Well, I think it's rotten. DD (8) has complained about sore tooth for about a week - I thought it was loose :(
I looked at it tonight and half of the thing is missing and black near gum. I actually can't tell whether it has broken because of biting on something hard (I asked if she had opened a lid with her teeth- she says no) or whether it has literally rotted away :( :(
The thing is, I look at her teeth regularly and have not seen any sign of this coming.
Can this really happen within the space of a few weeks?
