How Often Do You Need To Change Your Toothbrush?

Posted on: 25 October 2021

Most dentists recommend that you brush your teeth at least twice a day. If you adhere to these recommendations consistently for a few months, your toothbrush will begin to wear down. The bristles will appear frayed and soft; thus, minimizing their ability to clean your teeth. This is why dentists recommend you change your toothbrush after every three to four months

Below are signs that you need a toothbrush replacement. 

When Someone Else Uses Your Toothbrush 

It's unhygienic to share your toothbrush with others. If someone else uses your toothbrush, you should replace it immediately. The bacteria in your mouth are different compared to the bacteria in your friend's, partner's, or sibling's mouth. Sharing toothbrushes means that you're swapping bacteria with whomever you're sharing with. 

If You Have Been Sick 

Dentists will recommend that you continue brushing your teeth twice a day, even if you're sick. However, this means your toothbrush will be exposed to the same germs or bacteria causing your illness. Using the same toothbrush after recovery may reintroduce the germs and bacteria to your body. To avoid this, you should replace your toothbrush immediately after you recover. 

If Your Toothbrush Touches Another One 

It's not uncommon for people to store toothbrushes in one container, especially if they live together. However, this habit is unhygienic, as the toothbrushes will constantly touch and spread bacteria and germs. 

Toothbrushes touching might seem inconsequential to you, but it could lead to an illness. Therefore, if your toothbrush touches someone else's, consider replacing it and buy a container where you can store yours separately. 

Debris on Your Toothbrush 

If you can notice debris such as toothpaste between the bristles and you can't wash it off, consider toothbrush replacement. Debris buildup indicates that you have had your toothbrush for too long. 

Once you start noticing toothbrush residue along the handle or between the bristles, it's time to toss out your toothbrush. The gunk and debris between the bristles can trap bacteria and germs, making you sick. 

Plaque Buildup 

If you brush your teeth a few times a day, but you notice plaque buildup on your teeth, it's time to replace your toothbrush. Your teeth should be clean after several minutes of brushing. If it takes too long, you need a new brush. 

The bristles have become too soft and can't clean as expected. Replace your toothbrush and watch as you restore the white shine on your teeth. You should also consider visiting your dentist for teeth cleaning to remove the plaque buildup.
