I think my tooth is fractured

[Rubagonya]

I whacked my tooth awhile ago and just realized a crack inside my tooth. I the trauma from the time I hit my tooth I know that had to be when I did it. Which was four years ago. I have only received one bit of pain just today and I am wondering what to do. It is inside my front tooth and I it is a horizontal crack from one side to the other. I am pretty sure I cracked the dentin. I am fearing that there is nothing I can do considering it is inside my tooth. My biggest fear is that is ight change color as well. What should I do?
