Do you know when the last time was that you replaced your toothbrush? For many, the answer is no. Often, toothbrushes are treated as if they are ageless, even though they have an expiration date, just like a medication, vitamin, or beauty product. Like a product you'd put in your body or on your skin, using a commodity beyond its time of intended use rarely results in the desired outcome. To help maintain optimal oral hygiene, use this guide for tips on when to replace your toothbrush and why. 

Why Is Replacing Your Toothbrush Important?

There are several reasons an old toothbrush has no place on your bathroom counter. First, an old toothbrush or toothbrush head will likely have quite a bit of wear. When these plaque fighting bristles are compromised, they can't work effectively. This means your oral hygiene will pay the price, increasing the risk of gum damage, gingivitis and tooth loss. Secondly, the bristles in your toothbrush head begin to harbor germs and bacteria, especially if you've been sick. If your toothbrush isn't able to dry properly, it can even begin to grow fungus. By using an old toothbrush, you may be counteracting your oral care efforts by introducing germs and fungus into your mouth and body.

When Should You Replace Your Toothbrush?

The American Dental Association (ADA) recommends replacing your toothbrush every three to four months, sooner if you notice the bristles have visible wear. This may look like the bristles are fanning out, frayed, discolored or clearly faded from their original color. After about three months, bristles begin to break down, reducing their efficacy. Before you brush, look for signs of wear. To help you remember, set a reminder on your phone every three months or sign up for a subscription that automatically sends you a new toothbrush or toothbrush head when it's time to replace it.
