In a word, yes!

Bad breath, or halitosis, happens when  bacteria and dead skin cells and other organic debris, decay and putrefy,  producing sulfur compounds which give the characteristic bad breath smell.  These bad-breath chemicals can cause breakdown of delicate gum tissues allowing  bacteria and their toxins to enter the gum tissue easier as well as the body’s  circulatory system.                                                           Chronic bad breath should always be viewed as a bad sign  and a risk factor for tissue breakdown and disease. Generally, cosmetic  attempts to mask it with standard mouth rinses fall short of what’s needed to  cure bad breath and rid oneself of the                                  bacteria which causes it.
