How often should I replace my toothbrush?

Posted by Simon Cooper on


How old is your toothbrush? Any idea?

Life is so busy these days and if you’re like me, buying a new toothbrush often gets forgotten until your bristles look like a tiny food-filled explosion. Having to remember something so mundane is annoying. Let’s face it, a toothbrush is not high on the list of things that are fun to shop for.

But using an old toothbrush is more than just bad for your teeth, gums and general health. It’s also proven to lead to things like dementia and heart disease. Yikes!

Here’s the thing:

You use your toothbrush a few times a day to remove food, germs and plaque from your teeth. And I don’t mean waving it like a magic wand, you’re in there scrubbing madly away for a few minutes each time. Then you scrape the gunk off the back of your tongue with it. (Apologies for how gross this blog is at times.)

After all that, you rinse your toothbrush under cold water, bang it on the sink a few times and put it away. Where? Hopefully in a drawer. But many of us keep them in a cup on the counter. Which is close to the toilet. I’m not going to add more disgust to this post, but if that’s you thing, then read this. The bottom line is that if you take a minute to think about toothbrush hygiene, it’s a bit unsettling.

How often to change your toothbrush

Dentists recommend changing your toothbrush every 3 months. If you notice that your bristles are starting to fray earlier, then consider replacing your toothbrush sooner (every 2 months). 

The reason is that nylon toothbrush bristles wear out and start to damage your tooth enamel and gums. This can lead to periodontal (gum) disease. 

If you forget to change your toothbrush frequently, then consider choosing a Grin toothbrush subscription. We mail your toothbrush to you and send you replacement reminders every 3 months so you aren't damaging your tooth and gums.
