Tonsil stones are not contagious to others. Tonsil stones are actually precipitated crystals of calcium carbonate salts, most of which are located in the parenchyma of the tonsils and a few on the surface of the tonsils. Since they are precipitated calcium compounds and are not pathogenic microorganisms, there is no contagion.
Tonsil stones are formed when tonsil secretions increase and the tonsil crypts are blocked, resulting in the long-term accumulation and calcification of decaying food debris, shedding epithelium, bacterial colonies, and other foreign matter deep in the crypts to form tiny, white, hard particles. Essentially tonsil stones can be called calcium carbonate belongs to the inorganic material, does not belong to the pathogenic microorganisms, so it is not infectious.
When the size of the stone increases to a certain extent, the patient will cough it out when coughing, there is a strong odor, can cause the patient bad breath, can lead to swallowing difficulties, difficulty in opening the mouth, earache, sore throat and other symptoms. Smaller stones can be removed with a curette or forceps. Individual stones can be removed by suction with a negative pressure device. Large stones need to be removed by incision of the mucosa under surface anesthesia.
