Tonsil stones (tonsilloliths) are hard deposits formed from trapped food, bacteria, and minerals on your tonsils. They often cause bad breath and mild throat discomfort.
Symptoms include sore throat, trouble swallowing, swollen tonsils, ear pain, persistent cough, and a metallic taste in the mouth.
Treatment options are self-removal with a cotton swab, gargling salt water, using oral irrigators, or coughing. In severe cases, surgery may be needed.
Prevent tonsil stones by maintaining good oral hygiene, gargling salt water, and brushing your tongue. If symptoms persist, consult a doctor.
