Last December, I visited dentist to inspect my oral hygiene.

Long story short, dentist told me one of my wisdom tooth came out at an angle.
He explained the effect and consequences if did not extract it.
Well I am fully aware of the wisdom tooth that is jutting out and most of the time I have food stuck in between there.

After making a swift decision, I thought of getting the tooth out to prevent food from stucking. (my biggest concern)

Now it's almost one month+ since the wisdom tooth is extracted, there is a small hole left open from the incision.
Currently I am facing the same concern again, which is having food particle stuck behind my mouth.

Would just like to know, is this normal?
Will the hole closes after certain time?
Any solution to it?


Extra info: Extraction cost 1k, second most pain I experienced
