The benefits of green tea for dental health

Green tea has been consumed in Asia for thousands of years for its general health benefits, especially for its diuretic and anti-inflammatory effects. But in addition, in recent years some studies have shown its beneficial effects on oral health.

It is true that excessive consumption can alter the color of teeth, so it should be taken in moderation. According to a study conducted in Japan, one cup a day is enough to notice its positive effects in our mouth.

Green tea, originally from Southeast Asia – India, Sri Lanka, China and Japan – does not undergo oxidation during the brewing process, unlike black tea. Thanks to this, it maintains all its properties, since its main components are not altered: vitamins A, B2, C and E, antioxidants (polyphenols) and anti-inflammatory (flavonoids such as catechin).

How does green tea benefit our oral health?

The benefits of green tea for our mouth derive from the positive effects of its main components. According to research published in the Journal of Periodontology, antioxidants inhibit gum-damaging germs, which reduces the likelihood of periodontal disease. In addition, the anti-inflammatory effects of tea are also beneficial to gum health. The catechins contained in tea contribute to the control of oral bacteria and reduce the acidity of saliva and dental plaque, which leads to the development of fewer cavities. Contrary to popular belief, a study published in General Dentistry shows that drinking tea is the same as drinking water for dental plaque: it has no corrosive effects that damage it, unlike carbonated beverages. According to a study published in the Journal of Indian Society of Periodontal, a diluted solution of catechin reduces halitosis. Thus, regular consumption of green tea combats the effect of bacteria that cause bad breath, and that usually accumulate in inaccessible areas of the mouth or dental cavities.

Some recommendations

• Avoid sweetening tea with sugar or honey, as these foods continue to cause tooth decay even when mixed.
• If you do not like tea, try using toothpastes or mouthwashes containing green tea.
• Do not try to solve an oral disease with home remedies. Tea is beneficial, but it is not a substitute for medical treatment or a professional’s prescription.
• Ask your dentist for advice on the most appropriate diet and care for your specific case. Each person has different physical characteristics, general health status and habits that influence their oral health.

In summary, green tea has beneficial effects for health in general, and for our oral health in particular: it helps us to take care of our gums, and to prevent bad breath and tooth decay. Consult your dentist for advice on how and how often you can include green tea in your regular diet.
