(The Answer Might Surprise You!)
Most people don’t think twice about their toothbrush—until the bristles are frayed beyond recognition or it’s been sitting in the same cup for what feels like forever. But here’s the truth: your toothbrush has an expiration date, and waiting too long to replace it could put your oral health at risk. I often get asked, “How often should I really change my toothbrush?” The short answer? Every 3 months. But there’s a little more to the story.
Why 3 Months Is the Magic Number
Over time, the bristles on your toothbrush wear down. They become less effective at cleaning your teeth and gums, and worn bristles can even cause gum irritation. If you’ve been sick, that’s another good reason to swap out your toothbrush. Bacteria and viruses can linger on the bristles, even if they look clean. A fresh toothbrush after an illness helps you avoid reintroducing those germs into your mouth.
Signs It’s Time for a New Brush
You should also pay attention to the way your toothbrush looks and feels. If the bristles are starting to fan out or feel stiff and bent, it’s time for a new one—even if it hasn’t been a full three months yet. Children, in particular, may need replacements more frequently because they tend to brush with more pressure or chew on the brush.
A Simple Habit for a Healthier Smile
Keeping your toothbrush clean and replacing it regularly is one of the simplest ways to protect your oral health. It’s an easy habit that supports everything else we do at your checkups—like preventing cavities, reducing gum inflammation, and keeping your smile in top shape. So the next time you’re in the toothpaste aisle, grab a few extra toothbrushes. Your mouth will thank you.
