When should you change your Toothbrush?

Did you know that most Americans only switch to a new toothbrush once or twice a year? When in fact, the ADA (American Dental Association) recommends to replace your toothbrush (or brush head if you use an electric one) every 3 months.

Indeed, many dental professionals will confirm that time frame as well: 3 months sounds like the proper time to get yourself a new brush. So… Say good bye to that baby and pamper yourself with a brand new shiny one :)


A common mistake is to think you need to change your toothbrush because of germ build-up. In reality, it is more because of the wear of the bristles: each brushing will break down the bristles a bit more and they will slowly (but surely!) lose their effectiveness in getting to all those tricky corners around your teeth. And no matter what type of toothbrush you are using, they will eventually become frayed and won’t break the plaque and get in places where cavities form, or underneath the gum line as good as they used to, or at least are supposed to.

Thus, worn bristles will NOT clean your teeth and gums properly.

Clinical researches have shown that a new toothbrush can remove more plaque than one that's worn out. So go for that new friend to ensure a healthy smile!

Note: Pay attention to how your bristles look: If they seem tired before 3 months, it most likely means you are brushing too hard. Release the pressure you are applying on your teeth and gums that could cause enamel damage and gum recession.  Yes, it depends on the brusher and not the toothbrush. If you have a heavy hand, the bristles might wear out sooner. Remember that the key determinant is not the calendar but the shape the bristles are in. You need to replace your toothbrush when the bristles spew in different directions, AND you need to be GENTLE. We don’t say it enough…

But what if I got sick before the 3-month mark? After illness, it is recommended to throw away your toothbrush and replace it.

Yes. While a toothbrush like the Mouth Watchers Antimicrobial Toothbrush feature antimicrobial bristle protection* to help keep brush bristles clean between brushing after only 6 hours, these bristles do not kill bacteria in the mouth, protect you against disease or prevent you from getting sick. So we still recommend being diligent and changing your brush regularly for optimum hygiene. So remember, after a cold, flu, a mouth infection, a sore throat or any other oral discomfort, just get in the habit to change your toothbrush.

Little trick for you: I like to time the change of my toothbrush the first day of every season. How easy…

Parental advice: You may want to replace your children’s toothbrush more frequently.  This cute video from Aquafresh explains children why.

Alright, so you get the picture: switch to a new toothbrush if you want that killer smile to last forever and ever and ever…
