Overview

Your tonsils are areas of tissue in the back of your throat. They are part of the immune system, which helps your body fight infection. Tonsil tissue has small gaps in it. Tonsil stones form when bacteria and debris get stuck in those gaps and harden.

Tonsil stones look like white or yellow pebbles on your tonsils. They can cause bad breath, a sore throat, a bad taste in your mouth, and ear pain. Or they may not cause any symptoms.

Usually, tonsil stones can be treated at home. But large stones that cause pain or other problems may have to be removed by a doctor. And if your tonsil stones keep coming back or are bothering you a lot, your doctor may recommend removing your tonsils.

How can you care for yourself at home?

• Gargle with warm salt water. This helps reduce swelling and discomfort. It might also help remove the stones. Gargle with 1 teaspoon (5 mL) of salt mixed in 1 cup (250 mL) of warm water.
• Use something soft to gently remove tonsil stones that bother you. Some people use the end of a cotton swab.
• Practice good oral hygiene. Brush and floss your teeth regularly.
