Bad oral bacteria (anaerobic) can not live or grow in the presence of oxygen.
Most oral disorders are caused by those harmful bacteria so called anaerobic bacteria; tooth decay, gingivitis, parodontitis, bad breath, ….
Those bacteria live in an oxygen-poor or even in an oxygen-free environment.
The feature of these microorganisms defines that oxygen is a threat to them.
The active oxygen in the O7 Active® helps specifically to fight these anaerobic bacteria.
