Tonsil stones are a manifestation of chronic tonsillitis, and when patients develop tonsil stones, they need to go to a regular hospital to have them cleaned under the operation of a doctor. Tonsil stones are caused by repeated episodes of tonsillitis, which leads to the fibrosis of the crypts, the shedding of epithelium and bacterial debris formed by the caseous material accumulated in the crypts. When the stone is small, the patient may have no obvious feeling, as the stone increases in size, the patient may have a foreign body sensation in the pharynx, sore throat, itchy pharynx, cough, bad breath and other manifestations. For smaller stones, they can be removed by doctor’s operation using spatula or pliers, and some can be removed by negative pressure suction; for stubborn tonsil stones or larger stones, tonsillectomy or incision and extraction of stones can be considered for cleaning. Usually do not recommend patients to clean themselves, so as not to damage the mucosa of the throat, patients usually pay attention to drink more water, develop good oral hygiene habits, morning and evening brushing, gargling after meals, to keep the oral cavity clean and so on.
