A team of researchers from the University of Groningen in the Netherlands found that chewing of gum trapped bacteria. They expected that regular use of chewing gum can help lower bacterial load in oral cavity.
“Assuming a volume of saliva of around 1ml in the oral cavity, our results indicate that chewing of one piece of gum removes around 10% of the oral microbial load in saliva,” the authors wrote.
Scanning-electron-microscopy was used to view the bacteria trapped inside the gums. Different methods were used to calculate the total number of bacteria trapped in the gums.
They found that the total number of bacteria thus trapped increased with an increase in the chewing time.
Researchers said that chewing gum can also help maintain oral health as brushing or flossing.
“Chewing however, does not necessarily remove bacteria from the same sites of the dentition as does brushing or flossing, therefore its results may be noticeable on a more long-term than those of brushing or flossing,” they wrote.
According to the American Dental Association, chewing gum after meal can help remove acids responsible for tooth decay.
