How often should I replace my toothbrush?

You should replace your toothbrush every 3 to 4 months. Using a toothbrush with frayed or worn bristles will mean that your teeth get a less effective cleaning. Some people will wear down the bristles more quickly and will need to replace their toothbrush more often. You may also need to replace children's toothbrushes more often than adults' toothbrushes. Talk to your dentist if you have any questions about how often you should replace your toothbrush based on your individual needs and brushing habits.
Replace your toothbrush every three or four months, or sooner if the bristles become frayed. A worn toothbrush will not do a good job of cleaning your teeth. Children's toothbrushes often need replacing more frequently than adults because they can wear out sooner.
