A damp toothbrush in a bathroom is a place where bacteria thrive. Storing it correctly keeps it cleaner.
- Rinse under running water and shake dry after each brushing.
- Store the brush upright in an airy place, without a sealed cover while wet.
- Never share a toothbrush.
- Replace it about every three months.
A toothbrush touches your mouth twice a day, so how you store it matters. A damp environment lets bacteria and mould grow on the bristles. This article gives simple steps to keep your toothbrush clean, and they are easy enough for anyone to follow every day.
After each brushing
Rinse the toothbrush under running water to remove toothpaste and food debris, then shake off the water. Make sure the water also reaches the base of the bristles, where food particles like to hide. Do not soak the brush in mouthwash or warm water for a long time, because this does not truly disinfect it and makes the bristles wear out faster.
Where to keep it
- Stand the toothbrush upright with the head up so water can drain away.
- Keep it in an airy place and do not seal it under a cover while it is still wet.
- Do not let brushes touch each other when sharing a cup.
- Keep it away from the toilet, because flushing can spray tiny droplets onto the brush.
The cup that holds the brushes should also be washed every week, because the film of water at the bottom is a place where bacteria stick. If you use a travel case, wait until the brush is dry before closing the lid, and take it out again once you arrive.
When to replace the toothbrush
Replace your toothbrush about every three months, or sooner if the bristles are splayed. After an illness such as a cold or sore throat, it is sensible to switch to a new one. If brushes share a cup with other people, separate them and label each one. Never share a toothbrush, because bacteria pass easily from one person to another, and you can read more in our article on whether family members should share a toothbrush.
