Tonsil Stones


What are tonsil stones?

Tonsil stones are small lumps of hard material that form in the tonsils. Tonsil stones can cause bad breath though they’re usually not painful or harmful. They’re also called tonsilliths.

You can usually treat tonsil stones at home. But in some cases, you may need surgery to remove the tonsils.

What are tonsils?

The tonsils are a pair of small, oval-shaped bits of tissue at the back of your throat. They have folds, gaps and crevices called tonsillar crypts.

Tonsils are part of your immune system, which helps protect against infection. Tonsils filter bacteria and viruses that enter your body through your mouth. Removing the tonsils does not affect your immune system.

What do tonsil stones look like?

Tonsil stones look like little white or yellow pebbles on your tonsils. You may have one tonsil stone or many tonsil stones. They’re usually small, though sometimes people can get large tonsil stones.

What’s the difference between tonsil stones and tonsillitis?

Tonsillitis is a tonsil infection. Both conditions can cause bad breath and throat pain. Usually, if you have tonsillitis, you’ll also get red, inflamed tonsils along with a sore throat, fever and headache.

Who’s at risk of tonsil stones?

People who have more tonsillar crypts tend to get more tonsil stones. These are also more commonly found in people who have had a lot of tonsil infections in their life. Tonsilliths tend to happen more often in teens.

How common are tonsil stones?

Tonsil stones are common. Many people get them and may not even know they have them.

Symptoms and Causes

What causes tonsil stones?

Materials and debris can get trapped in the tonsillar crypts. The material can harden or calcify, forming stones. Trapped material could include:

  • Minerals such as calcium.
  • Food or debris.
  • Bacteria or fungi.

What are the symptoms of tonsil stones?

Some tonsil stones don’t cause any symptoms. If you do have symptoms, they may include:

  • Bad breath (halitosis).
  • Cough.
  • Earache.
  • Sore throat.
  • Bad taste in your mouth.
  • Small white or yellow stones that you may spit up.

Other symptoms include:

  • Difficulty swallowing.
  • Feeling that something’s stuck in your throat.
  • Small white patches on your tonsils.
  • Throat infections that are hard to treat with antibiotics.

Diagnosis and Tests

How are tonsil stones diagnosed?

To diagnose tonsil stones, your provider may:

  • Do a physical exam, looking inside your mouth and throat.
  • Perform an imaging scan if they cannot see the stones easily.
  • Dislodge the stones using a dental pick.

Sometimes, a healthcare provider happens to notice tonsil stones during an exam. If you don’t have any symptoms, your provider might notice a stone during a scan or X-ray for a different problem. Or your dentist may see them during a dental exam.

Management and Treatment

How are tonsil stones treated?

Usually, treatment aims to manage tonsil stone symptoms. There isn’t a specific treatment method for stones. Make sure to:

  • Brush teeth regularly.
  • Gargle with warm salt water.

Can I remove the tonsil stones myself?

You can try these at-home methods to get rid of tonsil stones:

  • Gargling: Vigorous gargling using salt water has a few advantages. It helps your throat feel better, plus it can dislodge the tonsil stones. It may even get rid of the bad odor. This is particularly helpful when you gargle after eating to prevent food and debris from getting caught in the tonsil crypts.
  • Coughing: Some people find that a strong cough can loosen stones and bring them up.
  • Using an object: If gargling and coughing don’t dislodge the stones, it’s tempting to use your finger or a toothbrush to get rid of tonsil stones. But you can easily scratch your delicate tonsils. They can get infected. Instead, if you want to use an object, try a cotton swab.

Are medications used to treat tonsil stones?

Your healthcare provider will tell you if you need antibiotics to treat tonsil stones. In most cases, providers don’t use antibiotics. These medicines don’t treat the underlying cause of tonsil stones. But you may need antibiotics if you develop a bacterial infection.

Is there a way to remove tonsil stones surgically?

If tonsil stone symptoms are bothering you, talk to your provider. They may refer you to an ENT — an ear, nose and throat specialist. The ENT can discuss your surgical options with you.

Healthcare providers may recommend surgical tonsil stone removal if tonsil stones are:

  • Large.
  • Causing pain or other problems.
  • Causing recurrent tonsil infections or sore throats.

Will I need a tonsillectomy because of tonsil stones?

In some cases, healthcare providers recommend a tonsillectomy — having your tonsils removed. This procedure may help if tonsil stones keep coming back or if they are causing repeated infections.


How can I prevent tonsil stones?

You can take steps to prevent tonsil stones:

  • Brush and floss regularly. Make sure to brush the front and back of your tongue, too.
  • Quit smoking.
  • Gargle with salt water after eating.
  • Use a water pick to clean your mouth and help dislodge any tonsil stones.
  • Stay hydrated by drinking plenty of water.

Outlook / Prognosis

What’s the outlook for people with tonsil stones?

Tonsil stones are common. They rarely cause serious health problems. Many people have tonsil stones and don’t even know they have them. You can treat them at home. If tonsil stones keep coming back, you and your healthcare provider can discuss a more permanent solution.

A note from Cleveland Clinic

Tonsil stones are small lumps of hardened material that form on your tonsils, in the back of your throat. They usually don’t cause serious health problems. The main sign of tonsil stones is bad breath. You can usually try to get rid of tonsil stones using at-home methods, such as saltwater gargles. If home tonsil stone removal doesn’t work, or the stones keep coming back, talk to your provider. If the issue is recurring infections, you may need a tonsillectomy to remove your tonsils.
