A natural by-product of S. oralis KJ3^TM is a low-dose of hydrogen peroxide. As this good bacteria is replenished daily, it creates a gradual teeth whitening with the full benefits of long contact times, delivering 24 hour per day coverage of balancing and brightening.

Yellowing, surface discoloration or staining are all results of lifestyle choices: tobacco use, coffee, tea, beets, etc. Anything that stains will affect the color of the teeth. Tooth enamel is porous, filled with microscopic cracks and pores that hold onto staining products. Commercial tooth whiteners employ extremely high levels of harsh, chemical hydrogen peroxide which can actually damage the tooth and create a roughness on the tooth's surface. This increases the film that builds up on the tooth surfaces and in the micro cracks and is available to hold on to stains.

S. oralis KJ3^TM binds to the surface of the teeth, crowding out harmful bacteria by competing for the same nutrients and surface spaces. In laboratory studies, the low-dose hydrogen peroxide produced by the S. oralis KJ3^TM created a continuous whitening benefit that did not plateau over the duration of the study. With daily use, the colonization of S. oralis KJ3^TM provides a constant and expanding population for gradual and continual whitening effects.

The hydrogen peroxide metabolites of S. oralis KJ3^TM also contribute to the breath-freshening features of the ProBiora3 blend by inhibiting the growth of the periodontal pathogens. The decrease in these pathogens results in a substantial reduction in the volatile sulfur compounds associated with bad breath.

Unlike other whitening products, ProBiora3 is completely safe for veneers, caps and dentures.
