Rinse your toothbrush with tap water after brushing to remove any remaining toothpaste and debris. Store the brush in an upright position if possible and allow it to air dry until using it again. If more than one toothbrush is stored in the same holder or area, keep the brushes separated.
Do not routinely cover toothbrushes or store them in closed containers. A moist environment, such as a closed container, is more conducive to the growth of microorganisms than is the open air.
Replace toothbrushes every three to four months. The bristles become frayed and worn with use and will be less effective at cleaning teeth. Toothbrushes wear more rapidly depending on factors unique to each patient. Check toothbrushes often for worn bristles and replace them more frequently if needed. Children’s toothbrushes may need to be replaced more frequently
