The granular couscous-like secretion or white wheat skin-like secretion that is repeatedly coughed up is not necessarily a tonsil stone, but may be caused by the repeated discharge of pus plugs from the tonsils. Because there are 6-20 crypt foci inside the tonsils, when acute infection occurs, the crypt foci can be concentrated by white blood cells and bacteria into pus plugs. In the interval, the pus plugs inside the tonsils will be discharged gradually with the squeezing of swallowing action, which will cause a series of symptoms. At this time, it is best to pay attention to oral hygiene, such as brushing teeth after meals and before bedtime, and rinsing the mouth with mouthwash. You can also try tonsil massage to promote the discharge of pus, but the long-term effect is not particularly good. The most curative method is to remove the tonsils, especially if there are recurrent tonsillitis attacks.
