The
LyreJet™
A Major Breakthrough for Your Oral and Overall Health
LyreJet™ is a revolutionary technology designed to provide an unprecedented solution to three major public health challenges:
- Dental Cavities
- Periodontal Disease (gingivitis and periodontitis)
- Focal Infections, which contribute to numerous systemic diseases.
These three conditions share a common cause: inadequate interdental hygiene. In other words, insufficient biomechanical decontamination of the interdental spaces, which become true chronic bacterial reservoirs.
LyreJet™ is the first technology specifically designed to efficiently clean and decontaminate the entire interdental anatomy — an anatomical region that traditional devices are unable to treat in its entirety.
LyreJet™ introduces a paradigm shift in oral health prevention, opening a new path toward protecting overall health.
A Medical Innovation Unique in the World
Protected by 20 international patents, this breakthrough technology represents a historic advance in oral and overall healthcare.
Invented during the 1990s by Dr. F. Barth, periodontist and dental surgeon, LyreJet™ is the result of decades of research, development and clinical evaluation.
"After many years of daily clinical use, the results have exceeded every expectation. LyreJet™ is not simply an improvement of existing methods—it represents a historic turning point in preventive dentistry and the protection of overall health."
— Dr. F. Barth, Inventor of LyreJet™
How Does LyreJet™ Work ?
LyreJet™ Combines the Four Essential Conditions Required for Complete Interdental Plaque Removal

The True Innovation: Biomechanical Synergy
The power of LyreJet™ does not lie in the combination of multiple technologies, but in their unique biomechanical synergy.
Within every interdental space, LyreJet™ orchestrates the action of a vibrating dental floss, two bilateral pulsed water jets, and a powerful hydraulic vortex.
Individually, each of these mechanisms is effective in its own right. Within LyreJet™, they work in perfect biomechanical synergy. Each mechanism amplifies the action of the others, delivering dramatically greater cleaning efficiency, bacterial decontamination, and preventive performance.
The bacterial biofilm is simultaneously:
- disrupted
- detached
- rinsed away
- permanently evacuated from the interdental space
The result is complete interdental cleaning and true bacterial decontamination with major health benefits.
The exclusive synergy of the vibrating floss, bilateral water jets and hydraulic vortex.
Incredibly Simple, Fast and Universal
LyreJet™ acts directly at the core of the interdental space through its two bilateral pulsed water jets, its vibrating dental floss and the hydraulic vortex it generates.
With LyreJet™, interdental cleaning becomes a true biomechanical decontamination process, ensuring optimal prevention.
● Hydraulic Vortex Explained
The two bilateral pulsed water jets cross without coming into contact. As they strike the teeth and the floss, they are deflected into swirling hydraulic vortices that enhance the disruption and evacuation of interdental debris.
● Push–Pull Effect Explained
The lateral movement of the water jets between the teeth creates a push–pull effect that further improves evacuation of interdental debris.
● The Role of the Vibrating Floss
One of the two pulsed water jets strikes the floss 3,000 times per minute, causing it to vibrate while continuously lubricating and cleaning it.
● The Function of the Two Bilateral Pulsed Water Jets
The simultaneous action on both sides of the interdental space allows multiple complementary biomechanical effects to act together within the same anatomical area.
- continuous floss lubrication and self-cleaning
- hydraulic vortex generation
- push–pull effect
- disruption and removal of bacterial plaque
- bilateral stimulation of the gingival papilla
- thorough cleaning of the six anatomical sites comprising the interdental region :
- the contact point
- both proximal tooth surfaces
- both gingival sulci
● Specific Angulation of Water Jets
The specific angulation of the jets was clinically determined to protect the integrity of the epithelial attachment of the sulci and maintain their biological seal.
● Continuous Floss Cleaning
The working section of the LyreJet™ floss remains continuously disinfected, preventing any risk of cross-contamination between interdental spaces. The wire remains clean at all times.
● Water-Based Lubrication
Water lubrication allows effortless passage through contact points without the need for cariogenic wax coatings.
● Revolutionary Synergistic Efficiency
LyreJet™ combines unique mechanical and hydraulic mechanisms to deliver exceptional performance. Its variable-geometry floss closely follows the contours of the teeth, effectively disrupting the bacterial biofilm, while two bilateral pulsed water jets continuously evacuate it from the interdental spaces. The result is thorough cleaning and bacterial decontamination of the entire interdental region.

Why LyreJet™ Is a Major Innovation
Much More Than Complete Interdental Plaque Control...
LyreJet™ introduces a new approach to oral healthcare.
It is the first interdental hygiene device that combines complete biomechanical decontamination of all interdental spaces with progressive biological conditioning of the gingival tissues.
🟢 Biomechanical Decontamination
Complete removal of interdental bacterial biofilm through the combined action of vibrating floss, bilateral pulsed water jets and the hydraulic vortex.
🟢 Progressive Biological Conditioning
Regular floss movement combined with hydraulic massage naturally stimulates gingival tissues, progressively strengthening their resistance and enhancing their protective barrier function.
Welcome to the New Era of Oral Hygiene
LyreJet™ does not replace toothbrushing.
It works precisely where toothbrushes cannot reach.
LyreJet™ and the toothbrush complement each other by acting within their respective anatomical areas.

Complete Dental Plaque Control
63% of dental plaque accumulates between the teeth, where it remains massively and permanently stagnant, causing the majority of gingivitis, periodontitis and focal infections. In contrast, only a small proportion of plaque (37%) deposits on the visible surfaces of the teeth and can be removed by toothbrushes.
LyreJet™ protects you against cavities, gingivitis, periodontal disease and even serious systemic conditions associated with focal infections like never before.
With LyreJet™, you take oral hygiene a decisive step forward, achieving a level of interdental prevention that was previously unattainable.
