Japanese researchers found that the high concentration of acetaldehyde in people with more tongue fur is higher, and acetaldehyde is considered to be a substance that can cause oral and laryngopharyngeal cancer, so clearing the tongue coating is helpful to prevent these cancers. The
research team said in a report that the tongue coating is a layer of white moss that exists on the tongue surface, which is made up of food residue, mucous cells from the mouth and bacteria, and so on. When dry mouth is easy to appear tongue coating, but also cause halitosis.
they investigated 65 healthy men and women, and found that the tongue coating covered more than 2/3 of the surface of the tongue, and the concentration of acetaldehyde in the exhalation of the former was about 3 times compared to those who covered less than 1/3 of the tongue surface.
study also found that after cleaning the tongue, the concentration of acetaldehyde in the breath decreased. The team believes that acetaldehyde is a carcinogen in oral and throat cancers, so keeping the tongue clean will help prevent these cancers.
the research team is going to study the relationship between tongue coating and cancer in detail and investigate which bacteria are associated with cancer.
