Day 2426 - It's time to change your toothbrush

How often do you change your toothbrush?

Getting a new toothbrush is not just about how damaged your bristles get, it's also about the overall "health" of the toothbrush.

Your toothbrush gets wet and is therefore a great place to grow mould and bacteria.  It also goes in your mouth which is a great place to put bacteria, viruses and even parasites into your body.


I know right.  So knowing when to change your toothbrush isn't just about ensuring the bristles are still in good condition for getting your teeth and gums clean, but it's also about your overall health and well being.

First and foremost, do you keep your toothbrush in a toothbrush holder?  When was the last time you cleaned that?

Does your toothbrush have one of those handy cases to enclose the head to keep the germs away? When was the last time you cleaned that?

Do you throw your toothbrush into a drawer that has a lovely toothbrush space? When was the last time you cleaned that?

If you're not cleaning the toothbrush's living space, then there's a pretty good chance your toothbrush is carrying some nasty germs.

In a study conducted by the American Society for Microbiology, researchers found that 60% of toothbrushes tested positive for faecal matter.


Plus, if you're sharing your bathroom with room mates or family they say there is an 80% chance that those germs on your toothbrush (bacteria, viruses and parasites) actually came from someone else.


So what do we do?

Well, the best way to avoid contamination is to clean your toothbrush and its living space (cup, drawer space, little head protector thingy) every few days.  Experts suggest these items get washed in the dishwasher a couple of times a week to really be sure.

They say we should be replacing our toothbrushes every 3-4 months.

I don't know about you, but after reading this I'm thinking I'll change mine weekly.

  1. Not as often as I should - yikes!

  2. I have an electric toothbrush and change my head every two months. :)

  3. Oh god. *boils toothbrushes*

  4. I have a real thing about fresh toothbrushes and change them probably more often than I need too. x

  5. I'm clearly a walking, talking bacteria receptacle. Excuse me while I throw my toothbrush out!

  6. So gross. I've never thought about it before. I think we change our toothbrushes monthly. But I should clean out the top drawer where we store the toothbrushes.

  7. I think I feel ill now. I do occasionally soak ours in listerine, but probably not enough!

  8. Yuck - I change my brush every six weeks or so but clearly there are a whole lot of germs going on. We had our son to the dentist yesterday for his first extraction, so dental hygiene is a hot topic in our household. He's become flossing obsessed!

  9. So gross, isn't it?!! I change mine every season, so I suppose that's once every four months. I don't clean the mug they sit in often enough though.

  10. OMG... 60% contain fecal matter??? I'm buying single use toothbrushes from now on!!

  11. I am pretty terrible at remembering to change mine. But my husband is pretty good so he just changes mine for me!

  12. I must be one of those weirdo's that changes the family set of toothbrushes ALL the time - they kinda freak me out if I don't :(

  13. I got an electric toothbrush for Mother's Day and replacing the brush part is quite expensive! Not sure it's such a great idea now.
