The curious history of the toothbrush
In short: we’ve spent thousands of years looking for ways to clean our teeth. From twigs to sticks, from boar hair to nylon… the history of the toothbrush is more curious than it seems, and in the end it leads to the same thing as always: what matters isn’t the brush, it’s using it well and often.
Before the brush: twigs
Long before anything like a brush existed, people cleaned their teeth by rubbing them with twigs from certain trees, frayed at the tip. The most famous is the miswak, still used in some parts of the world, which has natural antibacterial properties.
The first brush with bristles
The direct ancestor of our brush was born in China more than 500 years ago: a bone or bamboo handle with animal-hair bristles (usually boar). The idea gradually made its way to Europe, where for centuries it was almost a luxury.
The leap to nylon
The big change came in 1938, when nylon bristles appeared: more hygienic, softer and not prone to rotting like animal hair. It’s basically the brush you use today. Everything else (electric ones, heads, hardnesses) are improvements on that same idea.
And today? What really matters
So much history to end up at the basics: a soft brush, used with good technique twice a day, plus floss or an interdental brush. Change it every 3 months (or sooner if the bristles splay), and after a cold. Electric or manual, it doesn’t matter: consistency wins.

Frequently asked questions
When was the modern toothbrush invented?
The first brush with bristles (animal hair on a bone or bamboo handle) was used in China more than 500 years ago. The brush as we know it, with nylon bristles, arrived in 1938. Before that, for thousands of years, people cleaned their teeth with twigs and sticks.
How often should you change your toothbrush?
About every 3 months, or sooner if the bristles look splayed or bent. A worn brush cleans worse. It's also a good idea to change it after a cold or the flu.
Is an electric or a manual brush better?
Both clean well if used with good technique. An electric one helps people who struggle with technique or have limited mobility, but a manual brush used well is perfectly fine. What makes the difference is consistency.
