Recent research presents a convincing case, as green tea specifically – not just hot beverages in general – is tied to a decrease in tooth loss. While warm drinks can rinse your mouth of food particles and residues, the catechins present in green tea have specific antibacterial effects. These molecules decrease the acidity of plaque and saliva, which in turn mitigates the onset of gum disease and tooth decay.
This method of oral health care is attractive not only to those pursuing natural remedies but also to health practicioners in lower-income societies. Where expensive therapies may be out of reach, a simple switch to green tea after a meal can lower the risk of periodontal disease. If your culture doesn’t accommodate a relaxed cup of tea, a quick rinse will also yield benefits.
Good for your body and good for your teeth, small changes we can make in our habits like drinking green tea can contribute to boosting periodontal health. Remember to take your tea without sugar though to ensure the greatest antimicrobial effect and to protect your tooth enamel. Bon appetite!
