About my cracked tooth...

I probably should of already asked this when I asked my other questions about my dental issues, but I forgot lol
On my cracked tooth *which is located in the back*, it's not completely gone at all. The middle is sort of gone... what it looks like is a...

tooth with a rather large hole. But the crack part looks kind of... brown. Is this my tooth's roots?! Or is this just how cracked teeth do?
Does this sound really really bad and unsavable? Or does it sound like it can be saved? And no, it doesn't hurt at all. Never has actually. Pretty much what I'm asking is do you all think my tooth will need to be pulled or not? And if so... what will happen? Will I look weird? I really don't want it removed =/
Thoughts/help would be much appercaited.

It proboly won't get removed just go to your dentist,tell them what happened. And they proboly can fix it with a filling.

Probably need a root canal, Crown lengthing, post and Cap. But they can probably save it.

I have a bad tooth too. Over half of it is missing and there's nothing in the middle. I'd sooner get knocked out and have it pulled though. Lol. I'm scared of dentists.

I'm scared of dentists too. That's why I've never been to one lol
But now my parents are making me go just as soon as possible. I'm like ahhh! NOOO! lol
I'm so scared/nervous. But I'm super glad to know it'll probably be able to be saved. How about cavities? Do they ever cause the tooth to be removed? And if so, how bad do they have to be for that to happen? I want to know since I have a couple cavities too.

I thought I'd update my last comment. I have to get sedated and they'll be pulling my tooth out. It's scary because I might still be awake. I've never had a tooth pulled before. I hope they weren't lying when they said I won't remember anything. 0_o
