Core Viewpoint - The article emphasizes that not brushing teeth before sleep poses a significantly greater health risk compared to not brushing before breakfast, highlighting the importance of oral hygiene practices. Group 1: Risks of Not Brushing Before Sleep - Not brushing before sleep allows bacteria in the mouth to thrive on food residues, producing acidic substances that erode tooth enamel and increase the risk of cavities [1][2] - During sleep, the absence of food intake and reduced saliva secretion lead to a higher concentration of bacteria, which can cause persistent damage to teeth and surrounding gum tissues, potentially resulting in gum bleeding and bad breath [2][3] - Brushing before sleep is crucial as it minimizes bacterial presence and food residues, protecting teeth during the most vulnerable period [2][5] Group 2: Implications of Not Brushing Before Breakfast - Waking up with a high bacterial load in the mouth is common, but swallowing bacteria with breakfast poses a lesser risk since most are neutralized by stomach acid [3][4] - While bacteria in the mouth do not immediately harm teeth, prolonged exposure can lead to plaque formation and demineralization, making morning brushing necessary [3][4] Group 3: Recommendations for Oral Hygiene - It is essential to brush teeth thoroughly before bed using fluoride toothpaste and proper techniques, such as the Bass method, to ensure comprehensive cleaning [5][6] - Brushing at least twice a day, including in the morning, is recommended to effectively control plaque formation and maintain oral health [6][6] - Regardless of daily busyness, brushing before sleep is highlighted as a critical defense for oral health [6]
