Store toothbrushes upright: rinse, air-dry and replace

For households sharing a bathroom. Prepare toothbrushes, an open ventilated holder and running water; a replacement brush is needed only when due, and prices vary. Based on American Dental Association guidance. This is routine toothbrush care, not an endorsement of sterilizers or brands. Do not keep wet brushes sealed for extended periods or heat them in a microwave or dishwasher.
