The Canada Dental Network wants to inform you of the signs you should be aware of when it’s time to replace your toothbrush.

Have you ever thought about the germs and bacteria that collect over time on your toothbrush? You meet your toothbrush every morning and every night but yet remembering to change it periodically can easily be forgotten. Our dentist directory in Toronto wants to inform you of the signs you should be aware of when it’s time to replace your toothbrush. As well, let you in on the secrets on how to take care of your toothbrush to make sure you get the most use out of it.

Bacteria on Your Toothbrush

The largest source of bacteria that lands on your toothbrush comes from your mouth. This is because day to day your mouth is exposed to a variety of substances like the food you eat and the beverages you consume. Your toothbrush is also used to clean the build-up of plaque in your mouth and odor-causing germs. In all cases, there will always be bacteria on your toothbrush as it creates a moist environment great for bacteria to live and grow.

Have you ever thought about where you store your toothbrush? You may not want to think of it but you should never store your toothbrush within feet of the toilet. This is because the tiny droplets of water that splash up after you flush can end up floating in the air and land on all surfaces including your toothbrush.

Time to Get a New Toothbrush

We recommend changing your toothbrush every three to four months. Once you reach the three to four month period your toothbrush will start to fray and become less effective. This rule is broken when it comes to kids. This is because since kids tend to brush their teeth harder it causes the toothbrush to wear down faster resulting in needed a new toothbrush sooner. This rule also does not apply if you recently have just been sick. After being sick your toothbrush should be one of the first things to go into the trash to eliminate all those germs.

You might feel that your smile and teeth look clean but if you have a frayed toothbrush that it is not reaching in on all the small spots it once did, they will not be clean. Be sure to keep an eye out for when your toothbrush bristles become out of uniform with the rest.

Taking Care of Your Tooth Brush

Taking care of your toothbrush often gets pushed to the side in your mind as it is not one of your top priorities in your monthly tasks. The Canada Dental Network wants to stress to you the importance of taking care of your toothbrush in small ways to have big impacts on your oral health.

Storing Your Toothbrush Correctly

You never want to store it in a closed container as this can cause bacteria to live and grow. Its best to keep your toothbrush upright and not enclosed to you give it time to breathe and completely dry out. Note that when traveling you should always get in the habit of using a case to protect your bristles and keep the case open after each use to ensure it has time to dry between sessions.

Rinse Your Toothbrush

Remembering to rinse your toothbrush in the tap water long enough to know that all the remaining particles are gone is very important. Washing away what’s left of the food, toothpaste, and saliva can help to ensure the next time you pick up your toothbrush you can have a clean wash.

Keeping It In a Safe Space

Making sure your toothbrush is not touching another is crucial to limiting the germs and bacteria. If you are keeping your toothbrush in the same cup as someone else’s and they touch, your toothbrush is instantly going to have twice as many germs. As well this becomes important as if your gums are scratched open; the other toothbrush could have germs that can carry over to you through this open wound very easily. This rule applies as well when you share a toothbrush with someone else. You should never share a toothbrush with anyone else.


Next time you’re at the store think about picking up a few extra toothbrushes just to have around the house for you and your family. By investing a small amount of your time in paying attention to your toothbrush you are keeping your teeth cleaner and healthier than ever.
