Many people have experienced an odd sensation in the back of their throat—a tickling feeling, mild irritation, or the sense that something is stuck. In some cases, after coughing, sneezing, or clearing the throat, a small white or yellowish lump suddenly appears.
For those seeing it for the first time, the experience can be alarming. Some worry it may be a sign of infection or a serious medical problem. Fortunately, in many cases, the mysterious object is something known as a tonsil stone, also called a tonsillolith.
While they are usually harmless, tonsil stones are surprisingly common and can sometimes cause unpleasant symptoms.
What Exactly Are Tonsil Stones?
Tonsils contain tiny pockets and crevices known as crypts. Over time, food particles, dead cells, mucus, and bacteria can become trapped inside these small openings.
As the material accumulates, it may harden and form small white or yellow deposits. These hardened masses are what doctors refer to as tonsil stones.
