Why You Should Replace Your Toothbrush Every Three Months

I’m sure you’re aware that toothbrushes, like many items in our bathroom cabinets, have a limited life expectancy.

But do you know when you last changed yours? If your answer is no, this blog is for you.

When Should I Replace My Toothbrush?

When the bristles are splayed

The next time you go to brush your teeth take a good look at the bristles. Are they splayed out in all different directions? Does the brush look flat at all?

If you answered yes to either of these questions, it’s possible you’re brushing your teeth a little too hard, causing the bristles to fan out all over the place.  And, the problem with this is that once the bristles are no longer uniform, they can’t clean your teeth properly.

I’ve been told by dentists’ time and time again not to brush too hard. There’s no need as it doesn’t help you clean any better. The bristles are designed to get in and around the tooth, and they don’t require much pressure to do so.

In fact, overenthusiastic brushing can lead to damage. Serious issues such as gum recession and worn enamel are common side-effects of brushing too hard. And, don’t forget, you’ll spend more money replacing your toothbrush more frequently due to it becoming worn down.  

After being ill

It may not have crossed your mind, but if you’ve been ill you could be reintroducing your body to the very same germs and bacteria each time you brush, while also allowing your toothbrush to contaminate others stored in the same place.

When you become ill, store your brush away from any others and when you start to feel better throw it away.

It’s especially important to throw the brush away if it’s something that you’ve been treated for with antibiotics. It’s good practice to start using a new toothbrush two or three days after your course of antibiotics has begun.

Once germs have built up

There are many tips out there to sterilise your toothbrush, such as soaking it in boiling water or even hydrogen peroxide. The truth is though, germs will always find a way to get down into those bristles, particularly at the base.

If you see that your brush is visibly dirty, then you can be sure that on a microscopic level there are some serious germs in there.

Even if you’re regularly cleaning your brush at home, there’s no way you’ll be eradicating all of those microbes where the bristles meet the base of the brush. So, it’s essential to stick with replacing your toothbrush or heads frequently. We recommend replacing it at least every three months.

What Can Happen to Your Mouth If You Don’t Change Your Brush Regularly?

When you don’t change your toothbrush in the recommended timeframe the bristles fray. These bristles then become less effective at removing plaque and food debris around the teeth and in your mouth. As plaque builds up, as does more bacteria, which can cause sore gums and bad breath.

Further to this, the longer you use an ineffective brush, the acid within that plaque will begin to attack the surface of your teeth, leading to tooth decay.

By using an effective toothbrush, you can remove this plaque, before it turns to the hard substance called tartar and mitigate any potential issues.


By using an old, worn toothbrush, all you’re doing is introducing and spreading germs around your mouth. And, since the idea of brushing your teeth is to remove germs and bacteria from your mouth, it’s important to regularly swap your toothbrush.

If you’re not doing this, you risk illness, gum disease, tooth decay and overall poor oral hygiene.
