Removing tonsil stones (small whitish deposits in the tonsils) helps eliminate bad breath and restore a fresh mouth.

The accumulation of debris and bacteria forming these small clusters in the folds of the throat is indeed a well-documented cause of olfactory discomfort due to the odorous compounds they release. A systematic review published in Otolaryngology–Head and Neck Surgery confirms this direct link, while clarifying that these deposits actually account for only about 3% of overall bad breath cases. For the vast majority of people, the primary cause lies instead on the surface of the tongue or between the gums. Regarding removal, a randomized clinical trial (RCT) demonstrated the effectiveness of targeted mouthwashes or simple salt water gargles to reduce these clusters gently. Finally, expert consensus (expert opinion) emphasizes that aggressive manual extraction with sharp or rigid objects must be strictly avoided to prevent injury to sensitive tissues. The creator's advice is therefore valid for the individuals concerned, although its importance is often overestimated compared to standard oral hygiene.
