<human>: A little back story: A few months ago I got elbowed in the face during a game of soccer and shipped my two upper front teeth. I had to get caps put on them and one of them has been loose for the past few days. I was supposed to go to the dentist in 3 days to get them fixed so I just ignored it.

As to my TIFU, tonight I was making brownies for my nieces and nephews while I was baby sitting them and sneezed and did not cover my mouth. I did not know this at the time but the cap that was loose flew out into the mix. Fast forward 90minutes of me panicking and looking for the cap, the brownies are good and cooled off so I serve them to kids and about 30 seconds later I hear a faint crunch and my 12 year old niece starts screaming Hysterically and yelling that her tooth hurts, she spits into a napkin and I find MY missing cap and a pretty good piece of her tooth. Her mom (my sister) took her to the dentist the first thing in the morning and we find out that er tooth was one of her "adult" teeth so pulling it was not an option so now my 12 year old niece need a cap on her tooth because of my cap.

Moral of the story; cover your mouth or at least turn away if you sneeze/cough while cooking anything.

Provide a brief overview of the text.
