Green Tea’s Contribution To Healthy Teeth and Gums

Previous research has shown that green tea has the ability to reduce inflammation and periodontal bacteria in the mouth. This may be due to the presence of the antioxidants found in green tea. By hindering the body’s response to inflammation, green tea helps to promote periodontal health and reduce the risk of other oral problems, such as:

Bad Breath

Green tea is proven to kill the microbes that causes bad odour in the mouth. A study done by the University of British Columbia’s Faculty of Dentistry found that green tea outperforms breath mints and chewing gum, when they measured the level of odour components in people’s mouth after they were given green tea, mints, and gum to help with bad breath.


Green tea is able to prevent cavities by controlling bacteria and lowering the acidity of saliva and dental plaque. A recent Egypt-based study found that after people rinsed their mouths with green tea, they has less bacteria and acid in their mouths. The study also found that green tea reduced gum bleeding.

Tooth Loss

Since green tea is effective for cavity and gum disease prevention, it also prevents tooth loss. A recent Japanese-based study revealed that men and women who drank one or more cups of green tea a day were far less likely to lose their natural teeth.

Gum Disease

Green tea’s anti-inflammatory abilities seem to help control periodontal disease. A Japanese survey of almost 1,000 men found that those who drank green tea regularly had healthier gums than those who didn’t. A German study found similar positive results in people who were asked to chew gum and sweets containing green-tea extracts.

Oral Cancer

The antioxidants and other ingredients found in green tea appear to protect the mouth against cellular damage and cancerous tumour growth. In a study at the University of Texas, green-tea extract was given to patients with precancerous lesions in their mouths, and it slowed the progression to oral cancer.
