An electric toothbrush is a battery-operated device designed to clean teeth more effectively than a manual toothbrush. It uses rapid bristle movements to remove plaque and food particles, often featuring timers to ensure proper brushing duration. Many models also have different cleaning modes for various needs, such as sensitive teeth or gum care. These toothbrushes typically come with rechargeable batteries and replaceable brush heads, making them convenient and cost-effective over time. Some advanced models even connect to smartphone apps to track brushing habits and provide personalized feedback. Overall, electric toothbrushes can enhance oral hygiene and promote healthier teeth and gums.
