Tonsil stones accidentally swallowed do not require special treatment. Tonsil stones are usually located at the crypt orifice of the tonsils, or in the parenchyma of the tonsil lymphoid follicles. Stones at the fossa are formed by long-term sedimentation and mechanization of glandular secretions and food debris. Stones in the tonsil parenchyma are formed slowly by the calcification of calcium carbonate salts. The size of the stone varies, the shape is oval, the diameter is about 1-10mm, most of them will not be more than 3mm. tonsil stone itself is not harmful to health, so if tonsil stone is swallowed accidentally, it will be excreted through the normal excretion of the intestinal tract, and it will not cause any harm to the body, and there is no need for treatment.
