"I brush my teeth properly every day, so my mouth is clean." If that's what you believe, you're exactly the person who needs to try this device. And then despair.
Panasonic's "Jet Washer Doltz." This is a device that uses a powerful stream of water to physically blast away the gunk lurking between your teeth and in your periodontal pockets — places a toothbrush can never reach. Use it right after a thorough brushing session, and an unbelievable scene will unfold in your sink. "I just brushed — why is food debris still coming out?" That shocking truth confronts you, brutally, with just how incomplete your tooth-brushing has been all along.
| The Legendary "Crayfish Smell" Whispered About Online

What catapulted this product to fame is a certain rumor whispered across social media and message boards. "The first time I used it, my mouth smelled like a dead crayfish." "It was like sewer water came pouring out."
It may sound like an exaggeration, but it's a reality experienced by many users. When years of accumulated plaque and pus tucked between teeth and gums get flushed out all at once by the water stream, they release a powerful stench. But that smell is precisely the "proof that the gunk came out." After a few uses, that smell vanishes as if it were never there, and your breath becomes clear and odorless. The horror of having harbored that stench in your own mouth — and the bliss of being rid of it. This is the single greatest appeal of the Doltz.

Jet washers come in two types: large-tank "stationary" models and portable "handheld" models. For beginners, we recommend the "EW-DJ55 (handheld)" featured here.
The reason is simple: "Because you can use it in the bath." Until you get the hang of it, the force of the water stream will get the better of you, leaving your bathroom in a flooded disaster. With this fully waterproof model, you can use it boldly — like a shower — while you're already taking a bath. Thanks to ultrasonic water-stream technology, it also delivers cleaning power on par with stationary models despite its compact size. You can take it on trips and business travel, making "oral cleansing" possible anytime, anywhere.
| The Moving Disappearance of That "Morning Stickiness"

You'll feel the effects of the Doltz most powerfully "the next morning." That distinctive stickiness in your mouth when you wake up, and that unpleasant morning breath. Use the Doltz before bed, and these are reduced to a stunning degree.
You'll wake up with a refreshed feeling, as if you'd just brushed your teeth moments ago. Watching in the mirror as your gums tighten up and return to a healthy pink hue becomes a daily pleasure. Beyond preventing periodontal disease, you'll never again be disheartened by the smell of your own breath inside a mask.
| For Everyone Who "Breathes"

This product brings a revolution especially to people like the following:
- People with crooked teeth, who have spots a toothbrush can't easily reach
- People wearing orthodontic appliances (bridges or wires) who can't get floss through
- People who find flossing or interdental brushes a hassle and can't keep up with them
- People in customer-facing or sales roles who want to be thorough about breath care
| Summary: Protect a Lifetime of Dental Health, with a Stream of Water

Teeth are an organ whose importance you only realize once you've lost them. When you consider the cost of dental treatment and the risk of needing dentures down the line, an investment in the 10,000-yen range is almost absurdly cheap.
A new habit: "high-pressure washing the inside of your mouth." It might hurt at first. There might be some bleeding. But beyond that lies a kind of "true cleanliness" you've never experienced before. Why not say goodbye to the crayfish in your mouth, starting today?
