Bubble gum or science?
Advance notice to the Editorial board:
At the beginning of the article it is honestly written "This work was funded by Wm. Wrigley Jr. Co, Chicago, USA, and SASA BV, Thesinge, NL". The first organization does not need to be represented, and the second is a Dutch private laboratory, whose employees conducted an epoch–making study on five volunteers (usually in such cases they put experiments on themselves). With the use of a toothbrush (even without paste), the results were not compared. And for how long the population of microbes recovered the lost 10%, the article does not indicate, but the average bacterium under favorable conditions divides every half hour. But the article has been published, and now the manufacturer of chewing gum can claim on a blue eye:
The effectiveness of chewing gum has been proven
in the fight against pathogenic bacteria
A single piece of gum catches 100 million bacteria (ten percent of the average number of microorganisms in saliva) in ten minutes. The study (Wessel et al., Quantification and Qualification of Bacteria Trapped in Chewed Gum) is presented in the journal PLoS One, and the Daily Mail briefly reports about it: Is GUM better than flossing? 10 minutes of chewing can remove 100 MILLION bacteria from your mouth, study claims.
In one experiment, a limited amount of bacteria was injected into the oral cavity of volunteers, after which people were asked to chew gum for ten minutes. It turned out that there were about 100 million bacteria on each plate. "The trapped bacteria were visible in the images obtained by a scanning electron microscope," the article reports. However, only chewing gum without sugar brings benefits: sweet substances only feed the microbes that live in the oral cavity and on the teeth.
Chewing gum is most effective in the first 30 seconds of use – then the bacteria are caught worse and worse. Moreover, with incessant chewing, some of the microorganisms return to the oral cavity.
Based on the study, scientists hope to develop a chewing gum that acts selectively and removes certain types of pathogenic bacteria from the mouth.
