I'm scared to get it checked, but I've had a bone sticking out of my gums for weeks.
A bone or a piece of tooth? Either way that sounds dangerous to your health.
I'm thinking this is nothing serious, but if my tooth is in danger then I might need tooth surgery or I might die.
This sounds like a really bad situation for your mouth to be in. You really need to go to the doctor right now, not later.
I don't think I need to go to hospital.
It might not hurt right now but you'll be in a lot of pain if it gets infected, so please get it checked out sooner rather than later.
