Your tooth might be loose.
It could just be a loose tooth. If it has a hole in it, then it's a cavity. Next time you go to the dentist, I would tell them about that.
I have the same thing now. Went to the dentist. Said not a cavity. Food goes under your tooth and will not come out until the tooth itself comes out.
