Which lifestyle change can most significantly impact dental health?

Daily flossing is highlighted as a significant lifestyle change impacting dental health because it directly addresses the removal of plaque and food particles that accumulate between the teeth and along the gumline. This area is often missed during regular tooth brushing, making flossing essential for preventing gum disease and cavities. Flossing helps maintain gum health by reducing inflammation and the risk of periodontal disease, which can have broader implications for overall health.

While increased sugar intake negatively affects dental health by promoting cavity formation, regular exercise contributes positively to general health but does not specifically target dental hygiene. Multiple dental visits promote oral health but aren't a lifestyle change; rather, they are a part of routine dental care. Thus, daily flossing stands out as the most impactful change for maintaining and improving dental health.
