Daiso Finds #1: The $0.70 Dental Habit I Picked Up at Daiso

A Daiso interdental pick that lasts longer than expected, fits in any travel bag, and somehow became a nightly habit.

I didn’t expect a 70-cent dental pick to become part of my nightly routine. But that’s exactly what happened with a pack from Daiso, Japan’s most popular 100-yen store. I’ve tested plenty of their products over the years, but this is the one that quietly became part of my nightly routine.

It costs about 70 cents. It comes with 60 picks. And it has made a real difference to my dental health.

THE PRODUCT

Daiso interdental picks — 60 count

Price: ~$0.70 (¥110 · as of April 2026) Picks per pack: 60 How long it lasts: ~2 months

• Price converted at approximately ¥159 per USD (April 2026). The yen rate changes, so please check current rates when visiting Japan.

Each pick has two ends. One side is a thin floss thread for cleaning between teeth. The other is a small plastic toothpick for removing larger food particles. Simple, compact, and genuinely useful.

WHAT MAKES IT STAND OUT

The thread doesn’t snap

I’ve tried other interdental picks from different 100-yen shops, and the most common problem is that the thread breaks too quickly — sometimes after just a few teeth. Daiso’s version feels slightly thinner at first, but in practice, it holds up through an entire session. By the time the thread starts to wear out, I’ve already finished cleaning every gap in my mouth. That’s exactly the right amount of durability.

“It’s not the strongest floss I’ve ever used — but it lasts precisely as long as one nightly routine. Which, for a 70-cent pack, is more than enough.”

The toothpick end is plastic, so pressing too hard can feel a little sharp. I only reach for it when something is genuinely stuck — it’s not for everyday gentle cleaning. For that, the floss side does all the work.

VALUE & CONVENIENCE

60 picks for about 70 cents — the math works out beautifully

At one pick per night, a single pack lasts well past the middle of the month — sometimes close to two months. For less than a dollar, I’m getting over 50 nights of reliable dental care. The packaging is compact enough to slip into a corner of a travel bag, which means there’s no excuse to skip the routine even when away from home.

MY EXPERIENCE

Fewer cavities. Fewer dentist visits.

Before I started using these regularly, I was going to the dentist for fillings pretty often. Since adding this to my nightly routine — brushing first, then the interdental pick — I’ve shifted almost entirely to check-up visits only. I can’t say it’s solely down to this product, but the timing lines up.

My routine is simple: brush, then one Daiso pick to clear whatever the brush missed. It adds maybe two minutes and has become as automatic as turning off the lights before bed.

If you’re visiting Japan, Daiso stores are everywhere — look for the red and yellow sign. These picks are in the oral care aisle. At about 70 cents a pack, there’s very little reason not to try them.
