black tea theaflavins and green tea are good for oral health, preventing gingivitis, periodontal disease and cavities

Stay calm and stop (dental) carrying on! Tea time can stop dental caries, or cavities. Though it’s not usually thought of as being good for your teeth, emerging research is proving tea to be a veritable dentist.

Theaflavins are polyphenolic flavonoid antioxidants found in black tea. You might also want to find them in your toothpaste from now on. When healthy adults brushed their teeth with toothpaste with or without added theaflavins, saliva samples showed that the toothpaste with theaflavins significantly increased bacteria associated with oral health and significantly decreased harmful oral pathogens.

The new study found that adding theaflavins from tea to toothpaste could produce a toothpaste that is “a promising oral care product.”

Earlier studies have also shown that black tea polyphenols are good for your teeth. Those studies found that drinking black tea inhibits the growth of bacteria that causes cavities. It also prevents that bacteria from adhering to your teeth. As in the new study, it was the polyphenols that were doing the work. The people in one study rinsed with the tea for 30 seconds every 3 minutes, 5 times (American Society for Microbiology, May 24, 2001). In another they rinsed for 1 minute 10 times a day.

Not to be outdone, there are a plethora of studies showing that the very healthy green tea is also good for your teeth. Green tea and its flavonoids prevent gingivitis, periodontal disease, tooth loss, plaque and cavities.

So, enjoy tea time, stay calm and don’t caries on!
