• Oral hygiene obviously involves scrupulous toothbrushing, but can also be supplemented by the use of a water flosser.

  • By sending between the teeth a powerful and fine jet of water, this type of device makes it possible to perfect the work, but also to fight against dental plaque.

  • Sold 79 euros, the new model EW-DJ4B-G503 from Panasonic fulfills this mission, with, in addition, the advantage of being nomadic and being able to accompany us everywhere.

Weekend break.

Faced with electric toothbrushes that have become commonplace in travel kits when you go green for a few days, Panasonic offers to combine them with its travel water flosser (ref: EW-DJ4B-G503).

How does this small nomadic device work, which complements toothbrushing in order to guarantee perfect dental hygiene?

Is it really useful?

Better dental oral hygiene

"Irrigator", quèsaco?

This type of device allows you to perfect the brushing of your teeth.

But it does not replace it.

It uses a more or less powerful fine jet of water projected on and between the teeth.

Purpose: to evacuate small food residues that may be there.

The idea is obviously to keep a bright smile (you know, without that little unsightly sesame seed or that little piece of salad stuck between your teeth!).

Even more, by cleaning the periodontal pockets (the gap between the tooth and the gum), the water flosser contributes to better oral hygiene and the reduction of dental plaque.

240 grams in the toilet bag

Faced with standard and sedentary models (sometimes a little bulky), connected to the mains in the bathroom, more and more mobile models like the new EW-DJ4B-G503 from Panasonic want to accompany us everywhere.

Battery-operated, with a recharge time of one hour, the small device (15.4 cm high, 52 mm in diameter) will only slightly weigh down your toiletry bag with its 240 grams.

It's the size of a shaving foam canister.

It has a retractable 150 ml water tank to be filled for each use and a cannula to be plugged into its top.

Use almost anywhere

Attention, its use requires to be above a sink.

Indeed, the water projected into the mouth will have to be evacuated as the cleaning is undertaken.

The operation, which may seem unsavory, therefore requires gradually spitting out the water in the mouth during use.

And we will take care to turn on the irrigator only once its cannula is in the mouth.

Otherwise, you risk spraying water all around you (experienced!).

When tested, this new travel model proved childishly easy to use.

It has four pressure levels to accentuate the force of the jet.

We recommend that you start with the first level and then, if necessary, gradually increase the pressure.

The little tickling felt may seem more or less pleasant, especially when it comes to cleaning the gums, which are naturally sensitive.

In case of bleeding, stop the operation immediately.

40 seconds of cleaning

This one, which must remain rather short, can be satisfied with the water capacity of the tank which offers to the irrigator an autonomy of 40 seconds.

This may not seem like a lot, but our recurring tests during a week of testing allowed us, almost systematically, to clean our mouth in a single pass.

The diameter of the device (52 mm), just under its cannula, may cause concern as to the maneuverability of the assembly at the entrance to the mouth.

Some water flossers, such as the Waterflosser from Waterpik (ref: WP-560EU), notably sold in pharmacies, have a slightly more tapered design.

Here, however, the power of the jet makes it possible to perfectly reach the distant molars without having to introduce, otherwise the cannula, the end of the device into the mouth.

282 grams of paperwork

The effectiveness of the Panasonic EW-DJ4B-G503 water flosser (which has a jet power of 6.6 kgf/cm²; or 6.6 kilogram-force per square centimeter) is very real.

At the end of each use (which does not replace classic brushing), the feeling of having a cleaner mouth was there.

It is regrettable that Panasonic only provides a cannula in the package, while several family members may be called upon to use its water flosser.

Count 6.49 euros for an additional cannula (ref: WEW0984).

In addition, the charger with its proprietary plug must accompany your travels.

A USB-C charge would have been frankly preferable.

And as usual with its devices, Panasonic continues to provide far too much literature: here, the user manual printed in 17 languages, still weighs 282 grams, more than the water flosser which weighs only 240 grams!

Honestly, at the time of scanning QR codes…

Remains a small piece of equipment that is very practical and easy to live with.

What's more, its accessories can be cleaned in the dishwasher.

Sold for 79 euros, the Panasonic EW-DJ4B-G503 water flosser is worth about the same price as its nomadic competitors, which are not very numerous, and some of which operate on batteries only.

Recommendable, the device can also be attractive to people, teenagers or adults, who have orthodontic appliances.

According to an Ifop/SODF survey, more than one in two French people have already had recourse to orthodontic care for themselves or their children.
