You could be describing my Dd! She is only 5 and already has lost 5 baby teeth, she is terrible, will leave them and leave them, one had completely turned the wrong way round and she couldn't eat anything all afternoon, luckily it fell out while she was asleep!
She won't let anyone near them, she would go beserk, losing them at night means she has swallowed all but one, she has to leave notes for the tooth fairy!
