In aqueous oral care gels the peptide is present as matrix. It binds directly as matrix to the tooth mineral and forms a stable layer on the teeth. [38] This layer does protect the teeth from acid attacks. It also occludes open dentin tubule and thus reduces the dental sensitivity.
A hydrogel is a biphasic material, a mixture of porous and permeable solids and at least 10% of water or other interstitial fluid. [1] [2] ...
P11-4 is an α-peptide that self-assembles into β-sheet amyloids with a hydrogel appearance at low pH. [6] It builds a 3-D bio-matrix with binding sites for calcium ions serving as nucleation point for hydroxyapatite (tooth mineral) formation.

Repeated exposures to a low pH cause the mineral content of the teeth on the outer layer of enamel to dissolve therefore leaving the dentine exposed and leading to hypersensitivity. Other causes include dental bleaching, smoking tobacco (which can lead to recession and therefore sensitivity) cracked teeth and abfraction or grinding of teeth ...
In his clinical practice, Gysi observed that the removal of fluid from the cavity floor of his patients' teeth produced the sharp, short pain of dentine hypersensitivity. He subsequently concluded that drying the cavity fluid caused an interruption in the fluid flow movement within the dentinal tubules. [ 20 ]
