While kombucha sales now account for 10% of all refreshment beverage sales, according to the Fermentation Association, kombucha isn’t actually all that new. This fermented tea drink was first made in China sometime around 220 B.C. The drink made a comeback among health aficionados and internet influencers in recent years, with kombucha sales increasing 21% to $729 million in 2018.

Whether you make your own kombucha or buy it at the store, kombucha has several potential health benefits. Live kombucha provides your body with probiotics, the healthy gut bacteria that can aid digestion and reduce inflammation, especially after a course of antibiotics. Kombucha, like the tea it’s made of, is also rich in antioxidants, which can help protect your body against disease. Research shows the teas often found in kombucha may reduce the risk of heart disease, protect against cancer and can help manage Type 2 diabetes.

Despite its benefits, kombucha contains high amounts of acid and is usually flavored with sugar or sugar-heavy fruit juices as a result. This combination can attack and erode your tooth enamel to expose the dentin, or inner layer of your teeth. A lack of enamel causes teeth to become more susceptible to decay and more sensitive to certain hot, cold, sweet or spicy foods. It can also cause your teeth to yellow over time.
