What are tonsil stones?

The

tonsils

are

lymph nodes

located at the back of the throat.

Tonsil stones

(also called tonsilloliths or tonsil calculi) are small clusters of calcifications or stones that form in the craters (crypts) of the

tonsils

. Tonsil stones are hard and appear as white or yellowish formations on the

tonsils

. They usually smell bad (and make your breath smell bad) due to bacteria.

What are causes and risk factors of tonsil stones?

Several factors can cause or contribute to the formation of tonsil stones, such as the following:

  • Substances such as food, dead cells,

    mucus

    , and bacteria may get stuck in the nooks and crannies of the

    tonsils

    .
  • The body’s immune system, which sees these as foreign invaders, sends white blood cells to the area to fight infection. When the white blood cells are done, they leave small calcifications behind.
  • Usually, these small stones are swallowed but sometimes they get stuck in the tonsillar crypts and continue to grow into tonsil stones. Small stones are common; large stones are rare.

Risk factors for developing tonsil stones include people with:

  • Chronic or recurring

    tonsillitis

    (inflammation of the tonsils)
  • Large tonsils
  • Chronic sinus problems
  • Poor

    dental hygiene

  • Certain medications that make your mouth dry

What are the symptoms of tonsil stones?

In many cases, tonsil stones do not cause any symptoms. When symptoms do occur, they may include:

  • Persistent

    bad breath

    (

    halitosis

    )
  • White or yellow formations on the tonsil
  • Sore throat

  • Difficulty swallowing

  • Ear

    pain

  • Swollen tonsils

  • The sensation of a foreign object lodged in the back of the throat/choking feeling
  • Cough

  • Chronic tonsil inflammation/infection

What specialists diagnose and treat tonsil stones?

If symptoms of tonsil stones are severe, you may see an ear, nose, and throat (ENT) specialist, also called an otolaryngologist.

How are tonsil stones diagnosed?

Tonsil stones can frequently be seen in the back of the throat. They typically appear as white or yellowish spots on or around the tonsils that may range in size from a grain of rice to a pea.

For stones that cannot be visualized, an

MRI

or

CT scan

can help make a definitive diagnosis.

What are the treatments for tonsil stones?

Tonsil stone treatment is not always needed. Stones frequently either dissolve on their own or are coughed up.

For stones that do not go away on their own, there are several types of treatments:

  • Medications:
    • Antibiotics to help reduce bacteria
    • Antihistamines

      to reduce mucus from sinus problems or

      allergies

  • Laser treatment (laser tonsil cryptolysis): a noninvasive treatment that helps minimize or remove the tonsil pockets (crypts) where the tonsil stones are lodged
  • Coblation cryptolysis: radio waves are used to change a salt solution into charged ions that can cut through the tissue to reduce crypts on the tonsils and eliminate tonsil stones
  • Tonsillectomy

    :
    removal of the tonsils, usually the last resort but the only way to eliminate tonsil stones and prevent new ones from forming

How do you get rid of tonsil stones at home?

Manual tonsil stone removal at home is generally not recommended. Tonsils are delicate tissues, and removing them on your own may cause bleeding and infection.

Home remedies to get rid of tonsil stones include:

  • Salt-water gargle: This may help dislodge tonsil stones and get rid of the odor and

    bad breath

    they cause.
  • Coughing

    :
    Tonsil stones are often coughed up inadvertently. In some cases, a hard

    cough

    may help dislodge them.
  • Oral irrigation: Oral irrigators can sometimes be used to gently shoot water into the back of the mouth in an attempt to dislodge the tonsil stones. Follow instructions and use caution because it is possible to injure the tonsils if it is not done gently.

How long do tonsil stones last?

The length of time tonsil stones last varies and depends on several factors.

  • Tonsil stones may dislodge or dissolve on their own in a short time.
  • Tonsil stones may last for weeks if bacteria continue to grow on the tonsils due to tonsil stones deep in the throat.
  • If tonsil stones are ignored and left in place without lifestyle changes, they may last for years.
  • The only surefire way to cure tonsil stones and prevent any recurrence is to have the tonsils removed (

    tonsillectomy

    ).

How to prevent tonsil stones

There are several ways to prevent tonsil stones, such as the following:

  • Maintain good oral hygiene: Brush and floss regularly; consider using a tongue scraper to remove bacteria.
  • Gargle regularly with mouthwash or saltwater solution.
  • Drink plenty of water.
  • Quit smoking

    .
  • Avoid excess

    alcohol

    .
  • Reduce consumption of carbonated

    beverages

    such as sodas.
  • Treat

    sinus infections

    or

    allergy symptoms

    promptly.
  • Limit dairy products.
