A study by Govoni et al. for example shows that the normal NO boosting NO increase in response to a standardized oral nitrate load is markedly attenuated by an antibacterial mouthwash containing chlorhexidine, because "the acute increase in plasma nitrite seen after a nitrate load is critically dependent on nitrate reduction in the oral cavity by commensal bacteria" (Govani. 2008).
This, as well as better-known side effects as antimicrobial resistance, staining, taste alterations, and the mere fact that not everyone likes the burning sensation you get when you swish the mouthwash from one cheek to the other may be reason enough for you to consider using green tea instead.
What a stupid idea? Well, green tea (Camellia sinensis) is not only one of the most popular natural products in the world, its catechins have also been shown to kill Porphyromonas gingivalis (Pg) Prevotella spp and Tannerella forsythus (Tf), as well as to have beneficial effects with respect to the prevention of periodontal disease. The aim of a recent study from the Sri Hasanamba Dental College and Hospital was now to "evaluate the antibacterial efficacy of green tea extract against two primary colonizers in vitro and to evaluate and compare the antiplaque efficacy in vivo" (Das. 2015).
