“牙龈萎缩”了，还能“长”回来吗？

Core Viewpoint - The article emphasizes the significance of gum health and introduces a new toothpaste, Nobida Rebuild, developed by a team from Peking University, which claims to effectively address gum recession and related dental issues through innovative technology and clinical validation [2][11][28]. Group 1: Gum Recession and Its Impact - Gum recession, or gingival recession, is a condition where the gum tissue pulls back, exposing the tooth roots, which can lead to tooth sensitivity, looseness, and even loss [3][5]. - Approximately 50% of the population in China experiences gum recession, particularly affecting the aesthetics of front teeth, leading to visible gaps known as "black triangles" [7][9]. - While aging contributes to some degree of gum recession, the primary cause is often bacterial plaque accumulation, which leads to chronic irritation and inflammation of the gums [9][11]. Group 2: Nobida Rebuild Toothpaste - Nobida Rebuild toothpaste is developed using HAP-Rebuild technology, which utilizes hydroxyapatite (HAP), a natural component of teeth, to repair enamel and reduce plaque [59][61]. - Clinical trials indicate that after two weeks of use, participants experienced a 39.44% reduction in tooth sensitivity, and after four weeks, this reduction increased to 56.34% [31]. - The toothpaste has been clinically validated by two dental hospitals, demonstrating its effectiveness in improving oral health and reducing gum issues [28][36]. Group 3: Unique Selling Proposition - Nobida Rebuild toothpaste claims to physically reduce plaque and repair damaged enamel without the harsh effects of traditional whitening agents, which can erode enamel [70][81]. - The product is positioned as a cost-effective solution for maintaining oral health, suggesting that daily use can prevent costly dental procedures in the future [91][92]. - The toothpaste is marketed as safe for all users, including pregnant and breastfeeding women, and is backed by a satisfaction guarantee [86][95].
