haven't been to the dentist yet.
