How often should I replace my toothbrush?

By 13th January 2020General Dentistry

While most people understand the importance of regularly brushing your teeth. There is no other activity that is more important if you wish to maintain your teeth and gums. But your daily brushing routine could be less effective than you think, simply because the toothbrush you are using may be too old or worn out.

Replace Your Toothbrush Every 4 Months

We generally recommend that it is advisable to replace your regular manual toothbrush at least every four months. If you brush your teeth more vigorously, your toothbrush may need to be replaced every two to three months. Some toothbrushes have indicators, or colour-coded bristles that wear away and signal when a toothbrush should be changed. Even if your preferred toothbrush doesn’t do this, it is easy to determine when a toothbrush is worn out and less effective. If the bristles on your toothbrush are frayed or bent, it is time to replace your toothbrush. It is important to check your child’s toothbrush more often than your own, as children’s toothbrushes often wear out faster.

Toothbrushes Can Carry Bacteria

You may have heard that you should discard your toothbrush after a period of illness. While it is unlikely that you will re-infect yourself with the same virus from your toothbrush, it is possible for certain bacterial infections to reoccur from using your old toothbrush after completing a course of medication. It is also possible that if you store your toothbrush in the same place as a family member who has recently been sick, the bristles can come in contact and transfer the bacteria. If you are concerned that your toothbrush may have been contaminated in such a manner, the best course of action is to discard it and purchase a new one.
