1. What are "臭い玉"? Their Formal Name and True Nature

Commonly referred to as "臭い玉," these objects are formally known as "tonsil stones" or "tonsilloliths." They form when bacteria and waste accumulate in the crevices of the tonsils at the back of the throat and become calcified.


  • Appearance: Small, white to yellowish granules with a cheese-like texture

  • Odor: Strong sulfuric or putrid smell

  • Location: Primarily in the crypts of the palatine tonsils


2. Causes and Mechanism of "臭い玉" Formation

The following factors are involved in a complex manner.


  • Stagnation of food particles and mucus

  • Bacterial growth (such as anaerobic bacteria)

  • Accumulation of white blood cells and keratin

  • Dryness due to mouth breathing or dry mouth


Tonsil stones are particularly likely to form as a result of immune responses, making them more common after infections.


3. Characteristics of People Prone to Tonsil Stones

  • Frequent mouth breathing (during sleep or due to nasal congestion)

  • Large tonsils with deep crevices

  • Chronic tonsillitis or allergic constitution

  • Low saliva production (due to stress or aging)

  • Inadequate brushing or thick tongue coating


4. Self-Check Methods for Tonsil Stones

  • Open your mouth wide in a bright place and observe the back of your throat with a mirror

  • Check for white or yellow particles on the tonsils

  • Abnormal values may appear on a breath checker

5. Is It Okay to Remove Them Yourself? Points to Consider

  • Gently push them out with a cotton swab or ear pick

  • Pushing too hard can cause bleeding or inflammation

  • Oral irrigators (water picks) are also effective

  • Maintaining cleanliness of hands and tools is essential for infection prevention


6. Medical Treatment Options and When to Consult

  • Suction or cleaning procedures at an ENT clinic

  • Tonsillectomy may be considered if chronic inflammation is severe

  • Consult a doctor if occurrences are frequent or if bad breath is strong


7. Risks of Tonsil Stones: Is It Okay to Leave Them Alone?

  • Basically benign and not life-threatening

  • However, unpleasant symptoms such as bad breath, inflammation, and pain may occur

  • Be cautious if accompanied by a strong throat discomfort or fever


8. Methods to Prevent Smelly Stones: Oral Environment and Lifestyle

  • Frequent gargling (with iodine or saline solution, etc.)

  • Oral cleaning with tongue brushing and dental floss

  • Focus on nasal breathing (treatment for rhinitis)

  • Ensure adequate hydration (promote saliva secretion)


9. Reactions on Social Media and "Common" Symptoms

  • "I thought there was something stuck in my throat, and it turned out to be a smelly stone"

  • "The moment it popped out, it smelled terrible"

  • "The satisfaction when it comes out is addictive"

  • Videos on how to remove them are trending on TikTok and YouTube
