FAQ LyreJet™
Find clear answers to your most common questions and learn how to get the very best from your LyreJet™ for optimal interdental cleaning.
Does LyreJet™ replace toothbrushing?
No. LyreJet™ is not designed to replace toothbrushing. Instead, it cleans the interdental spaces that a toothbrush cannot reach using its unique five-in-one interdental cleaning technology. As a specialist in interdental cleaning, LyreJet™ complements toothbrushing by removing dental plaque from the most difficult-to-reach areas. Toothbrushing and LyreJet™ work together to provide complete oral hygiene.

How long does it take to use LyreJet™?
Just 80 seconds a day are enough to clean and help protect all 30 interdental spaces that your toothbrush cannot reach.
After just a few days of practice, using LyreJet™ becomes quick and intuitive. Spending only 80 seconds a day on complete interdental cleaning—beyond toothbrushing—helps preserve your oral health while supporting your overall health over the long term.
When should I use LyreJet™?
Using LyreJet™ just once a day is sufficient and is recommended by dental professionals. The best time to use it is in the evening, after your last meal and before going to bed, to remove the bacterial plaque that has accumulated between your teeth throughout the day.
Is LyreJet™ easy to use?
Yes. If you've used dental floss before, you'll find LyreJet™ quick and easy to master.
If you've never used dental floss, most people become comfortable with it after just a few days. To make the learning process even easier, dental professionals recommend spending the first one or two days using the LyreJet™ tip and floss without connecting it to the device. This allows you to become familiar with guiding the floss gently between your teeth. Once you're comfortable with the technique, simply attach the tip to the device and enjoy the full LyreJet™ experience.
At what age can children start using LyreJet™?
LyreJet™ can be used once permanent teeth have erupted, although it is generally recommended from the age of 7 or 8. As with toothbrushing, parents should supervise and assist their child during the first few days of learning.
For children, the water pressure should always be set to the lowest level. Because children's gums are naturally thinner and more sensitive than those of adults, this gentle setting is perfectly suited to their needs. The water pressure can then be increased gradually as the child grows.
My gums bleed. Can I still use LyreJet™?
Bleeding gums should never be ignored and should always be assessed by your dentist. In most cases, they are associated with the build-up of dental plaque and tartar, among other contributing factors. After appropriate treatment—usually including a professional scale and polish—you can begin using LyreJet™ gently.
With daily use, LyreJet™ promotes healthier gums through the combined mechanical action of its floss and water jets. As your gums become healthier, bleeding will usually decrease gradually and may eventually disappear once the tissues have recovered.
How long does a LyreJet™ floss last?
The lifespan of a LyreJet™ floss depends on the condition of your teeth. It may last from just a few seconds to several days of use.
The floss is continuously cleaned by LyreJet™'s two water jets during use. If your interdental spaces are healthy and free from sharp edges—such as cavities, tartar deposits, overhanging fillings or poorly fitted crowns—the same floss can usually be used for several cleaning sessions before it needs replacing.
Conversely, premature wear or breakage of the floss is often an indication of these irregularities. In this way, LyreJet™ not only helps clean between your teeth but can also alert you to potential dental problems that should be checked by your dentist.
My LyreJet™ floss always breaks in the same place. What should I do?
If your LyreJet™ floss repeatedly breaks in the same location, it is often a sign of a local irregularity on the surface of the tooth between two teeth. This may be caused by a cavity, tartar build-up, an overhanging filling, a poorly fitted crown, or any other rough surface that can cause premature wear of the LyreJet™ floss.
We recommend consulting your dentist to identify the cause of the problem and, if necessary, correct it.
Why did we choose to highlight exactly 47 benefits?
The 47 benefits presented on this website are not intended to be an exhaustive list. They represent the main clinical, functional and preventive benefits of LyreJet™.
Many other long-term benefits naturally follow, including economic, psychological, restorative and quality-of-life benefits.
Why do gums become stronger?
Just as the skin on your hands or feet naturally becomes thicker when exposed to repeated friction, gum tissue also adapts to regular mechanical stimulation.
The daily passage of the LyreJet™ floss, combined with the gentle massage provided by its two pulsed water jets, progressively stimulates the gum tissues. This natural biological response, known as keratinisation, gradually strengthens the gums, improves their resistance to mechanical stress and enhances their protective barrier against bacterial challenges.
Healthier, stronger gums are less prone to bleeding and contribute to better long-term oral health.
