It is important to brush your teeth at least twice a day to maintain good oral hygiene. However, brushing more frequently than twice a day is not necessarily better and can actually damage your teeth and gums. Over-brushing can lead to enamel wear, gum recession, and even tooth loss. It is important to use a gentle toothbrush and toothpaste, and to brush in a circular motion rather than back and forth. If you are unsure how often you should brush your teeth, talk to your dentist or dental hygienist. They can help you create a personalized oral care routine that is right for you.
