[HIGHLIGHTS] The simple accessory (that most of you don't know) that a third of Americans use to prevent tooth decay - voila! health

About a third of Americans do not start the day without brushing their teeth and cleaning their tongue. The oral cavity contains over 700 species of bacteria, making it the second largest and most diverse microbiome in the human body after the gut.

Overgrowth of certain types of bacteria can lead to a number of negative consequences, from gum disease to halitosis, aka bad breath. The best way to reduce the amount of bacteria in your mouth is to clean your tongue twice a day after brushing your teeth.
