AktivOxigen drops, also called AktivOxigen Serum, are a powerful form of usable oxygen primarily created for dental health. Oxygen is the 'bane' or enemy of anaerobic bacteria (literally bacteria that hate oxygen). This is a potent fact because most of the bacteria that are believed to cause, gum disease, cavities and even bad breath are almost all considered to be anaerobic in nature. Give the bacteria what they don't like. AktivOxigen is manufactured by therabreath.
