The main causes of white particles on the sides of the throat are chronic tonsillitis, tonsil stones and tonsil keratosis. 1. Chronic tonsillitis: in chronic crypt tonsillitis, a large number of shed epithelial cells, lymphocytes, leukocytes and bacteria gather in the gland crypts to form pus plugs, or crypt mouths due to inflammation scarring adhesion, the contents can not be discharged, forming pus plugs or cysts, which become the foci of infection. It looks like white particles on both sides of the throat. 2. Tonsil stones: Tonsil stones are white keratinized material composed of bacteria, metabolites and food debris, usually found inside the tonsil crypts, therefore, white particles on both sides of the throat may be tonsil stones. 3. Tonsillar keratosis: when the tonsil infection stimulates the overgrowth of epithelial cells, the lymphatic tissues in the tonsils will be abnormally keratinized, and milky-white, splinter-like keratinized material can be seen on both sides of the throat. There are white particles on both sides of the throat, you can actively go to the regular hospital to identify the cause of the disease, a clear diagnosis.
