ABOUT THE SCIENCE
The science behind tongue scraping is simple. Using a tongue scraper regularly is linked to reducing back breath, dental decay and instances of gum disease.
REDUCE BAD BREATH
Although tongue scraping can’t replace brushing your teeth, scraping may do some things better. Researchers in a 2004 study found that scraping was 30% more effective at removing odor-causing bacteria than brushing. While scraping once isn't a long term fix, occasional scraping will help prevent long-term buildup that’s associated with severe bad breath.
Researchers in one 2005 study found that using a tongue scraper twice a day for seven days reduced the overall incidence of Mutans streptococci and Lactobacilli bacteria in the mouth. These bacteria types are known to cause bad breath and dental decay. Removing bacteria is key to preventing cavities, gum disease, and other conditions affecting the mouth.
Research suggests that using a tongue scraper twice daily can improve your sense of taste. By removing layers of bacteria and debris, your tongue may be able to better distinguish between bitter, sweet, salty, and sour sensations. By increasing your taste reception, not only do you eat less, but you also eliminate the need to add more sugar, salt, or strong spice to the food to make it more flavorful which, in excess, can lead to health issues.
