Tooth feels loose? It's a permanent tooth?

Ok, so randomly one of my bottom canine teeth feel wiggly and kind of sensitive. I don't know why, i havent had any accidents like hitting my tooth or anything, and i dont think i grind my teeth while sleeping. I'm not positive if it is for sure wiggling, but it feels like it. If it is, i tried to see if it was and i cant feel a huge difference but it just feels weird... i brush my teeth daily and use dental floss and mouth wash so i dont have dirty teeth or cavities that i know of. what could this be? is this normal and will it just eventually feel normal again?
