Large hole in my cheak after wisdoms extracted is this normal it looks torn and its large enough for the tip of a pinky to be put in it. Its painful and uncomfortable.normal you or no

Not your cheek, your gum, right?
It's normal. They don't stitch gums shut anymore after tooth extraction.
You should have a page of instructions for how to take care of it for about a week or two. If you don't, Answer below, because it's important.

There should not be a hole there, after the tooth was extracted there should have been placed some wadding for you to bite on for 30 minutes so that the blood would clot. Dry sockets are a fairly commonplace complication associated with having a tooth extracted. Their occurrence is associated with a situation where the blood clot normally expected to occupy the extraction site and initiate its healing has instead been lost. The net result is that the healing of the socket becomes delayed. It is also commonplace that dry sockets can be incredibly painful. I would make an immediate appointment with your dentist. If this is the case he will scrape the edges of the cavity to cause it to bleed, place some medication in the hole and stitch it up.
