Brushing your teeth is essential for maintaining oral health. It removes plaque, a sticky film of bacteria that can cause cavities, gum disease, and bad breath. Regular brushing also helps prevent tartar buildup, which can lead to more severe dental issues. By keeping your teeth and gums healthy, you reduce the risk of infections, tooth loss, and costly dental treatments. Additionally, good oral hygiene contributes to overall health, as gum disease has been linked to heart disease and other conditions.
