Most people prefer keeping their toothbrushes in the bathroom as it’s convenient for them. You can walk into your washroom, brush and then go about your day. However, your dentist might not be very happy with this habit as keeping your brush in the bathroom might expose your toothbrush to “poo particles”.
Dr Payal Bhalla, Principal Dentist and Clinical Director of Quest Dental said: “It is possible for faecal particles (sometimes referred to colloquially as ‘poo particles’) to be present in a bathroom environment, including on surfaces such as your toothbrush. This can occur when toilets are flushed without the lid closed, as flushing can release small water droplets into the air that may contain faecal bacteria and other microorganisms.
She also added, “To minimise the risk of faecal particles coming into contact with your toothbrush, you can follow the hygiene tips mentioned in the previous response, such as rinsing your toothbrush before use, storing it upright, using a toothbrush cover, and closing the toilet lid when flushing.”
She also listed some reasons explaining the reasons why you shouldn’t keep your toothbrush in your washroom.

Humidity in the bathroom

Washrooms are usually humid and this could promote the growth of bacteria and mould on your toothbrush. This can be extremely bad for your health and therefore, you avoid leaving your toothbrush in your washroom.

Aerosolized bacteria

Flushing the toilet with the lid open can lead to tiny water droplets containing bacteria and other microorganisms becoming aerosolized and settling on nearby surfaces, including your toothbrush.

Proximity to the toilet

If your toothbrush is kept close to the toilet, it can come in contact with airborne particles and water splashes, leading to contamination.

Sharing washrooms

When you share your washroom with others, there’s a high chance of cross-contamination. This is because multiple people are using the space and touching various surfaces.
