More Tea, Less Cavities

Red, swollen gums that bleed easily are the first signs of gum disease. Periodontal diseases, including gingivitis and periodontitis, are serious infections that can lead to tooth loss if left untreated. A new study reveals drinking black tea can help prevent gum disease and fight cavities.

In several trials, volunteers rinsed their months with black tea. Rinsing for 1 minute, 10 times a day resulted in a decrease in plaque build-up but only multiple rinsing with the tea prevented bacteria growth. More than 300 types of bacteria make up dental plaque. The bacteria produce acid that causes cavities on the surface of the teeth. Gum disease begins when the bacteria in plaque causes the gums to become inflamed. Researchers say when exposed to black tea, certain bacteria lose their ability to produce acid.

The chemicals in black tea, called polyphenols, suppress the growth of cavity-causing bacteria in plaque and reduce acid production levels. People can incorporate tea into their daily eating schedule. If sequenced properly between meals and normal hygiene, drinking black tea could reduce the number of cavities and prevent periodontal disease.

Black tea is the most popular beverage all over the world. It is derived from the dried leaves of the Camellia plant.
