How Often Should You Change Your Toothbrush?

A dentist has revealed just how often you should switch-up your toothbrush.

Dr Lewis Ehrlich hosts the podcast 'Mouthing Off', where he interviews health and wellness experts about all aspects of living well, health, and lifestyle.

In a recent episode, Dr Ehrlich interviewed his colleague at the Sydney Holistic Dental Centre, Dr Craig Wilson, and the pair answered common questions from listeners about all things oral.

The big question that popped up was about how often should we change our toothbrushes.

"Always go early," Dr Wilson immediately said adding, "we don't sell toothbrushes to make any money so I can promise you that there's no financial motive on that!"

Wilson continued, saying you should check if there are any changes in the brush visually, any distortions in the bristles, you’re well beyond needing to switch up your brush.

“You need to have this particular brush being effective,” he continued, “it needs some level of rigidity but should always be a soft toothbrush. The moment you see the bristles starting distort: change it. You’re far better changing it early than too late.”

He also reminded listeners to clean their toothbrushes, making sure there's no residual debris, toothpaste or foodstuff at the base of the brush, “Don’t let it be a reservoir of bacteria”.

Ehrishlgh also added that if you or anyone in your household has had a cold or flu, it's a good time to change over the brush.

“To be bacteria free, to be virus free is not logical,” Wilson said, “but you can reduce the influence of these things. So we’re meant to be living in harmony with all the viruses and bacteria in the world. We’ll never be clear of these things, in fact, we need them for a lot of processes, but we can minimise the negative effects of a lot of these things."

There were many other tips to make sure you're getting the most out of your toothbrush, and to make sure it's the most hygienic possible.

Storing your brush near your toilet bowl? You probably need to change it more often due to some “spray” that might occur (sorry!).

You should also make sure the brush is completely dry between uses, to decrease the likelihood of mould, and also make sure the brush is in a well-ventilated spot to reduce the buildup of nasties that could be hiding between the bristles.
