Those small white stones in your throat that cause bad breath are called Tonsil stones (also known as tonsilloliths).
They form in the crevices (crypts) of the Tonsils, which are located at the back of your throat.
What Are Tonsil Stones Made Of?
Tonsil stones are hardened deposits made from:
- Food particles
- Dead cells
- Mucus
- Bacteria
When this debris gets trapped in the tonsil crypts, bacteria break it down, producing sulfur compounds — which cause bad breath (halitosis).
Common Symptoms
- Persistent bad breath
- A feeling like something is stuck in your throat
- Visible white or yellow lumps on the tonsils
- Sore throat
- Difficulty swallowing (in larger stones)
- Ear pain (referred pain from throat nerves)
Some people don’t notice them until they cough one out.
Are They Dangerous?
Tonsil stones are usually harmless. However, frequent or large stones can cause discomfort and chronic bad breath.
How to Get Rid of Them
Mild cases:
- Gargle with warm salt water
- Maintain good oral hygiene (including tongue cleaning)
- Stay hydrated
Persistent or large stones:
- A healthcare provider may remove them
- In severe recurring cases, tonsil removal (tonsillectomy) may be considered
When to See a Doctor
Seek medical care if you have:
- Severe pain
- Difficulty swallowing or breathing
- Frequent infections
- Very large or persistent stones
