Product Description
Unlike traditional dental floss, the Panasonic Portable dental water flosser and oral irrigator EW-DJ10-W creates rapid, targeted jets of water to comfortably and thoroughly help remove food particles, plaque and bacteria from between teeth and gums and in periodontal pockets. This travel water flosser features a smart, collapsible design to fit into tight drawer or cabinet spaces for storage at home and in bags and luggage for use while traveling. Rotating nozzle directs a powerful stream of water penetrates deep between teeth to wash away the debris, plaque and bacteria everyday brushing and flossing can't always reach. These cleansing pulses also reach just below the gum line to remove trapped food particles and help stimulate the gums. The EW-DJ10-A includes two power settings for individual comfort and needs; a high-speed pulse for normal, everyday cleaning, and a gentler, lower-speed pulse for children and those with sensitive gums. An easy-fill 5.5-Ounce water reservoir lets you floss for up to 40 seconds between fills. The waterproof design rinses clean under running water. To maintain peak performance replace water jet nozzle every 6 months with Panasonic replacement nozzle EW0955W.

First of all, I have found that ANY decent model of oral irrigator / aqua flosser successfully removes more bits of food / debris from between my teeth than simply brushing and flossing alone. Try this yourself by brushing and flossing, and THEN using your oral irrigator/aqua flosser, particularly after a meal which leaves a lot of debris stuck to your teeth and along your gum line, and when you spit into the sink, you will see what I mean. I have only my personal experience to back up this hypothesis, but I strongly believe that persons who use an oral irrigator / aqua flosser regularly after eating will have healthier teeth and gums in the long run than persons who do not use one. I plan on living as long as the rest of my body will allow, so dental care has become a very high priority in my life. Take care of your teeth (and body) now and they will take care of you!
The best thing about using an oral irrigator, perhaps, is that it takes very little additional time out of your day – 30 seconds per session is sufficient in my experience.
I use my oral irrigator after each time I eat (after every meal and snack), allowing me to clean between my teeth, eliminate the buildup of would-be cavity-causing foodstuffs wedged between my teeth and along the gum line, and also avoid excessive brushing (I still brush 2-3x per day).
Combine this oral irrigator with a Sonicare or similar high quality electric toothbrush and Oral B Glide dental tape (wider and more shred-resistant than standard/cheap dental floss – it will remove more debris and is less likely to make your gums bleed), and, depending on your diet, your dentist / hygienist will tell you that you are doing a PERFECT job of taking care of your teeth. I just went in for a dental cleaning – it had been a full calendar year since my last one – and my hygienist reported, highly impressed, that I had very little plaque or tartar and was doing an excellent job at caring for my teeth and gums.
NOW THEN, WHY IS THIS PANASONIC MODEL SUPERIOR TO ITS COMPETITORS?
I see THREE REASONS, right off the bat:
FIRST: it is powered by REMOVABLE AA cell batteries. This means that the life of this oral irrigator is not limited to the lifespan of an internal rechargeable battery. Most models of oral irrigators I have seen rely on internal batteries, which are often Ni-MH or Ni-Cad, which will degrade over time. (In fact, before I bought this Panasonic model, I purchased a Waterpik brand oral irrigator from Target, about 2 years ago. I have been very pleased with this model, but by now the battery life is beginning to diminish noticeably. It still does a great job of cleaning between my teeth and along the gum line, but it is on the decline, and it also takes up twice as much space in my little medicine cabinet as compared with the Panasonic model.)
That being said, I recommend using RECHARGEABLE AA cell batteries, for the savings in $$, time, electricity/energy, and waste, as compared with disposable alkaline AA cells.
AND, if you are traveling internationally and don’t have access to electrical power, you can swap out batteries or find disposable alkaline AA cells in many countries.
P.S. the tool-free battery compartment with O-ring stays tightly shut & waterproof, but is easy to open with a coin or washer or similar item.
SECOND: this unit collapses to take up minimal space when not in use. I find this just as useful when traveling as when I am at home, because it is extremely space-efficient.
THIRD: Because of the way the water intake straw is designed (it is spring-loaded and reaches to the very bottom of the water compartment), this model of oral irrigator provides a steady stream of water until the tank is essentially completely empty. Some other models of oral irrigator, such as my original Waterpik one, do not do so well in this regard.
My only critique thus far is that there is no carrying case included, but for this price point (I paid $27 on Amazon for my Panasonic model in May 2016 and then as a Christmas present for a family member, I bought a second one and paid $30 on Newegg in December 2016 – both quite a bit cheaper than the Waterpik model I purchased a couple of years prior), this is a fantastic model of oral irrigator / aqua flosser, and, hey, Ziploc bags are ubiquitous, cheap, and come in a wide range of sizes. I recommend carrying it in a Ziploc bag if you are traveling between uses, to keep remaining drips of water from spilling into your suitcase / backpack.
And I do like the 2 water pressure settings (low and high pressure), which my original Waterpik model also has.
BATTERY LIFE: I am highly impressed: the first one month of use, “aqua flossing” after each meal and snack, I was able to get an ENTIRE MONTH out of my Panasonic oral irrigator before recharging the batteries. This is WAY BEYOND the capacity of my Waterpik model, which (as stated in the user’s manual) should be charged twice weekly if using it 2 or more times per day.
So there you have it, folks! I rarely write product reviews but have been so mightily impressed by the design and features and capabilities of this Panasonic oral irrigator that I couldn’t help but share my experience with the world. Hopefully it at least inspires you to buy / ask for and begin using an aquaflosser regularly. You won’t regret it, and your teeth and gums will feel noticeably cleaner after each post-meal use.
Best Regards,
David S., Montana, U.S.A.
If you are already familiar with using this type of oral irrigation system, you know it initially may take a little practice to master this form of dental hygiene. But because of this units on and off button, you have complete control of the water flow so keeping your bathroom counter splatter free is so much simpler. This unit gives me confidence that I'm removing food particles that brushing alone misses. And what's notable about this particular model is the technology behind the design. The water is pushed through in microdroplets which can reach deep between gum and teeth.
Bottom line, it's a quality oral irrigation system that performs exceptionally well, looks sleek and modern, and offers the convenience of a charging base. Panasonic also stands behind this product by offering a reassuring 30 day money back satisfaction guarantee along with a two year warranty. I've posted some photos and sincerely hope they help you decide what's best for your needs. Bottom line, I love it and can comfortably and enthusiastically recommend it. Thank you!

The design is extremely clever- collapsing into itself, and even including a little nook to store the nozzle. It's so clever, in fact, that it boggles my mind that they missed one little detail! It started collapsing the first time I used it. This made it quite awkward to use. After careful inspection, it became clear to me that there is no vent at the top of the water reservoir. The result is that air pressure builds up as the water level drops, which sucks the irrigator into the reservoir. DUH!
I can't believe that:
1) The designers didn't consider the basic physics of compressed air when engineering this thing;
2) More people haven't complained about this in their reviews. I didn't read them all, but I read a good bunch. I imagine this would annoy just about anyone.
I drilled a 1/8" hole in the top of the plastic reservoir to relieve the pressure (see photo). Now it works beautifully- no more collapsing. I did make one little error- drilled the hole on the wrong side. No big deal, I just hold my finger over the hole while filling. If you do decide to make this thing perfect though, drill the hole on the side with the fill port. (Panasonic, if you read this feel free to add my improvement. I won't be patenting the process.)

I would definitely recommend this product to anyone with crowns as I find that food gets stuck at the side of them so much more easily than my own teeth and this product has saved me from very painful situations when regular floss did nothing to help! Only thing to watch out for is that this products runs on batteries, instead of being rechargeable. I didn't realise this until I got the product so purchased a battery charger too. Would have preffered a chargeable one, which Panasonic do make as well.
My reason for 4 stars however, is that fact that it is a little difficult to clean. Food pieces have got stuck between the blue and white moving part of the irrigator and its such a narrow space, I haven't been able to get them out. So after a while it has started to look a bit manky!

On occasion I still have to resort to using a disposable flosser. Battery is still going strong after two or more weeks of use. Instructions says do not use re-chargeable batteries, batteries will corrode?
At the price, it's good value
Maybe I will at some point in the future buy one of the more expensive units with a large reservoir.
