HELP... I think I might have broken my tooth?

I was eating popcorn and I bit down on a piece of a kernel (It wasn't a whole kernel, just a piece of one). The piece of kernel broke and made a loud cracking sound. I looked at my tooth to look for a crack and touched it with my tongue to look for anything sharp but I didn't find anything. It doesn't hurt and I even drank cold water to see if it would hurt, but it didn't. Does it sound like my tooth is okay or could it still be broken?
