Sorry for the delay, been a little busy..
She's 6 months old. After closer inspection, the tip IS chipped. But she still shows no signs of pain. I called her vet and she told me to keep an eye on it. As long as there's no swelling, redness or signs of an abscess, she should be ok and it'll fall out when her adult tooth comes in. So I've been checking it every few days to be sure. If it doesn't come out soon I'll be making her an appointment to see if there's anything they can do.
It was just very odd to me as I've never seen a puppy tooth do that.
Any advice on prevention of this happening to her adult teeth would be greatly appreciated.
