Bad Breath Research

Welcome to the TheraBreath Research Area. I try to keep this area up-to-date with all the latest news, articles and information regarding bad breath and halitosis. Along with my duties running the California Breath Clinics, I spend numerous hours each month reviewing the latest research and published information on bad breath and halitosis. The TheraBreath Research Area is a selection of articles about bad breath, dry mouth, gum health and general oral care that I've written with the average person in mind. They are intended to help explain the importance of oral health to your overall health and how to best keep your mouth healthy and smelling fresh.
