To correctly understand this heading:
Remember that any stressed person who continuously clenches his teeth can elicite remote pain and associated dyscomforts from teeth (which are not only painful organs but also tactile one like the thumb and the index in opposite situation)
If You are interested the scientifical data are shown lower.

Comment :

Is there a possible connection between breathlessness and excessive teeth clenching?
In a first analysis, the answer is no. Yet, a close look at the "Neurophysiology" section in our website reveals the extent of territories likely to be reached by information originating from the teeth. Ultimately, teeth clenching has an extremely adverse effect on the respiratory nerve (Cf: the following testimony)

Testimonial :
I, C. P, confirm that the facts described below relative to the pain sequence I experienced as a result of jaw and teeth clenching are true.
In 1993, I was injured in a traffic accident and suffered head trauma and extradural hematoma for which I underwent emergency surgery. I subsequently experienced chewing difficulties (restricted mouth opening). Despite mastication rehabilitation sessions, I gradually developed excessive jaw clenching which by 1998 had produced intense and obsessive clenching of the teeth.

It was not until 2003 that Professor Francis HARTMANN made me aware of the ensuing multiple disorders, as described in this site.
I experienced:
• Chronic itching in the ears, leading to irritation and ultimately to bleeding and rawness;
• Motion sickness, making it uncomfortable to ride as a passenger in an automobile;
• Significant athletic deficiencies including breathlessness, side cramps, dizziness, nausea and blurred vision;
• Strong headaches;
• Violent stomach pains;
• Back and cervical pain;
• Constant need to clear my throat (throat irritations)

The link between these afflictions and the teeth clenching was established in 2008, when they disappeared simultaneously following 5 years of various therapies under the supervision of Professor LN to relieve the jaw clenching. Fifteen years after the accident, I rediscovered the joy of living without discomfort:
• Farewell to head, stomach and back aches;
• Farewell to motion sickness;
• Above all, farewell to fear of breathlessness, nausea and dizziness in sports.
As a young man, I had been active in sports but had stopped as a result of the events described above. I now have recovered my interest in practicing sports.
Friends who had previously struggled to get me to jog only a few kilometers, were stunned with my progress and went so far as to convince me to participate in a 50K endurance race.

After this long therapeutic ordeal, I am extremely grateful to my therapists who not only diagnosed and treated my clenching disorder, but rid me also of the related symptoms and pain for which there was no apparent explanation.
With the hope that this testimony will be of use to you, dear Professor, please accept my sincere greetings and best wishes..


Breathlessness : We have to remenber a structure as called as nucleus tracti solitari (See inthis website: Dictionnary, then Neurophysiology)
Daniel MENETREY has established that trigeminal afferents ( ie: teeth) are able to project in this nucleus. Therefore, are they able to connect themselves to the vagus nerve and particularly to the nervus laryngus superior which is implicated in the respiration ?
A strong and durable clenching could elicit breathlessness. Stopping clenching gives back a normal respiration.




Takemura M, Sugimoto T, Sakai A.(1987) Topographic organization of centralterminal region of different sensory branches of the rat mandibular nerve. Exp Neurol. Jun;96(3):540-57.

The central projection of primary neurons comprising the auriculotemporal nerve, cutaneous branch of the mylohyoid nerve, inferior alveolar nerve, mental nerve, lingual nerve, and buccal nerve was investigated using transganglionic transport of HRP in young rats. In view of the topographic organization of central projection fields, the nerves were divided into two groups; i.e., those projecting to the dorsolateral margin of the trigeminal nucleus principalis, subnucleus oralis, and interpolaris (the auriculotemporal, mylohyoid, and mental nerves) and those projecting more medially (the inferior alveolar, lingual, and buccal nerves). The former group of nerves projected more caudally than the latter in the medullary and spinal dorsal horn complex rostral to the 3rd cervical segment, in general. Furthermore, the latter group projected to the nucleus of the solitary tract and the supratrigeminal and paratrigeminal nuclei, whereas the other nerves did not. The data indicate the following points : Primary neurons innervating the intraoral structures terminate medial (in trigeminal nucleus principalis and subnucleus oralis) and ventral (in subnucleus interpolaris) to the terminal fields of those innervating the facial skin. Primary neurons innervating the intraoral structures project to the nucleus of the solitary tract and the supra- and paratrigeminal nuclei, whereas those innervating the facial skin do not. Primary neurons innervating the periphery of the face project to the spinal dorsal horn and those innervating the intra/perioral region project to medullary dorsal horn, though this segregation from the medulla to the 3rd cervical segment is relatively loose. Only those trigeminal primary neurons, whose receptive fields extend to or beyond the midline, project to the contralateral dorsal horn from the medulla to the 3rd cervical segment.
