One of the most common symptoms is a persistent sensation that something is lodged in the throat, leading people to repeatedly swallow, cough, or clear their throat. Tonsil stones may also contribute to bad breath because bacteria can produce unpleasant-smelling sulfur compounds. Other possible symptoms include throat irritation, difficulty swallowing, ear discomfort, or visible white or yellow spots on the tonsils.
Tonsil stones are generally harmless and may eventually dislodge on their own, particularly while coughing, brushing the teeth, or gargling. However, similar-looking spots and throat symptoms can sometimes have other causes, including tonsillitis, oral thrush, or viral infections. Those conditions may be accompanied by additional symptoms such as fever, fatigue, significant throat pain, or swollen lymph nodes.
If the problem keeps returning, becomes painful, worsens, or occurs alongside fever or other concerning symptoms, medical evaluation is recommended. A healthcare professional can examine the throat, determine whether tonsil stones are responsible, and rule out infection or another underlying condition. Persistent difficulty swallowing or breathing requires prompt medical attention.
