Why do you have to brush your teeth gently up and down as well as across the surface?

Brushing your teeth gently up and down as well as across the surface helps ensure that all areas of the teeth and gums are cleaned effectively without causing damage. This technique removes plaque and food particles while minimizing the risk of gum irritation or enamel wear. Additionally, it promotes better oral hygiene by reaching different angles and surfaces, contributing to overall dental health. Proper brushing technique is essential for preventing cavities and gum disease.
