When teeth are sensitive, the pain felt is a signal from the nerves within, meaning the vital enamel surface has worn away & the living structures are exposed, making them vulnerable & causing sensitivity pain. Enamel wear occurs over time due to abrasion, attrition or erosion. Abrasion occurs from improper or excessive brushing, flossing & habits like vaping & nail biting. Attrition is the result of teeth grinding & erosion occurs due to acidic foods & drinks but all these processes make teeth increasingly vulnerable, leading to hypersensitivity. Now there is a specially formulated medical toothpaste by REGENERATE (TM) Enamel Science that is clinically proven to treat this hypersensitivity pain. The toothpaste contains NR-5+ technology that, on brushing, has been proven to form hydroxyapatite deep within the dentine, effectively delivering intensive care treatment for hypersensitivity. The minerals formed have the same crystal symmetry & chemical composition as enamel mineral & are able to penetrate up to 30µm deep into dentine to effectively deliver intensive care to treat hypersensitivity. At each use, the NR-5+ intensive care formula forms a fresh supply of enamel minerals that wrap & integrate onto teeth, activating a cycle of enamel regeneration with the exact same mineral of which enamel is made. The exposed living structures are rescued, the pain signals stop & the hypersensitivity is treated. 90% of people who brushed with Regenerate Hypersensitivity Toothpaste are still pain free 12 hours after last use!
