Losin' it for everybody

I am having a Lady MacBeth type issue where it always feels to me that there is something stuck between my upper right canine and its accompanying bicuspid. I have flossed about five times a day for the past few days, and can confirm with mirrors that there's nothing there. Only I can feel it and it's there. And sometimes I do manage to seem to suck something out - only, two seconds later, it's back to feeling like there's something in there...
