How do you feel about this?

A Reddit user woke up to an unsettling surprise—a huge tonsil stone rolling around their mouth. They shared a photo with a coin for scale, calling it a “boulder” that mysteriously appeared overnight.

Tonsil stones (tonsilloliths) form when food, mucus, and debris get trapped in the tonsils and harden. While often harmless, they can cause bad breath, sore throat, and difficulty swallowing.

Other Redditors chimed in—some joking about fresher breath, others warning there could be more hidden deeper inside. People with larger tonsils or a history of tonsillitis are more prone to getting them.

One commenter said they were glad they’d had their tonsils removed, calling it a painful but worthwhile procedure.

Though not dangerous, this viral post reminded us just how weird and uncomfortable minor health issues can be—especially when they show up uninvited!
