The oral health benefits of green tea


Green tea has been extensively studied for its potential benefits on oral health. The beverage contains antioxidants, antimicrobial compounds, and anti-inflammatory properties that can help prevent periodontal and oral diseases. 


Here are some key findings:

  1. Antioxidant Properties: Green tea’s antioxidants, particularly catechins, have been shown to reduce oxidative stress and inflammation, which can contribute to oral health issues like gum disease and tooth decay.
  2. Gum Health: Green tea’s flavonoids have anti-inflammatory properties that can help reduce gingivitis and gum disease.
  3. Cavity Protection: The antioxidants in green tea can help protect against cavities by reducing the acidity of saliva and dental plaque.
  4. Bad Breath: Green tea’s antibacterial properties can help reduce bad breath by killing oral bacteria.
  5. Oral Cancer Prevention: Regular consumption of green tea has been linked to a lower risk of oral cancer.
  6. Periodontal Health: Green tea has been found to promote healthy teeth and gums by reducing inflammation and preventing the growth of periodontal-related bacteria.


However, it is essential to note that excessive consumption of green tea can lead to dental discolouration due to the presence of tannins. Additionally, added sugar in green tea can negate its health benefits and increase the risk of cavities.
