A white object in the throat may be caused by purulent tonsillitis, tonsil cysts, tonsil stones and other factors. 1. Purulent tonsillitis: mainly caused by bacterial infection, purulent inflammation, may appear severe sore throat, enlarged tonsils, white pus spots and other symptoms. 2. Tonsil cyst: it usually occurs on the surface of the tonsil at the mouth of the crypt, mainly because of pharyngeal infection, repeated inflammatory stimulation and other factors leading to glandular secretion blockage, thus forming a cyst, which may appear on the tonsil as a small yellowish-white swelling. 3. Tonsil stones: mostly occur in the tonsil crypt, mainly because of the formation of calcium salt deposition, usually manifested as yellowish-white, can appear throat discomfort, bad breath and other symptoms. If you find white objects in your throat, it is recommended that you consult a hospital for a clear diagnosis and treatment.
