Dr Dental, Cleaning Your Teeth
A major part of cleaning your teeth is your toothbrush. There for in order to maintain a good toothbrush you need to 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.
