In a nutshell

Tonsil stones are small, pale deposits in the hollows of the palatine tonsils. They often go unnoticed but can cause bad breath or a foreign-body sensation.

Why does it happen?

Cell debris, food particles, and microorganisms collect in tonsillar crypts. The material can mineralize and become firmer. Bacterial breakdown products contribute to the odor; a stone does not automatically mean acute tonsillitis.

Frequency

Tonsil stones are found in some people and may go unnoticed. A reliable general prevalence depends on the examination method and minimum size, so none is given here.

Frequency is a qualitative description, not your individual probability.

Is it normal?

Small stones without symptoms are usually harmless.

When to seek advice

Fever, severe one-sided throat pain, difficulty opening the jaw, or swallowing problems should be medically assessed; seek immediate help for difficulty breathing. Do not use sharp tools on the tonsils.
