To evaluate your own breath, you can use the licked-wrist test (smell your wrist after waiting a few seconds); if your breath is strong, regular tongue cleaning helps restore freshness, though this does not replace a professional check-up.

The licked-wrist test is a classic self-assessment method documented in research (such as the review by Bollen and Beikler, 2012) to estimate saliva odor. However, this test remains highly subjective and can be imprecise because it primarily evaluates the front of the tongue, whereas odor-causing deposits are mostly located at the very back of the mouth. Regarding tongue cleaning, the scientific evidence is well established: a Cochrane systematic review (by Outhouse et al., 2006) demonstrates that the use of a tongue scraper is particularly effective for temporarily reducing oral odors. Furthermore, another systematic review from the University of Groningen confirms this daily benefit, while noting that mechanical brushing alone does not always resolve discomfort in the long term. The creator's advice to consult a professional for a complete assessment is therefore very sound, as strong breath can also be linked to other factors such as dry mouth or the balance of digestive flora.
