How Does Tonsil Stone Form?
Tonsil stones are formed when food particles get trapped in the deep tonsillar crypts and are acted upon by the digestive enzymes present in saliva. These food particles get broken down but some hard particles get left behind in the crevices in the tonsil. Over these remnant food particles, layers of bacteria, mucus and dead cells are deposited, which form the tonsil stones with a hard gritty center and a soft cheesy yellowish white covering. These tonsil stones are usually small and asymptomatic, but they may go on to become large yellow or grey stones producing various symptoms.
