It may be hard to track just how old it is as even an old toothbrush will still be able to do the function of brushing albeit less effectively. So why not consider some reasons why you should change your toothbrush regularly, doing so will help you to improve your oral health. So, let’s answer the question, “how often should I change my toothbrush?”

When To Change Your Toothbrush

The American Dental Association (ADA) recommends that you replace your toothbrush every three to four months. The same applies if you use an electric toothbrush. Consider some reasons why.

Worn out bristles

Each time you use your toothbrush the bristles will wear out a little bit. You may not realize how worn out it becomes until you change your old toothbrush for a new one. Frayed bristles cannot effectively remove plaque from teeth and gums.


The hygiene of the old toothbrush is another important consideration. Bacteria build up in the bristles over time. You can limit the level of bacteria by placing the brush under running water and drying it after use.  Whilst traveling you should protect the head from bacteria in your bag. It’s also a good idea to change your toothbrush after a respiratory illness. There is a chance of reinfection if you don’t change the toothbrush.

If you have forgotten how old your toothbrush is but you notice that the bristles are frayed or darkened in color (likely due to mold) then it’s time to change your toothbrush.

What Happens If I Don’t Change My Toothbrush Often Enough?

Consider the two points above as reasons to replace your toothbrush.

A worn-out toothbrush cannot remove plaque effectively. This can lead to problems such as gingivitis or even worse periodontitis where there is a chance that your teeth could fall if left untreated.

An old toothbrush is likely to have harbored a lot of bacteria. It stands to reason that this is not going to be good for your oral health exposing your mouth to this bacteria twice a day.

What Toothbrush Should I Get?

Your dentists can help you find a toothbrush that is good for your specific needs. Usually, dentists will suggest choosing soft bristles over hard ones as harder ones can harm your teeth and gums. It’s also recommended to select a toothbrush with a head big enough to brush two teeth at one time.

Some may prefer to use an electric toothbrush. They may feel that they are more effective in removing plaque, stains, and reducing gingivitis.
