When will the pages be re indexed by Google?

Hello friends,
As I was working on one of my site and accidently I have uploaded the file having no indexed Meta tags and due to that my site pages are out of Google search. I have removed the no indexed Meta tags but now I want to know when will my pages be re indexed? And will it again start indexing from the scratch?
Thanks

If you want index your site you have back link of your site and ping it.

Basically Google index a website within a weak. So, don't worry your site will index again when Google crawl your site.Depends on your site statistics is important.
