White thing sticking out from tongue?

A couple weeks ago I was brushing my teeth and I noticed this white stringy looking little thing stinking out from tongue and at first I thought it was food or something my toothbrush left behind but I touched it and started to pull and it wouldn't come out. Now I have no idea what it is. I thought it was just something that would go away eventually, but it's still there. It's like a mini "bone" or tissue, I have no clue but every time I pull on it, it hurts. I was thinking about cutting it out but I'm really scared to lol I don't know if it's something serious or not, but it's just sitting there and I don't know what to do. Anybody have a clue on what this could be?
