You use your toothbrush every day (hopefully twice), but you may not think about replacing it very often. Most people wait until it’s completely worn out and falling apart, but can waiting too long actually put your oral health at risk? Continue reading to learn why it’s best to swap out your brush and discover the signs to watch out for.
Why Is Changing Your Toothbrush Important for Oral Health?
Your toothbrush is your first line of defense against plaque, bacteria, and food particles. But over time, the bristles lose their shape and cleaning power. When that happens, it limits your ability to brush away harmful buildup, which can lead to cavities, gum disease, and bad breath.
Worn or dirty toothbrushes can also be riddled with bacteria, especially if they’re not stored properly. By changing your toothbrush regularly, you’re protecting your oral health by eliminating a source of bad germs.
The Three-Month Rule
The American Dental Association recommends replacing your toothbrush (or electric toothbrush head) every three to four months. That’s about how long it takes for the bristles to fray, flatten, and lose their effectiveness. If your toothbrush already looks worn out before the three-month mark, you may be brushing too hard!
Can You Just Sanitize It Instead?
Rinsing your toothbrush thoroughly and letting it air dry upright is usually all you need. Some people soak their brushes in mouthwash or hydrogen peroxide, but this won’t extend their life by much. If you’re cleaning it constantly just to make it feel usable, it’s probably time for a new one.
Signs It’s Time to Toss Your Toothbrush
Not sure if it’s time to part ways with your brush? Here are some signs to watch for:
- Bristles are frayed, bent, or flat
- There’s a weird smell or buildup near the bristles
- The brush feels “gross” to the touch or feels bad to brush with
Even if your toothbrush looks fine, bacteria can build up over time. This is especially true if you brush while sick. It’s best to throw it out after you recover to prevent the germs from making you sick again.
Keeping up with regular toothbrush swaps is an easy, affordable way to protect your oral health. With better bristles, you’re more likely to remove plaque effectively, reduce gum irritation, and prevent cavities. So next time you’re restocking toothpaste, grab yourself a new brush too. Your mouth will thank you for it.
