Dentin Hypersensitivity Treatment Methods

Arginine binds to negatively charged tubules, attracting a calcium-rich layer from saliva to infiltrate and block the dentinal tubules, reducing the flow of dentinal fluid in the tubules.

It induces remineralization resulting in occlusion of dentinal tubules.

To drive fluoride ions more deeply into the dentinal tubules that cannot be achieved with topical application of fluoride alone.
