Summary by Sections Gum Recession Overview - Gum recession, or gingival recession, refers to the retreat of gum tissue, exposing the tooth roots and potentially leading to tooth mobility and loss [3][4]. - Symptoms include swollen gums, bleeding while brushing, sensitivity to temperature changes, and visible gaps between teeth [6]. Prevalence and Causes - A significant portion of the population, around 50%, experiences gum recession, particularly affecting the aesthetics of front teeth [8]. - The primary cause of gum recession is the accumulation of dental plaque, which leads to chronic irritation and inflammation of the gums [10].
