How Biotene works

Biotene is a proprietary system founded on three enzymes: glucose oxidase, lactoperoxidase and lysozme, each found in healthy saliva. The augmentation of these enzymes through the introduction of Biotene into an oral healthcare regimen aids the symptomatic relief of Dry Mouth. The Biotene range includes mouthwash, toothpaste, gel, spray and gum formulations for convenient, effective relief. New innovation in 2008 added additional enzymes that attack and breakdown plaque biofilm.
