she's mine now. i took her to the vets, she has a incisor root growing through her chin. we need to put some weight on her first, she only weighs 450g and is very skinny. she's been put on baytril and metacam and once she's bulked up a bit, she'll have an xray to determine where exactly the root is. then she'll need a surgery - hopefully they'll be able to do that depending on the root position - and if all goes well, she'll always have dental problems. but hopefully we'll be able to get her better.
