Study found that drinking coffee makes teeth cleaner.

Although many of us drink coffee, some people still think that if you want to keep your teeth white and your mouth fresh, you'd better not drink coffee.

However, a recent study by the Federal University of Rio de Janeiro (Federal University of Rio de Janeiro) found that the higher levels of caffeine in coffee drinks kill a bacterium in the mouth that causes tartar (dental plaque) to form.

Tartar (dental plaque) is a complex biofilm, which is the main culprit of dental caries and periodontal disease. Experiments have shown that polyphenols, a chemical in coffee juice, are constantly attacking tartar-forming bacteria, causing them to break or dissolve. Therefore, to keep your teeth white, drink black coffee, do not add sweeteners, milk, etc., add these things will be counterproductive.

Although the results of this study are exciting, we still want to emphasize that drinking too much coffee can be harmful, such as causing tooth stains and affecting the acidity of enamel.

The main producing areas of robusta coffee beans are in Vietnam and Africa, as well as some parts of Brazil, and their caffeine content is twice as high as that of Arabica coffee beans (Robsta 2.7%, Arabica 1.5%). Robusta coffee has become a drink for those who want to protect their teeth.

Earlier studies have also shown that polyphenols can prevent some oral diseases.
