How to Clean a Toothbrush Properly

Your toothbrush spends most of its time in a damp bathroom. Learning how to clean a toothbrush takes only a minute or two and helps keep it in good shape between replacements. These simple habits are easy to build into your daily routine.

Rinse It Well After Every Use

After brushing, hold the bristles under running tap water. Rinse until all toothpaste and loose debris are gone. Then tap the handle lightly on the sink to shake off extra water.

Store It Upright

Keep your toothbrush upright in a holder or cup with the bristles facing up. Avoid lying it flat on the counter. If several brushes share a holder, make sure the heads do not touch each other.

Let It Air-Dry

Bristles dry faster with good airflow. Try not to seal a wet toothbrush in a closed case or cover, since trapped moisture slows drying. If possible, store it a few feet from the toilet and close the lid before flushing.

Clean It Regularly

Once a week, rinse the brush and wipe the handle with a clean cloth. Wash the holder with warm, soapy water, then rinse and dry it. Skip the dishwasher, microwave, and boiling water, because high heat may warp the plastic and bristles.

Replace It on Time

The American Dental Association suggests replacing your toothbrush every three to four months, or sooner if the bristles look bent or frayed. Replace the brush head on an electric toothbrush on the same schedule.
