The chewing gum will spit about 10 minutes after chewing

Recently, a new study published in the "Science Public Library Comprehensive Volume" found that a piece of chewing gum can eliminate 100 million bacteria in the mouth, accounting for about 10% of the total number of bacteria in saliva.

The study was conducted by researchers at the University of Groningen in the Netherlands. They used two unknown chewing gums to chew the volunteers and then tested chewing gum. The results showed that chewing gum chewed for 10 minutes and absorbed about 100 million bacteria. The researchers said that chewing gum can effectively play a role in cleaning the oral cavity, but chewing gum also has phlegm:

The 30 seconds before chewing gum is the strongest. The study found that after 30 seconds, the chewing gum's ability to adsorb bacteria gradually decreased, and its clean mouth function began to deteriorate.

Sugary chewing gum can be counterproductive. Chewing sugar-free chewing gum can effectively remove oral bacteria, and sugary chewing gum will nourish bacteria and help people become ill.

The time for chewing gum should not exceed 10 minutes. Too long chewing gum will change its structure, the hardness of the glue will decrease, affect the adhesion of glue to bacteria, and cause the adsorbed bacteria to be released back into the mouth. Chewing for a long time can also cause the mouth to dry out, which is conducive to bacterial growth. It is recommended that the chewing gum should be taken within 10 minutes and no more than 15 minutes at a time.
