“牙龈萎缩"了，还能“长”回来吗？

Core Viewpoint - The article emphasizes the importance of addressing gum recession, which affects approximately 50% of the population in China, and introduces a new toothpaste developed by a team from Peking University that claims to improve gum health and reduce sensitivity [8][12][25]. Group 1: Gum Recession and Its Implications - Gum recession, or gingival recession, is a condition where the gum tissue pulls back, exposing the tooth roots, which can lead to tooth sensitivity and even tooth loss [3][4]. - Symptoms of gum recession include swollen gums, bleeding while brushing, exposed tooth roots, and increased tooth sensitivity to temperature changes [6][10]. - The primary cause of gum recession is the accumulation of dental plaque, which leads to chronic irritation of the gums [10][12]. Group 2: Product Introduction and Efficacy - The product introduced is the Nobida Rebuild Gum Care Toothpaste, developed by a team of PhD researchers from Peking University, which has received clinical validation from dental hospitals [23][25]. - Clinical reports indicate that after two weeks of use, the sensitivity of participants decreased by 39.44%, and after four weeks, it decreased by 56.34% [28]. - The toothpaste claims to reduce plaque index by an average of 90.5% after two weeks of use, demonstrating significant efficacy in improving oral health [33]. Group 3: Unique Ingredients and Technology - The toothpaste utilizes HAP-Rebuild technology, which incorporates hydroxyapatite (HAP), a natural component of teeth and bones, to help reduce plaque and improve gum health [55][57]. - HAP is known for its ability to physically reduce plaque and protect against common oral issues, making it a key ingredient in the formulation [63][68]. - The product is designed to be safe and effective, with third-party testing confirming its ability to inhibit plaque and alleviate gum problems [34][36].
