How Often Do I Need a New Toothbrush?

We know and love our toothbrushes as a tool that controls plaque, helps prevent cavities, and freshens our breath. But are we changing this tool at the right time when it loses its effectiveness? Have a look at what DIANA DIZIK, DDS, General & Cosmetic Dentistry wants to share with you.

Toothbrush That Matters

The American Dental Association recommends that you change your toothbrush at least four times per year for proper oral health. This would be approximately every three months. If you use too much pressure when brushing your teeth, you will find that the bristles of your brush start flaring out or fraying before three months. 

Meanwhile, if it has been over five months and your bristles have not frayed, you have not been brushing long enough. Wearing out your toothbrush regularly is a helpful indicator of how well you brush your teeth. Dentists recommend brushing for two minutes to thoroughly clean and strengthen your teeth.  

Nowadays people are opting for fancy stuff. Although it is okay to buy a fancy toothbrush, you should always buy brushes with a head cap. It will keep the toothbrush clean and tidy.

Why Is It Recommended to Regularly Change Toothbrushes?

The mouth is exposed to various types of bacteria. These bacteria make their way to your toothbrush and multiply there if you are not strictly dealing with it. Therefore, the problems that start from the mouth could spread to the stomach and elsewhere. It is possible to clean your toothbrush with warm water, but it is advisable to replace the toothbrush within the recommended time frame.

When the bristles of your toothbrush are worn down, it becomes more difficult to scrape plaque and calculus off of your teeth and gum line. The toothbrush ultimately loses its ability to effectively clean your teeth. 

Protecting Toothbrush From Bacteria

Brush bristles can harbor thousands of microbes and cause varieties of diseases and infections. To prevent your toothbrush from spreading germs, you should:

  • Store your brush vertically in a dry, open area to allow it to completely dry.
  • Use warm water to rinse your brush after use. However, hot water may shorten the toothbrush’s lifespan.
  • Don't let your brush come in contact with other brushes to prevent contamination. 
  • It is wise to practice disposing of your toothbrush after being ill.
