– restore nasal breathing

– stabilize treatments


The first passive reeducation device for oral and facial functions

Froggymouth is a reeducation device for lingual posture and nasal breathing. Worn for 15 minutes a day for a few months, it stimulates optimum natural development of buccolingual functions and reestablishes functional balance.

By preventing contact between the upper and lower lips, this medical device makes atypical swallowing impossible. This physical impossibility is the starting point of a neural chain reaction described by Eric Kandel, winner of the Nobel Prize in Medicine in 2000. The Froggymouth concept has been successfully tested at Robert Debré Hospital since 2006 and can now be found in 23 countries.

Rehabilitation of the buccolingual functions by Froggymouth is considered to be passive because it does not require any active participation or repeated daily exercices.

“The earlier we treat, the better the patient's face adapt to our plan. The later we treat, the more we have to adapt to fit the patient's face”

Why does lingual posture need reeducating?

The tongue is the most powerful muscle complex in the human body. It is involved in the swallowing process more than 2,000 times a day, but it is also involved in breathing and speaking – so it shapes our orofacial anatomic environment. An inappropriate tongue position can cause various deformations and pathologies: teeth coming in sideways, speech disorders (lisp), mouth breathing which can lead to infectious diseases in the short term such as ear infections, postural deformations and chronic diseases (sleep apnea).


How do you reeducate the tongue’s position?

Myofunctional therapists  are specialists in orofacial reeducation. These professionals use various methods that can be classified in two complementary approaches. The first consists in repeating a series of exercises consciously at short intervals. That’s the top-down approach. The second approach consists in modifying proprioception, whether conscious or not, of the position of parts of the body – and does not require active participation by the patient. This is the bottom-up approach used by Froggymouth.


What is the role of the parents?

Participation by the patient’s parents or by a third party during Froggymouth treatment is essential to ensure the quality of the results obtained.
The parents must make sure that the device is worn daily for 15 minutes, following the protocol laid down under the Role of the Parents tab.
Once engrammation (creation of a new functional neural circuit) is obtained, the parents will have a surveillance role aimed at ensuring that proper swallowing becomes automatic (use of the new neural circuit).

40% of 4-year-old children are still using primary swallowing. A large majority of them will need orthodontic treatment in adolescence.


“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
"At first I only used it with the rare young children who still had their baby teeth who came to see me […] after seeing the particularly fast results, I also tested it alongside my treatments. Now, as soon as I detect a dysfunction, I have the Froggymouth reflex."
Dr. V. Azoulay
"My 6-year-old son was accumulating problems due to extended use of a pacifier and an excessively low lingual position, according to our orthodontist. Our orthodontist prescribed Froggymouth for my son to close the gap between the upper and lower jaws. After 1 month of use, we could already see an improvement and today the gap is completely closed."
