Review (4/5): I finally ordered it
When I first ordered it, that part of the order got cancelled. Ever since, I have been mixing in green tea extract. , but I finally have actually ordered it by itself. Hopefully it will soon arrive. I know of a couple studies that showed green tea extract with gum also being good in children's teeth., but that is not relevant here.

These 30 patients were randomly divided into three groups using block randomization method. The first group received professional scaling and root planing alone (SRP). The second group (SRP + GT) received scaling and root planing at baseline along with green tea for a period of 6 months. The third group received only green tea (GT) for a period of 6 months without any professional SRP.”
It was observed that the regular oral intake of the green tea led to the improvement of oral health status. All the three groups showed significant (P < 0.01) improvement in all the parameters measured at baseline and compared at 3 and 6 months.”
Used as mouth wash: not as clearly convincing: http://link.springer.com/article/10.1186/2008-2231-20-39#page-1
“Results: Twenty five students were recruited in each arm of the study. A significant improvement was observed in
all periodontal indices during the study (P < 0.001). Two groups were contrasted by changing patterns of alteration
of indices (P < 0.05). Although total amount of improvement was higher in mouthwash group, the differences did
not reach a statistically significant level (P > 0.05, observed power for GI: 0.09, PI: 0.11 and BI: 0.07).”
