March 9, by P. McKeown; M. Breathing is one of the most vital functions of the human body. Every breath we take can have a positive or negative impact on our bodies depending on how it is performed; and it has been well established that normal breathing should be achieved through the nose. However, it may be detoured to the oral cavity in the presence of an airway obstruction.
The nose adds moisture to the air to prevent dryness in the lungs and bronchial tubes. The 10 best asthma blogs. Gay guys coks Options. A smile team concierge will be in touch very soon to discuss the details of your request. Additionally, doctors and physical therapists may be able to teach a person techniques that can retrain their breathing to help them focus on breathing through their nose instead of their mouth. It also allows you to release carbon dioxide and waste. Etiology, Chick hottest manifestations and concurrent findings in mouth-breathing children. The two most likely explanations for the latter finding are that jaw opening is associated with a posterior movement of the angle deformitu the jaw and compromise of the oropharyngeal airway diameter, and that posterior and inferior movement of the mandible may shorten the upper airway dilator muscles located between the mandible and Experiencd and compromise their contractile force by producing unfavorable length-tension relationships in these muscles. If the tongue rests on top of the bottom teeth, they may not grow as tall as they should, or even Experience mouth breathing and facial deformity inward.

Hoarseness: Mouth fafial can dry out the airways, causing a person to Experkence a hoarse-sounding voice. Normal facial growth and eeformity is reliant upon proper nasal breathing, lip seal, and proper tongue posture. Sleep apnea and snoring is also a concern for those children who are mouth breathers. The effect of mode of breathing on craniofacial growth. May 15, Heat shock protein 70 Experience mouth breathing and facial deformity adenoid regression by preventing apoptosis in hypertrophied adenoid tissue [ 17 ]. Craniofacial team will comprise of pediatrician, pediatric plastic surgeon with expertise in Craniofacial Deformities, neurosurgeon, pediatric dentist, orthodontist, speech therapist, E.
However, some people breathe in and out mostly through their mouth instead.
- Most people do not think about how or how often they are breathing.
- I nfants and children naturally breathe through their noses.
- Breathing provides your body with the oxygen it needs to survive.
The involvement of mouth breathing, facial, and structural growth alterations, especially during childhood has been discussed in medical and dental literature. The relevance of airway obstruction and its assumed effect on facial growth continues to be debated. This study was aimed at assessing the dental and soft tissue abnormalities in mouth breathing children with and without adenoid hypertrophy.
Digital lateral cephalograms were obtained and the dental and soft tissue parameters were assessed using the cephalometric software, Dolphin Imaging All subjects with mouth-breathing habit exhibited a significant increase in lower incisor proclination, lip incompetency and convex facial profile. The presence of adenoids accentuated the facial convexity and mentolabial sulcus depth.
The mouth-breathing syndrome MBS is when a child has mixed breathing i. Exclusively oral breathing patterns are rare or non-existent.
MBS is characterized by disorders of speech organs and joints due to the predominately oral breathing pattern, generally combined with facial deformities, abnormal positioning of teeth and body posture, and with the potential to progress to cardiorespiratory and endocrine disease, sleep and mood disorders and poor performance at school.
Furthermore, MBS is related to genetic factors, unhealthy oral habits and nasal obstructions of varying severity and duration. Hypertrophy of the adenoids and palatine tonsils is the second most frequent cause of upper respiratory obstruction and, consequently, mouth breathing in children. Prolonged mouth breathing leads to muscular and postural alterations which, in turn, cause dentoskeletal changes.
Lymphoid tissue usually develops quickly after birth; it reaches peak size during early childhood and start to regress at around 8 or 10 years of age. In some children, its overgrowth may cause obstruction in the pharyngeal air tract, which may lead to respiratory, sleep, feeding, speech and swallowing disorders.
Oral respiration creates an imbalance in the forces exerted by the lips cheek and tongue; thereby leading to morphological and growth-related changes in the craniofacial complex. This study was conducted to assess the dental and soft tissue abnormalities in mouth breathing children with and without adenoid hypertrophy. The present study was conducted in the Department of Pedodontics and Preventive Dentistry, Yenepoya Dental College on growing children who came for dental treatment were referred to the ENT Outpatient Department of Yenepoya Medical College, Yenepoya University for evaluation after obtaining consent from the parents.
Ethical clearance was obtained from the Ethical Committee, Yenepoya University prior to the study. MB and 10 nose breathing healthy individuals control group. The children who presented with previous history of orthodontic treatment, oral or nasal surgical treatment or bone deformity and muscular dystrophy; presence of any other abnormal habits; cases with history of birth injuries and past illness and absence of healthy first permanent molars were excluded from the study.
The adequacy of nasal breathing was assessed by asking the children to breathe through their nose for 1 min after putting water in their mouth and by fogging or condensation on mirror which was placed both near nose and mouth simultaneously and referred to the ENT Department where a detailed clinical and physical examination was done.
Following which a PA view nasopharynx radiograph was taken to examine the presence of adenoids. The presence of adenoid hypertrophy was confirmed using examination by direct fiberoptic nasopharyngoscopy.
The subjects were made to stand in the cephalostat rotagraph plus with the Frankfort Horizontal plane parallel to the floor and teeth in centric occlusion. Cephalometric assessment was made by means of a combination of manual and computerized methods. The anatomic landmarks of the craniofacial skeleton used for cephalometric analysis are depicted in Figure 1.
The anatomic structures were manually digitized; the points were demarcated and the cephalometric values were measured using the cephalometric software, Dolphin Imaging Landmarks of craniofacial skeleton used for cephalometric analysis.
The various linear and angular dental measurements and soft tissue measurements were recorded as nasal breathers NB and mouth breathers MBA and MB for comparison with cephalometric variables of a normal child. There was a significant increase in the upper incisor and lower incisor proclination seen in both the mouth breathing groups Table 1 , Graph 1.
There was a significant increase observed in the depth of mentolabial sulcus, interlabial distance and facial convexity in mouth breathing children. Comparison of soft tissue angular cephalometric values between mouthbreathers and nasal breathers.
Comparison of the cephalometric variables between the 3 groups using post hoc analysis. Comparison of soft tissue linear cephalometric values between mouthbreathers and nasal breathers. The dental professionals apprehend that faces of mouth breathers might develop aberrantly, possibly because of the disruption of normal functional relationships caused by chronic airway obstruction and altered path of airway and thereby alter the treatment outcome.
Oral respiration, low tongue posture and elongation of lower anterior facial height are apparent at 3 years of age, but more commonly detected after age five. The deleterious impact of decreased naso-respiratory function is virtually complete by puberty.
Hence, the age group years is selected for the present study. The respiratory function and occlusion development relationship is a controversial subject. Authors such as Behlfelt et al. Other authors such as Miller et al. Although studies by Klein 10 and Shanker et al. Clinical assessment to visualize indirectly adenoid tissue in children is not easy to be carried out and sometimes it is even impossible.
Therefore, the radiographic image of nasopharynx in profile allows objective, precise and easy measurements.
It is paramount that the patient is positioned correctly when performing the radiography; patients should not cry or swallow, because they cause an elevation of the soft palate, giving the impression of obstruction. Adenoid palpation is not a reliable method of measurement, and it is very traumatic for children. Radiological imaging provides more information when compared to palpation.
Currently, we have been using the method of visualization of adenoid tissue through endoscopic exams. This exam provides direct and tridimensional image of nasopharynx and its structures. In the present study, bimaxillary proclination and upper and lower incisor proclination was seen in the mouthbreathing children.
The results found in the literature about the inclination of the maxillary and mandibular incisors are controversial because McNamara, 14 Faria et al. However, Solow et al. Our study showed that patients with adenoid hypertrophy presented with proclined maxillary incisors when compared with mouthbreathers without hypertrophied adenoids.
This was not in concordance with the findings of Jakobsen et al. The mouth breathing children presented with a higher degree of the lip separation. According to Trotman et al. The increased interlabial gap may also be attributed to the hypotonicity of the upper and lower lip 2 and increased incisor proclination 22 seen in children with mouthbreathing.
The data of this study was related to the standard cephalometric values of Caucasian population. However, various studies have stated that the standard measurement of one group should not be considered normal for other racial groups.
The present study led to the conclusion that all subjects with mouth-breathing habit exhibited significant lower incisor proclination, lip incompetency and convex facial profile. A multidisciplinary team should work to have early diagnosis and appropriate treatment, preventing the consequent disorders of chronic mouth breathing.
Because upper airway obstruction is an obstacle to normal dentofacial development, mouth breathing children deserve prompt attention before growth has proceeded irreversibly. The early recognition of such facial patterns may be utilized to identify those breathing compromised individuals who are likely to develop such types of malocclusions.
Hence, a joint effort by pedodontist, orthodontist, otorhinolaryngologist and pediatrician is thus required for reducing continuing detrimental effects of breathing impairments on facial characteristics.

Influence of Mouth Breathing on the Dentofacial Growth of Children: A Cephalometric Study
Breathing provides your body with the oxygen it needs to survive. It also allows you to release carbon dioxide and waste. You have two air passageways to your lungs — the nose and the mouth. Healthy people use both their nose and their mouth to breathe. Breathing through the mouth only becomes necessary when you have nasal congestion due to allergies or a cold. Also, when you are exercising strenuously, mouth breathing can help get oxygen to your muscles faster.
In children, mouth breathing can cause crooked teeth, facial deformities, or poor growth. In adults, chronic mouth breathing can cause bad breath and gum disease.
It can also worsen symptoms of other illnesses. The importance of your nose often goes unnoticed — until you have a bad cold. A stuffed-up nose can reduce your quality of life.
It can also affect your ability to sleep well and function in general. Nitric oxide increases the ability to transport oxygen throughout your body, including inside your heart. It relaxes vascular smooth muscle and allows blood vessels to dilate.
Nitric oxide is also antifungal, antiviral, antiparasitic, and antibacterial. It helps the immune system to fight infections. People who breathe through their mouth at night may have the following symptoms:. A child may not be able to communicate their symptoms.
Like adults, children who are mouth breathers will breathe with their mouth open and will snore at night. Children who breathe through their mouths for most of the day may also have the following symptoms:. Children who exhibit problems concentrating at school are often misdiagnosed with attention deficit disorder ADD or hyperactivity.
The underlying cause of most cases of mouth breathing is an obstructed completely blocked or partially blocked nasal airway. If your nose is blocked, the body automatically resorts to the only other source that can provide oxygen — your mouth. Some people develop a habit of breathing through their mouth instead of their nose even after the nasal obstruction clears.
For some people with sleep apnea , it may become a habit to sleep with their mouth open to accommodate their need for oxygen. Stress and anxiety can also cause a person to breathe through their mouth instead of their nose.
Stress activates the sympathetic nervous system leading to shallow, rapid, and abnormal breathing. Anyone can develop a habit of breathing through their mouth, but certain conditions increase your risk. These include:. They may ask questions about sleep, snoring, sinus problems, and difficulty breathing. A dentist may diagnose mouth breathing during a routine dental examination if you have bad breath, frequent cavities, or gum disease.
If a dentist or doctor notices swollen tonsils, nasal polyps, and other conditions, they may refer you to a specialist, like an ear, nose, and throat ENT doctor for further evaluation. Mouth breathing is very drying. A dry mouth means that saliva cannot wash bacteria from the mouth. This can lead to:. Mouth breathing may result in low oxygen concentration in the blood.
This is associated with high blood pressure and heart failure. Studies show mouth breathing may also decrease lung function , and worsen symptoms and exacerbations in people with asthma. In children, mouth breathing can lead to physical abnormalities and cognitive challenges. Poor sleep can lead to:. Treatment for mouth breathing depends on the cause. Medications can treat nasal congestion due to colds and allergies. These medications include:. Adhesive strips applied to the bridge of the nose can also help breathing.
A stiff adhesive strip called a nasal dilator applied across the nostrils helps decrease airflow resistance and helps you breathe more easily through your nose.
If you have obstructive sleep apnea , your doctor will likely have you wear a face-mask appliance at night called continuous positive air pressure therapy CPAP. A CPAP appliance delivers air to your nose and mouth through a mask.
The pressure of the air keeps your airways from collapsing and becoming blocked. A dentist might also recommend that your child wears an appliance designed to widen the palate and help open the sinuses and nasal passages. Braces and other orthodontic treatments might also help treat the underlying cause of mouth breathing.
Treating mouth breathing in children early can reduce or prevent the negative effect on facial and dental development. Children who receive surgery or other intervention to reduce mouth breathing show improvement in energy levels, behavior, academic performance, and growth.
Untreated mouth breathing can lead to tooth decay and gum disease. Poor sleep caused by mouth breathing can also reduce your quality of life and exacerbate stress. If you find that your nose is frequently congested due to allergies or respiratory infections, there are actions you can take to prevent making mouth breathing a habit. Tips for preventing mouth breathing include:. Yoga is beneficial for people who breathe through their mouths as a result of stress because it focuses on deep breathing through the nose.
Restorative yoga is designed to activate the parasympathetic nervous system and promote slower deep breathing through the nose. Aerophagia is the medical term used to describe excessive and repetitive air swallowing. Learn the symptoms, causes, and what you can do about it.
