How Often Should You Replace Your Toothbrush


Posted on 5/24/2021 by Dr. Burnham
How Often Should You Replace Your ToothbrushEverything has an expiry date, especially hygiene and cosmetic products. While we are particularly wary of what we put on our skin, we tend to ignore our dental hygiene products' expiry date, especially our toothbrush.

Our toothbrush is an essential tool for dental care. It is the primary tool for removing plaque and food bits and pieces from our teeth. Thus, we should pay extra attention to the recommended toothbrush care rules and tips.

When should You Change Your Toothbrush?


According to the American Dental Association, you should change your toothbrush every three months. Studies by dentists and researchers have found that a toothbrush's bristles start to weaken and deteriorate after three months. They lose their effectiveness for plaque removal from the teeth and gums.

If you can't remember how old your toothbrush is, then take a closer look at the bristles. If they look worn out and frayed, you should definitely replace your toothbrush. Discoloured and deformed bristles are also an indication that you need to replace your toothbrush.

You should also replace your toothbrush after recovering from dental, periodontal, and viral infections, including the common cold and flu. Bacteria in your mouth can transfer to the toothbrush and make it a breeding ground for more bacteria. It can also lead to the formation of fungus.

Even during the infection, make sure you wash your toothbrush with water and keep it covered to prevent the spread of germs. If you notice brown spots in the bristles, you need to replace your toothbrush as that is a sign of fungus growing in the toothbrush.

Finding the Right Toothbrush


Everybody has a different dental structure. Thus, there is no set rule or guideline to finding the right toothbrush. Some people require the use of a hard bristle toothbrush, while it may cause gum bleeding for others. You should visit your dentist to ask them for recommendations on which dental products to use.
