“牙龈萎缩"了，还能“长”回来吗？

Core Viewpoint - The article emphasizes the significance of gum health, particularly focusing on gum recession, its causes, symptoms, and the innovative solution provided by the Rebuild toothpaste developed by a team from Peking University [4][10][12]. Group 1: Gum Recession and Its Impact - Gum recession, or gum shrinkage, exposes the tooth roots, leading to potential tooth loosening and loss [3][4]. - Approximately 50% of the population in China experiences gum recession, which can affect aesthetics and lead to visible gaps between teeth, known as "black triangles" [8]. - Symptoms of gum recession include swollen gums, bleeding while brushing, tooth sensitivity, and loose teeth [6]. Group 2: Causes and Prevention - While aging contributes to some degree of gum recession, the majority is attributed to plaque buildup, which causes chronic irritation to the gums [10]. - Effective oral hygiene practices, including proper brushing, can help prevent further gum recession and associated dental issues [12][14]. Group 3: Product Introduction and Efficacy - The Rebuild toothpaste, developed by a Peking University doctoral team, is clinically validated to improve oral health and reduce sensitivity [23][25]. - Clinical trials showed a 39.44% reduction in sensitivity after two weeks and a 56.34% reduction after four weeks of use [28]. - The toothpaste utilizes HAP-Rebuild technology, which incorporates hydroxyapatite (HAP), a natural component of teeth, to combat plaque and support gum health [48][50]. Group 4: Unique Selling Proposition - The Rebuild toothpaste claims to physically reduce plaque and alleviate common oral issues without damaging tooth enamel, unlike many whitening toothpastes that can be abrasive [70]. - It is positioned as a safe and effective solution for individuals with sensitive gums, offering a long-term approach to oral care [76][78].
