Help! First wobbly tooth came out, but not the whole tooth...

[SquishySquirmy]

Should I be worried?
DD was twisting her tooth (which has been wobbly for ages) in the bath. It came out, but it is assymetrical, jagged at the bottom and looks like it's broken off. DD is really excited, but I'm a bit concerned about the bit of tooth that must be left in her gum. Will it work its own way out? Or is a trip to the emergency dentist needed?
Has anyone had this happen to their child?

What I feel really, really terrible about is that the tooth did have some signs of plaque/decay and she's overdue for a dentist appointment. we are really careful about brushing (though maybe focused on the back to the detriment of the front) and she rarely drinks anything other than water.

It's a front tooth, and the "bad patch" is sort of chalky (not brown). I suspect this has contributed and I feel awful. It's her first wobbly tooth.

Go to the dentist.

Are you sure that there is a bit of tooth left? The way baby teeth fall out is that the root underneath the gum gets resorbed by the body leaving behind the enamel crown of the tooth which can look like a little jagged sharp edge. The reason the root of the tooth gets resorbed is because the adult tooth is growing underneath and needs space to grow. If there is anything left it's likely to work itself out or disappear as the adult tooth comes through. Sounds like she would benefit from a check up though so you could get it checked out if you're not sure.

Thanks for responses.
I will be getting a dentist appointment anyway, but just wondered whether this was an emergency-take-monday-off-work-scenario or not.
Should have mentioned I did call nhs 24 for dental advice, but there was noone available and I haven't had a call back yet.

Nomeslice that is really interesting about the reabsorption, and is why sometimes asking a question is so much better than googling! (Which I did try).

The weird thing is that I thought that primary incisors just had one root, but on this one what looks like the root is sort of off to one side if that makes sense. I couldn't see if there is anything left in her gum, because the hole is full of blood. There is the new tooth coming through just behind, but I've been able to see this for a while.
