When you visit the toothbrush aisle at a drugstore, you'll see "Hard," "Medium," and "Soft" lined up side by side. Many men, and anyone chasing that fresh, squeaky-clean feeling, tend to grab the "Hard" option and scrub their teeth with all their might. But did you know that this very habit is actually the leading cause of "receding gums" (gingival recession) and "tooth sensitivity"?
Removing plaque doesn't require force. What you need isn't "power" — it's "density." Once you try CURAPROX, born in Switzerland, a world leader in preventive dentistry, your entire perspective on brushing will be turned on its head. This is no longer a mere toothbrush. It's a "massage machine for your teeth."
| An Unrivaled "5,460 Bristles" — 10x More Than a Standard Brush

The "CS5460" in the product name is a number that represents the bristle count. A typical Japanese toothbrush is said to have somewhere between 500 and 800 bristles.
CURAPROX, true to its name, packs in "5,460 bristles" — roughly 10 times the density. When you see one in person, the bristles are so tightly packed that there's almost no gap between them, creating a surface that feels like "velvet fabric." This overwhelming density catches dirt on the tooth surface not as "points" but as a "plane," gently yet thoroughly breaking down and removing every trace.

So why is it possible to pack the bristles this densely? Because the fibers aren't ordinary nylon. CURAPROX uses its proprietary polyester-based "Curen® fiber."
This fiber is more elastic than nylon and highly water-repellent, so its firmness doesn't change even after absorbing moisture in your mouth. And above all, it is astonishingly "soft." Touch it with your finger and it feels fluffy, like the tip of a paintbrush. Yet each individual bristle has a solid core, allowing it to reliably sweep away plaque. It's a magical material that solves the contradiction of being "soft, yet effective at removing dirt."
| Tackling the Gap Between Teeth and Gums at "45 Degrees"
The most important part of brushing isn't the surface of the teeth — it's the "boundary between tooth and gum (the periodontal pocket)." Brush this area with a hard toothbrush and you'll experience pain, bleeding, and damage to your gums.
But with CURAPROX's ultra-fine, soft bristles, there's no pain at all. Just hold it lightly like a pencil, angle it at 45 degrees against your teeth, and move it gently in small strokes. The 5,460 bristle tips reach deep into the periodontal pockets and lift dirt out as if vacuuming it away. Far from being painful, it feels as comforting as receiving a gum massage.
| Three Months of Durability — and the Fun of Its Design

The price runs from around 1,000 to 1,300 yen per brush. You might think, "1,000 yen for a toothbrush?!" — but the cost performance is actually quite good. Curen fiber is more durable than nylon, and while a typical toothbrush needs replacing after one month, CURAPROX lasts about three months (when used with the proper amount of pressure).
Another draw is its quintessentially Swiss, pop-style coloring. There's a virtually limitless variety of handle and bristle color combinations, and just placing one on your bathroom sink is enough to brighten your mood. Picking a color each morning becomes its own little joy.

Compared to the cost and time of enduring painful dental treatments, investing in your daily toothbrush is the smartest form of preventive medicine.
At first, you may feel like "you haven't really brushed." But run your tongue across your teeth after brushing — you'll be amazed by a smoothness you've never experienced before. Once you've discovered CURAPROX, you'll never go back to those hard, painful nylon brushes again. It's a small companion that will help extend your healthy lifespan.
