my tooth smells funny?

my wisdom teeth came in but one of them is sideways, and i can't clean it properly. it's was getting dirty/dark looking in the cracks so i'd just put mouth wash on it. but now I swear it smells funny, it doesn't hurt. but it smells... is there something that i can put on it to help it out, I don't have dental insurance

how do you smell your own teeth ?
