Tonsil stones are usually formed due to irritation such as food debris left in the tonsil crypts or inflammation of the tonsils. The hole after a tonsil stone falls out is actually the tonsil crypt. Tonsil stones do not usually disappear, but the hole may gradually shrink.
Tonsil crypts belong to the normal structure of the tonsils, the epithelial tissue on the surface of the tonsils into the gland and the formation of the normal structure, under normal circumstances, the surface of the tonsils seem to be very smooth, flat, but in fact the tonsils are divided into a lot of crypts, each crypts are closely adjacent to each other, due to the opening of the crypts are in the state of closure, the regular state of the naked eye is not easy to observe.
So after the tonsil stones fall, the hole above the tonsil is just the expansion of the crypts, which itself will not disappear, it is possible that with the elasticity of the tonsil tissue itself will gradually shrink. Usually need to pay attention to more gargling, keep oral hygiene, prevent recurrence of tonsil stones.
