In just a few weeks, FroggyMouth stops atypical swallowing and allows secondary swallowing to take place, encouraging nasal breathing.

It is the only device that prevents a lip seal from forming, which is an essential element of atypical swallowing. By preventing any form of sucking, it perpetuates functional reeducation and thus the stability of your treatments.

Designed by Dr. Fellus at Robert Debré Hospital in Paris, France, this device is manufactured entirely in France, complies with ISO13485, and is CE and FDA certified

Faster, more effective and, above all, more stable treatments

Why rehabilitate swallowing ?

For too long we have been content to treat orthodontic issues without paying attention to their etiology, which often leads to relapses. In order to achieve a stable, successful result, the tongue posture must be corrected, nasal breathing must be restored, and contractions of the cheek muscles as a result of treatment must be inhibited.

How can this be achieved ?

The traditional top-down approach first requires an awareness of the patient’s current method of swallowing, then of the correct method. Daily practice of a set of exercises is essential to engram this new praxis. On the other hand, the bottom-up approach focuses on the stimulation of sensomotor areas to enable immediate, unconscious engramming of the new praxis through the creation of new neural circuits.

When is best to intervene ?

As soon as atypical swallowing is diagnosed, it should be treated.

In children aged 4 and up, as well as in adolescents and adults, Froggymouth can be prescribed before, during, and after treatment. It is compatible with all types of treatment:  brackets, aligners, removable retainers, etc.

Don’t let an imbalance in the face and tongue muscles bring the quality of your work into doubt!

Our Goals,

Designed by an orthodontist, for orthodontists, your results are our priority. That’s why Froggymouth focuses on: 

Cooperation is the key to success in functional treatment

  • Daily use is limited to 15 minutes
  • Average treatment duration of 10 weeks
  • Does not interfere with the child’s sleep Explanatory material available for parents

In healthcare, knowledge must be accessible to everyone. That’s why we organize free training sessions during which Dr. Fellus presents his latest work: How does neuroscience help us to better understand how new practices are learned and therefore optimize treatment with FroggyMouth? 

Since FroggyMouth was designed, your feedback, particularly relating to complex cases, has helped us develop the necessary flexibility to treat a wide range of patients.

Therefore, we have set up a personalized follow-up service for your complex cases, allowing you to benefit from Dr. Fellus’ expertise and obtain concrete solutions.


“As Dr. Patrick Fellus says, every labial dysfunction is accompanied by lingual dysfunction [...]. His use of Froggymouth to achieve this as well as the results obtained show this to be the case. […] This little device has already earned its place in the therapeutic arsenal of orthodontists and of speech therapists, too.”

Pr. Jean Delaire

“In the beginning, I was using froggymouth only on the few patients in primary dentition that came to my office […] after having very quick results I tried the device in the meantime of complementary treatments. Today, when I detect a dysfunction, I put a froggymouth”

Dr. V. Azoulay

“My 6 years old son was having more and more problems caused by the pacifier and a low position of the tongue, according to his orthodontist. To close the gap between his jaws our orthodontist gave him a froggymouth, and after 1 month wearing the device, we could already see some improvement. Today, the gap is completely closed.”
