The science behind Biotène

Biotène contains a blend of moisturisers and lubricants1

Biotène Oralbalance Gel, Biotène Mouth Spray and Biotène Mouthwash contain a high concentration of moisturisers and lubricants that provide oral moisturisation.1 One of these key ingredients is glycerol,1 which acts by forming chemical bonds with water molecules to moisturise underlying tissue by retaining water in the mouth.

Products pH levels

Relief for a dry mouth that helps maintain a healthy oral environment for patients*2–4

*excluding toothpaste

Biotène products have a pH within the range of 6.0–7.8. This helps to maintain a close-to-neutral pH in the mouth, which is a healthier environment for the teeth and oral soft tissues (target normal resting pH 6.3–7.0).2–4

  • Biotène Oralbalance Gel – pH 6.62
  • Biotène Mouthwash – pH 6.0-7.03
  • Biotène Toothpaste – pH 6.2-7.84
  • Biotène Mouth Spray – pH 6.0 -7.0

Biotène products are specially designed for a dry mouth and have a pH similar to natural saliva.
