How old are you ? 12 ? And gorgeous ?
She could have got a brace, just so people like you wouldn't laugh at her ?
I don't need to lighten up, thanks. It doesn't seem like you are the last person to laugh at anyone.
By all means, laugh at people for their behaviour, dress sense, their menu,their cooking skills, but not at their physical (mis)fortunes.
BTW, I didn't find her teeth a problem, it is part of who she is and she wears them well, so to speak.
Now if they were all rotten or gold plated, then I might have chuckled - in disgust.
