How often do I need a new toothbrush?

The Australian Dental Association (ADA) recommends switching to a new toothbrush every three months. You should replace your toothbrush earlier if it’s showing signs of wear and tear.

There are also cases when you might need to replace your toothbrush sooner. If you don’t replace a toothbrush or electronic toothbrush head when it needs to be, it can affect your dental health and spread infection

Note that if your toothbrush is starting to look the worse for wear before the three-month mark, this could be a sign that you’re brushing too vigorously. This might damage the enamel layer of your teeth and your gums, so be sure to brush in small, gentle circles with light pressure, rather than scrubbing back and forth ask your dentists to show you how at your next dental visit.

Replace your toothbrush after an illness

It is recommended to replace your toothbrush after an illness or a cold sore. Your trusty toothbrush can hold bacteria and viruses for days, which may reinfect you. The same goes for a cold or flu virus.

Remember, it is not the length of time the brush has been used that is important: it is the condition of the bristles that determines when you should replace the brush.

We recommend brushing your teeth twice each day for two minutes each time. Using a soft-bristled brush and following these guidelines means your brush should last about three months before needing replacement. 

However, for people who like to brush more often, say three or four times each day, more frequent replacement might be necessary.

Brushing your teeth twice a day is just one component of keeping your teeth healthy and preventing gum disease. You should also clean between your teeth daily, limit sugary beverages and snacks and see your dentist regularly.
