This happened with me when I was in first standard. I had a milk tooth which was shaking for a long time but it just wouldn’t fall.
My friends and parents knew about this but couldn’t do anything. One of my friends thought of a plan. He asked me to meet him during lunch break. It was a prank set by him. When I came out, I slipped on a banana peel and fell down the stairs.
The fortunate thing was that a tooth broke but the unfortunate thing was that it was not the troublesome tooth. My shirt was full of blood. We went to the School Dispensary very next hour and got the troublesome tooth removed.
