The Froggymouth Treatment
Froggymouth is a passive functional rehabilitation device that will help your patients with orofacial dysfunctions including Open Bite, Crossbite, Mouth Breathing, Alveolar Deformation, Beckwith-Wiedemann Syndrome, and others. As atypical deglutition or primary deglutition takes place in two stages, (1) creation of the labial seal to isolate the oral cavity and (2) a lingual reverse movement to swallow by pressure difference, but without a seal it is impossible to swallow due to pressure difference.
Froggymouth works as an inhibitor of primary swallowing by forcing labio-labial disconnection. The atypical swallowing sequence is made impossible by forced labial disconnect. Saliva accumulates in your patient’s mouth who must remedy the situation. Your patient must then find a new way of swallowing saliva: Occlusion of the lingual dome against the palate vault. This is the autonomous and spontaneous discovery of secondary swallowing.

Scientific Results – Froggy Mouth
Froggymouth’s breathing and swallowing solutions have been shown to deliver positive results in children, teenagers, and adults with various types of orofacial dysfunctions. Here are the different scientific results.
Using the Froggymouth device only
Case #1 – Anterior Open Bite
In just two weeks, a child’s anterior open bite almost normalised by simply wearing Froggymouth.

Case #2 – Alveolar Deformation

This patient arrived at the age of 5 (photo top left) with dysfunction associated with alveolar deformation. In two months (photo top right) we restored a functional balance thanks to wearing the froggymouth alone and the deformation was reduced by more than half.

He then experienced a spontaneous evolution between his 5 years (photo bottom left) and his 8 years (photo bottom right).
Normalization of functions resulted in a resumption of eumorphic growth and satisfactory dental and occlusal alignment.
Case #3 – Isolated Incisor Open Bite

This four-year-old girl presented with an isolated incisor open bite. She wore the device between March 31 and June 1.

The dysmorphosis continued to correct spontaneously, and the result obtained on October 11 suggests a physiological occlusion in permanent teeth without orthodontic adjustment.
Case #4 – Open Bite and Mouth Breathing

8 years old patient came to the clinic with class II/1 malocclusion with open bite, narrow arches and tongue thrust. After surgical relief of his tongue, we gave him froggy mouth (15 min per day) without any other orthodontic treatment.

The patient was very compliant and wore the froggy on a daily basis. 6 months later, the open bite was spontaneously closed, the arches expanded and the OJ was reduced.
The teeth movement occurred only due to the myofunctional change of the facial muscles and the tongue. At this stage, we started the orthodontic treatment but in a much more favorable situation.
Case #5 – Crossbite

Improvement in the transverse occlusion of a patient after wearing froggymouth for myofunctional rehabilitation. After a period of six months, the occlusion is normalized, results without appliances, fixed or removable.

Paediatric Orthodontics
Case #1 – Maxillary Expansion and Functional Rehabilitation

The froggymouth is of undeniable interest in this clinical case, because it makes it possible to act on the maxilla while re-educating the tongue, which promotes dental proprioception.
By widening the upper jaw at the same time as rehabilitation, we observe spontaneous widening and advancement of the lower jaw. Initially, it was planned to use a device to enlarge the mandible as a second step, but surprisingly, this was not necessary

We carried out the expansion of the upper jaw, used the Froggymouth and the rehabilitation did the rest, that is to say that dental proprioception gradually led to the advancement of the mandible.
Case #2 – Crossbite and Lingual Dysfunction

In this clinical case, we observe a crossbite to the right, a sign of maxillary endognathia.

When the maxilla finally overhangs the mandible, we can optimize the treatment by using the froggymouth device to stimulate rehabilitation and promote dental proprioception…

The initially oblique occlusion plane becomes horizontal when the transverse occlusion normalizes. However, it will still be necessary to intervene, because the patient presents a misalignment of the dental arches indicating unilateral chewing. This problem will need to be handled by another system.
Case #3 – Class III Anterior Cross Bite

This is a class III clinical case (anterior inverted crossbite).
To remedy this, we undertook a three-dimensional orthopedic expansion of the maxilla with an appliance carrying molar elevations.
Subsequently, due to the poor orientation of the upper canines, we continued the expansion hoping for their straightening without elevation.
The froggymouth appliance allowed mandibular adaptation to maxillary expansion.

The patient’s face is now much more harmonious and she seems to breathe more easily through her nose. Treatment progress can be assessed simply by observing the face, even if the eyes are concealed. It is appropriate to follow the evolution of this case over several years, given that the patient is young.

Case #4 – Removable Maxillary Plate and Froggymouth

After a six-month treatment with maxillary plate and froggymouth…

Frequently Asked Questions Use
How to choose Froggymouth sizes?
The Froggymouth comes in three sizes: S, M and L.
The rule: horizontally, the Froggymouth should be smaller than the size of your patient’s mouth so as not to stretch the corners of the lips.
For information:
- Size Small (blue box) fits most children under 13 years old.
- Size Medium (red box), for adults and teenagers.
- The Large size (purple box) is called “large mouth size” and is suitable for a minority of adult patients.
My patient doesn’t have a television at home, what should I do?
The television can be replaced by a computer screen raised to eye level.
Can a book or a tablet replace a television?
No. It is important to maintain a horizontal lingual plane throughout the wearing of the Froggymouth.
Wearing the appliance while reading a book or tablet on the knees would cause the lingual plane to tilt, causing the patient to drool and thus delaying the need to swallow.
Where can I find the rules for using the device?
You can find all the rules for using the device for the patient in this video (1”30).
Share this video with your patients to ensure that the device is worn correctly.
How long does Froggymouth treatment last?
The treatment ends when the position of the tongue is corrected.
Concretely:
You have to ask yourself if your rehabilitation has created an automatism of the new praxis in the patient. This can be assessed by observing your patient in a situation where he/she does not think he/she is being evaluated, or via speech exercise.
As a guide, the majority of treatments last between two and six months. We recommend that practitioners announce a six-month wear to maximise the patient’s compliance.
[For Paramedical Professions] Should I notify the orthodontist when starting treatment with Froggymouth?
We recommend it.
Since the effects of Froggymouth can have a positive effect on the speed and stability of orthodontic treatments, it is advisable to keep the orthodontist informed.
Can Froggymouth be worn in parallel with orthodontic treatment?
The Froggymouth is worn between the lips and is therefore compatible with all orthodontic appliances, except those that do not allow the elevation of the lingual dome, such as the breaker or the quad helix, for example.
In the latter case, you will be able to begin functional rehabilitation only once the breaker has been removed.
Can Froggymouth be worn longer than 15 minutes?
Clinical studies have shown that it is not useful to wear the Froggymouth for more than 15 minutes per session.
However, this does not represent any risk for the treatment.
Generally, wearing it for more than 15 minutes per day should be interpreted as a sign that the treatment is progressing well, as the secondary swallowing is integrated into the patient’s body schema.
Be careful, however, that patients understand that having worn it twice as long one day does not exempt them from wearing it the next day. The Froggymouth must be worn DAILY.
Can Froggymouth be worn at night?
Clinical studies have shown that it is not useful to wear the Froggymouth for more than 15 minutes per session.
However, this does not represent any risk for the treatment.
Generally, wearing it for more than 15 minutes per day should be interpreted as a sign that the treatment is progressing well, as the secondary swallowing is integrated into the patient’s body schema.
Be careful, however, that patients understand that having worn it twice as long one day does not exempt them from wearing it the next day. The Froggymouth must be worn DAILY.
It is not useful to wear the Froggymouth at night.
Indeed, scientific studies have shown that at night, the brain replays the sequences of the day to encode the diurnal acquisitions.
In other words: At night, the patient does not learn, but he/she records what he/she has learned during the day.
Maintenance and Safety
How to wash Froggymouth?
The Froggymouth should be washed with water and toothpaste after each use, then put back in its box once dry.
Read the explanatory brochure carefully attached to the device before use.
Is wearing the Froggymouth device painful?
Wearing the device is not painful.
The vertical separation of the lips causes a change in proprioception that will force the patient to spontaneously find a new method for swallowing.
This discomfort during the first few uses is necessary for treatment and should in no case constitute a reason to stop wearing Froggymouth.
Is it dangerous to wear Froggymouth?
No. The Froggymouth follows rigorous production standards (ISO13485 and ISO9001).
It is made of TPE (thermoplastic elastomers) and contains neither latex nor phthalate.
Each device is individually inspected at various stages of production, including before packaging, to ensure quality.
Is Froggymouth regulated?
The Froggymouth is a Class I medial device.
It holds the marketing authorizations for medical devices in Europe (CE) and the USA (FDA) as well as in most countries around the world. It follows strict production and traceability standards.
Where is Froggymouth made?
The Froggymouth device is produced entirely in France in the Nantes region.
Watch this short video to learn where and how the devices that treat your patients are made.
Indications & Contraindications
At what age can treatment with Froggymouth be started?
From the age of three, it is possible to install a Froggymouth.
Why three years?
The Froggymouth allows the transition from primary to secondary swallowing. It is therefore only useful from the moment when the patient is supposed to have abandoned sucking-swallowing, that is to say after the establishment of chewing and the appearance of the deciduous molars.
Can Froggymouth be used as treatment for adults?
Yes. There is no age limit to start Froggymouth treatment. Orofacial dysfunctions also affect a third of adults.
The Froggymouth comes in three sizes. Typically, size M is suitable for adults.
You can see the results obtained on adults in the Scientific Results section.
What are the indications for wearing Froggymouth?
Poor tongue position is the ideal case for Froggymouth.
It can take several forms: atypical swallowing, mouth breathing, articulation disorders, etc.
Its consequences can be multiple: dental deformations, sleep disorders, postural imbalances, etc.
What are the cases of contraindication to wearing Froggymouth?
The cases of contraindication to wearing Froggymouth are the cases of contraindication to functional rehabilitation.
This involves maintaining sucking habits (pacifier, bottle, etc.), as well as any anatomical environment that does not allow the complete completion of the secondary swallowing sequence.
For example, a palate that is too narrow for the tongue to adopt a high physiological posture, or a major occlusal imbalance (crossbite, overbite) that does not allow stabilization of the mandible by occlusion.
Doesn't the Froggymouth's lips-open position promote the patient's mouth breathing?
No, on the contrary, wearing the Froggymouth helps restore nasal breathing.
Although it is possible for the patient to breathe through the mouth while wearing the Froggymouth, it is the automation of the high tongue posture that will allow the physiological inhibition of mouth breathing.
What percentage of my patients are affected by orofacial dysfunctions?
Reviews of the scientific literature estimate that one in two children (from the age of four), and one in three adults are dysfunctional.
In our patient base, this figure is logically much higher. A literature review published in 2023 in the journal “ l’Orthodontie Française ” highlighted that 85% of orthodontic patients presented with lingual dyspraxia.
The majority of your patients are therefore probably affected by one or more orofacial dysfunctions.
Specific Indication Cases
Can I treat an anterior open bite with Froggymouth?
Anterior open bite is mostly caused by a lingual projection. When swallowing, the tongue enters between the teeth to rest on the labial mucosa and creates this space between the incisors.
Reeducation of the lingual posture with the Froggymouth, if accompanied by abandonment of sucking habits (pacifier, thumb, bottle, etc.), will prevent the worsening of dental deformation. If the rehabilitation is sufficiently early, it will also correct the gap, partially or completely.
Can Froggymouth be prescribed to people with disabilities?
The passive rehabilitation of the Froggymouth makes it an exceptionally good tool for rehabilitating patients with disabilities.
Its limited wearing time, simplicity, non-invasive nature and passive instruction allow for good cooperation from all patients.
Its principle, based on proprioception and inhibition, gives excellent results on patients who have difficulty with awareness of the movements to be carried out in so-called “active” rehabilitation.
Consult the Clinical Cases in the Scientific Results section.
Is Froggymouth effective in cases of hypotonia of the lip and abundant drooling?
The effectiveness of Froggymouth in improving lip tone has been scientifically proven.
A clinical study carried out at the University of L’Aquila, Italy, on 40 patients, by Prof. Quinzi and his teams, demonstrated a 250% increase in initial lip tone (measured in CentiNewton) in patients being re-educated with Froggymouth.
The article and study are available online at PubMed.
Can we work with Froggymouth in case of a joint disorder?
The manifestation of these disorders involves an incorrect position of the tongue. They thus fall into the category of cases of indication of Froggymouth.
However, a severe manifestation of these disorders may require specific work in parallel.
Can Froggymouth be effective in correcting breathing disorders and sleep Apnea?
The correlation between oral dysfunctions and sleep disorders, including OSA, has been highlighted by the work of Prof. Dr. Guilleminault.
We invite you to review the available literature highlighting the impact of switching to automated nasal breathing in all patients with sleep disorders.
The Froggymouth has demonstrated its effectiveness in the rehabilitation of ventilatory function.
Several studies are underway. While preliminary results seem to show a significant reduction in AHI thanks to the Froggymouth port, none have yet published official results. They will be posted on this site as soon as they are available.
