What are tonsil stones?
The tonsils are small oval-shaped bits of tissue at the back of the throat and are part of your immune system. They help protect you from infections by filtering bacteria and viruses that enter the body through the mouth. Tonsil stones are little hard lumps that develop in the tonsils and can produce bad breath.⁵ They are generally painless and harmless and are also referred to as tonsillitis. Tonsil stones are usually small and can look like yellow or white pebbles. In most cases, you can treat tonsil stones at home, but they may need a surgical procedure to remove the tonsils in some cases, especially if tonsil stones keep reappearing.¹
What causes tonsil stones?
Tonsil stones can result from food particles, mucus, dead cells, and bacteria trapped in small pockets on your tonsils due to improper oral hygiene. When this debris builds up and then hardens or calcifies, tonsil stones can start to form and cause soreness or swelling. Such complications happen mainly to those who have long-term tonsils inflammation (chronic tonsillitis) and get tonsillitis more often than normal. Other potential causes include poor dental hygiene, having large tonsils and chronic sinus issues.²
Symptoms of tonsillitis
People often confuse tonsillitis with having a cold or severe flu that causes tonsils inflammation. Here are some of the main symptoms of tonsillitis in children and adults:³
- Having a sore throat.
- Facing difficulty swallowing.
- Coughing and headache.
- Exhaustion and tiredness.
- High temperature above 38C.
- Bad breath.
- White pus-filled spots on the tonsils.
- Painful swollen glands.
While tonsil stones are not contagious, it is usually the result of an infection that is contagious; like a cold or flu. Hence, it is recommended to follow standard hygienic practices to stop infections from spreading when you feel any of the symptoms mentioned above.³
Tonsil stones treatment
Even though tonsil stones can be harmless, they can cause discomfort, bad breath, and other irritations in many cases. Also, large tonsil stones can damage normal tonsil tissue, leading to severe swelling, inflammation and infection. Here are some of the ways one can deal with tonsil stones or remove tonsil stones if necessary:¹

- Tonsil stones surgical removal is another treatment method if symptoms are too disturbing. Your GP may refer you to an ENT, an ear, nose and throat specialist to discuss the surgical options available depending on your case. Tonsil stone removal is recommended in cases like large tonsil stones, severe pain and recurrent sore throats or tonsil infections.
- Tonsillectomy means having your tonsils removed completely, and it is necessary if tonsil stones keep coming back and are causing repeated infections. Note that removing the tonsils does not affect your immune system.
- Cryptolysis is a procedure in which medical professionals use a laser or a radiofrequency wand to scar your tonsils and reduce potential tonsil stones.

A large tonsil stone is considered a complication that needs immediate attention.
