Tonsil stones—also known as tonsilloliths—are small, white or yellowish formations that develop in the crevices of the tonsils. They form when food particles, mucus, and bacteria get trapped and harden over time. Although tonsil stones are usually harmless, they can be uncomfortable and cause persistent bad breath.
This guide explains what causes them, how to identify them, and which natural home remedies may offer relief.
What Are Tonsil Stones?
Tonsil stones are calcified debris that build up in the small pockets (crypts) of the tonsils. They range from tiny grains to larger, visible lumps that may cause discomfort.
They are not a disease, but rather a common condition for people with deep tonsil crevices or repeated throat infections.
Causes of Tonsil Stones
- Trapped debris (food particles, dead cells, mucus) in tonsil crypts
-
- Chronic sinus congestion causing mucus drainage
- Poor oral hygiene
- Recurrent tonsillitis
- Large or deeply pitted tonsils
- Dry mouth, which allows bacteria to multiply faster
These factors lead to buildup, which eventually hardens into small stones.
