Natural treatment of Dentin Hypersensitivity

19th May 2020

Omya, the expert in advanced mineral ingredients, has developed Omyadent®200 – OG, a new grade of particles that are highly efficient for desensitizing toothpaste applications. The co-processed mineral has an outer shell of hydroxyapatite, the main constituent of enamel and dentin, and can therefore interact with the tooth surface to make it more resistant to painful stimuli.


Produced using Omya proprietary technology, in which the mineral is modified so that new surface features develop and particles become porous, Omyadent® 200 - OG has been specifically developed to address dentin hypersensitivity (DH). This discomfort is as a result of exposed tubules within dentin, most commonly due to receding gums or enamel wear. Symptoms are characterized by a reaction to certain triggers, such as hot, cold, sweet or sour foods and beverages. This can induce the movement of fluid within the tubules, aggravating nerves in the pulp and causing short, sharp pain. As a result, those affected start to avoid certain products, which negatively impacts their quality of life. Dentin hypersensitivity can be treated by blocking dentin tubules, therefore preventing stimuli and dentinal fluid movement. Thanks to its tailored small particles, Omyadent® 200 - OG penetrates the tubules and effectively occludes them, while the hydroxyapatite shell makes it resistant to acid attack.
