• Rinse your toothbrush with warm water after each use.
• Store in an upright position in the open air to dry. Avoid touching other toothbrushes — and don’t cover your toothbrush. Covered brushes stay wet longer, and bacteria love moisture.
• Get a new toothbrush or toothbrush head every three to four months or sooner if the bristles look frayed or worn.
• Consider signing up for a subscription service to automatically receive replacement heads for your electric toothbrush.
Avoid germs by storing your toothbrush far enough from the sink to prevent splashing and at least four feet away from the toilet to prevent worse. And don’t forget to close the toilet lid before flushing.
