Between each tooth is a little space that extends ever-so-slightly up within the gum line between the tooth and the bone. It's called a gingival sulcus. This little space size should measure somewhere between one and three millimeters deep.
Sometimes, usually due to poor dental cleaning, a sulcus can become larger or deeper, like five or six millimeters deep. When that happens, it then becomes what's called a "pocket". You never want your sulcuses to become pockets.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
