Top Signs Your Toothbrush Needs to Be Replaced

 Azarko Marketing  Tuesday, March 06, 2018

One of the most common questions heard at an Edmonton dental clinic is how to tell that a toothbrush or electric toothbrush head needs to be replaced. After a period of time, toothbrushes become far less effective at removing plaque bacteria from the surfaces of the teeth. An old toothbrush can also become a breeding ground for bacteria, posing a risk to your health. At Azarko Dental Group, our Edmonton dentists would advise you to change your toothbrush if:

  • The bristles are bent and frayed

    One of the best indicators that it's time to throw a toothbrush out is when the bristles are bent and frayed. New bristles are designed to fleck away bacteria from the tooth surface. Worn out bristles, however, will simply bend when pushed against the surfaces of your teeth, scrubbing away far less bacteria.

  • Your toothbrush looks discoloured

    A discoloured toothbrush with debris near the bottom of the bristles which you are not able to remove is well past its expiration date. By this point, it likely isn't providing adequate brushing and may be harbouring bacteria as well. If your toothbrush is discoloured and dirty, you should dispose of it right away.

  • It's been three months since you changed your toothbrush

    Even if your toothbrush doesn't yet look too worn or discoloured, a good rule of thumb is to replace it at least once every three months. After three months, the bristles have likely lost their effectiveness and you'll be leaving more bacteria on your teeth after each brushing.

  • Your toothbrush has been improperly stored

    Your toothbrush needs to be placed upright, uncovered, and away from other toothbrushes after each brushing in order to dry properly. If your toothbrush accidentally leans against someone else's toothbrush, or if it is placed in a drawer or any type of enclosed container, then it's time to swap it for a new one. Likewise, if you are travelling and you find that your toothbrush has tumbled out of its case in your bag, then it should be replaced as well.

  • You've recently been sick

    It is very good practice to dispose of your toothbrush after you have gotten over an illness, especially if it was a bacterial infection such as strep throat. The bacteria can hide in the bristles and it is possible that you might reinfect yourself by using the same toothbrush. It is also a good idea to change your toothbrush after you have had any sort of mouth sore.
