Which practice is important for preventing cavities?

Flossing daily is essential for preventing cavities because it effectively removes plaque and food particles from between the teeth, areas that a toothbrush cannot reach. By removing this buildup, flossing helps to reduce the risk of tooth decay and gum disease, both of which are major contributors to cavity formation.

While brushing is important, it is most effective when combined with daily flossing. Many cavities form in the interproximal areas, which are the spaces between adjacent teeth, and these can easily be overlooked if flossing is not performed regularly. Moreover, maintaining good oral hygiene practices, including daily flossing, fosters a healthier oral environment and contributes to overall dental health.

The other practices mentioned do not provide the comprehensive preventive benefits that daily flossing offers. Brushing only before bedtime may leave plaque on teeth during the day, visiting the dentist solely when experiencing pain delays necessary preventive care, and using mouthwash infrequently does not contribute significantly to cavity prevention. Thus, daily flossing stands out as the most effective practice for cavity prevention.
