Tonsilloliths (or tonsil stones) are small calcified deposits that form in the crypts of the tonsils, and represent one of the most frequently underestimated causes of persistent bad breath.
Why it happens: The tonsils have natural cavities where food debris, mucus, and dead cells can become trapped. Over time, bacteria break down this material, which hardens to form small white or yellowish deposits that release a strong sulfur odor—often significantly more intense than regular everyday bad breath.
How to tell if this is the cause: Signs include small white dots visible at the back of the throat, a persistent metallic or sour taste, the sensation of having something stuck in your throat, and breath that does not improve much with normal brushing or mouthwash.
The role of Frelopop: While frequent tonsilloliths may require dental or medical attention, a targeted oral spray helps manage bacteria and surface odor on a daily basis, keeping breath fresher between care routines.
