Researchers of Netherlands University of Groningen found out that chewing gum traps the bacteria in the mouth and when gum is spitted out, bacteria along with the gums goes out.

As part of the study, researchers asked five biomedical engineering students to chew two types of chewing gums for different period of time, from 30 seconds to 10 minutes.

After the given time, they were asked to spit the gum in sterile water for analysis. The gum had about 100 million bacteria and researchers were shocked to see this. Also, they analysed that the more time we chew the gum, the more bacteria gets trapped to the gum.
