Most people are using a toothbrush that's way past its prime.
Here's the rule your dentist follows:
Replace every 3 months. No exceptions.
When bristles start to fray and splay outward, they can no longer reach between your teeth or along the gum line. Cleaning effectiveness drops by up to 30% — and a worn brush can actually scratch your enamel and irritate your gums.
The 3 signs it's time to replace:
— Bristles are frayed or splayed
— It's been more than 3 months
— You've been sick recently
And for kids? Check every 6–8 weeks. They brush harder and wear bristles faster.
Swipe through for the full replacement guide — including what happens week by week as your brush ages.
