Tea is good for your dental health. That’s because it contains fluoride and tannins which work to combat plaque formation and tooth decay. The biggest benefit in this category that comes from tea is that it contains no calories and actually increases your metabolism. The antioxidants contained in Green Tea are believed to have a positive effect on fighting the development of acne and other common skin irritations. It is also an effective tool to use to fight bad breath. A University of Chicago study says bacteria in the mouth that leads to bad breath is no match to the polyphenois that are found in the average cup of tea.
