Teeth?

Baby has all the symptoms of teething and when I rub her gums I feel a solid spot on her bottom left gum.. did screenshot these from a video so their not the best quality.

But when I rub my finger along the hard bit I can now see a white line sort of looks like an outline of a tooth just under the surface?

Tell me I’m not crazy 🤦🏼‍♀️😂
