The medical term for this affliction is called tonsilloiths. These little nuisances can be a real pain because they gather very easily in the crevices and pockets of the tonsils. What's interesting is that they can still occur even after the tonsils are removed. The tonsil is a very sensitive thing and when it is filled with food, dead skin cells, mucus and bacteria it becomes a great place for tonsil stones to grow and populate.
