2 weeks ago my 3 year old fell and knocked her 2 front teeth. Her gums bled a tiny bit and she got a bit of a swollen top lip for a couple of days. She said it hurt to bite down on hard things later that day but is otherwise has been fine. It’s been not wobbly or moved but today we noticed one of the teeth is slightly grey. Wondering if anyone has experienced similar and what happened please? Will it get darker or fall out? Or whiten up? X
