Clean your breath with this stainless steel tongue cleaning kit! Your brain is constantly detoxing through your gums, and as these toxins enter the mouth they cause tooth decay, since many of the volatile toxins (heavy metals for instance) will strongly pull calcium from teeth, if the salivary calcium is not enough. When the toxins are fully neutralized by calcium, they end up on the tongue as residue. Naturally, you want this away from your body! Try to gently clean - it's preferable not to have micro-abrasions on your tongue as that makes your mouth leak directly into the bloodstream - just like flossing.
