Have you ever coughed up a small white lump from the back of your throat and been caught off guard by its strong smell? It can feel surprising, even a little concerning. The good news is that you are not alone, and in most cases, it is not a serious health issue.
These formations are known as tonsil stones, and while they are common, there are simple ways to reduce how often they appear.
What Are Tonsil Stones?
Tonsil stones, also called tonsilloliths, are small deposits that form in the crevices of your tonsils. The tonsils sit at the back of your throat and help your body defend against infections.
Over time, tiny particles such as food debris, dead cells, mucus, and bacteria can become trapped in small pockets on the surface of the tonsils. As this material builds up, it can harden into small, whitish lumps.
Their size can vary. Some are barely noticeable, while others may grow to several millimeters.
Certain people are more prone to developing tonsil stones, especially those with deeper or more irregular tonsil folds where debris can collect more easily.
