Tongue scraper, toothbrush or toothbrush with built-in tongue scraper? “It’s a matter of personal preference,” says Dr Kuan. “The tool’s only as good as the skill of its user.” However, researchers at the University of Sao Paulo found a 75 per cent reduction in VSCs through the use of tongue scrapers, compared to only 45 per cent when a toothbrush was used. The American Dental Association recommends starting at the back of the tongue and working your way forward. Doing it the other way will just push the bacteria back into your mouth. Scrape gently seven to 10 times, and make sure to cover the entire tongue.
Improves Taste Sensation
Brushing too vigorously or with harsh bristles can damage taste buds and open the way for infection. Generally, though, tongue cleaning does not cause permanent harm to the tongue or taste buds, says Dr Kuan. In fact, a study published in the Journal of Clinical Periodontology found this actually improves taste sensation.
The most intense oral malodour usually happens when you wake up, after prolonged periods of reduced saliva flow, and not eating or drinking. Interestingly, the British Dental Association suggests eating rough foods also reduces tongue coating, and that eating a wholesome breakfast may often contribute to improvement.
