Tongue cleansing has been medically shown to improve both oral care and wider health issues.
The oral care benefits:
Our tongues are almost a third of the surface area of our mouth. They are a rich surface of papillae that has been likened to a deep-pile carpet. That makes them an excellent trap for decaying food debris and bacteria.
Medical evidence shows that this cocktail will:
- Create bad breath, plaque and dental decay.
- Whilst clogging the tongue’s surface will reduce our taste sensitivity.
The benefits of tongue cleansing are thus:
It reduces bad breath
“Tongue bacteria accounts for 80% to 90% of all cases of bad breath”

“Cleaning the tongue after eating smelly, sticky, or greasy foods should be a routine oral hygiene activity, just as necessary as using deodorant or taking a shower"

It reduces plaque formation
“Plaque forming Streptococci counts increased tenfold after a week of not brushing the tongue"

It reduces tooth decay

It refreshes the palate - enabling our taste buds to function more effectively
“A dirty mouth cannot taste the subtle flavours in good food”

“Tongue cleaning, especially with the scraper, improves taste sensation, (there were) significant improvements for quinine and sodium chloride"

The wider health issues:
A good oral hygiene regime is actively recommended – including cleansing the tongue (since it represents one third of the mouths surface area), because:
"It reduces unfriendly bacteria entering the stomach and blood stream"

"It reduces the threat of heart disease - because of the link between poor oral care, periodontal disease and the consequential increased risk of cardiovascular disease"

"The presence of periodontal disease has been related to diabetes, coronary artery disease, and stroke. The tongue provides a major source of organisms for these local diseases and may potentially have overall systemic effects"

And specifically tongue scraping could be a far safer option than using mouthwashes with antiseptic
"Poor oral hygiene, the use of antiseptic mouthwash or antibiotics can kill commensal bacteria and disrupt nitric oxide production putting patients at risk for CVD" (cardiovascular disease)

"It reduces STDs residing on the tongue and the risk of HPV infection"
