Mouth breathing is the part of our breath. We usually breathe through our nose and sometimes when there is congestion in the nose or cold we breathe through our nose. As breathing is a wonderful phenomenon of living creatures. It helps us in acquiring oxygen and releasing our carbon dioxide. We have the tendency to breathe either through the nose or mouth depending on the body condition.
Mouth breathing definition
Mouth breathing can be defined as an act of breathing, which often obstructs the breathing through the nose. In some cases when there is intense mouth breathing, it can be an illness.
It is not always bad. During an intense workout, you breathe through your mouth that gets oxygen faster in your muscles.
Breathing through the mouth during sleep may be an invitation to crooked teeth and bad mouth odor. Often this case includes chronic mouth breathing, which is associated with some other condition.
In children, such breathing may result in facial deformities and poor growth.
How would you know if you are breathing through your mouth?
You may not realize that you are breathing through your nose, especially while sleeping. The people who do mouth breathing have the listed symptoms.
- Bad breath
- Dry mouth
- Dry mouth
- Brain fog
- Tired and irritable feeling

- Slower growth rate
- Intense crying at night
- Dry lips
- The problem in concentrating on studies
- Daytime sleepiness
This is it for the symptoms of adults and children. But the question triggers in mind, what causes mouth breathing?
The possible cause of this condition is obstructed nasal airway. In simple words, there is something that resists the air passing through your nose. If this happens, your body by default activates your mouth to do so.
- Cold, nasal congestion, or allergy
- Enlarged tonsils
- Deviated septum
- Enlarged adenoids
- Benign growth of tissue in the lining of your nose
- The shape of your nose
- Shape and size of jaw
- Tumors (rare)
However, some people do it willingly. Yes, some have the mouth-breathing habit. They breathe through the mouth even when their air passage is clear and no obstruction in the nose.
In some patients with sleep apnea, they usually, breathe through the mouth to accommodate the need for oxygen.
Another reason for this condition can be stress or anxiety. Whenever we feel stressed or anxious, our breath changes. We feel short breathiness and breath through the mouth instead. Stress and anxiety activate the sympathetic nervous system, which results in shallow and abnormal breathing.
Thus, mouth breathing and anxiety are interlinked and require the treatment of anxiety first. Though, the reasons differ from person to person.
What are the risks of mouth breathing?
Everyone can breathe through their mouth, but certain conditions can make it more complex.
- Chronic allergies
- Chronic stress and anxiety

There is no such specific examination for the diagnosis. The doctor might check your nostrils physically to check the cause of persistent nasal congestion.
He may ask you about the difficulty in breathing, any worry or anxiety you are dealing with, or snoring problems. And if you are dealing with bad odor issues, your dentist may diagnose your mouth breathing.
If your doctor or dentist diagnoses swollen tonsils, nasal polyps, or any other condition. They may refer you to an ENT specialist.
Is there any health effect of mouth breathing?
Mouth breathing dries the mouth. As the saliva secretes in our mouth, helps in washing out the bacterias. The dry mouth often results into:
- Badmouth odor(halitosis)
- Periodontal diseases like tooth cavities and swollen gums
- Ear and throat infections
it may decrease the oxygen content in the blood. And often results in high blood pressure and heart problems. Mouth breathing affects lung function and worsens the symptoms in asthma patients.
In children, mouth breathing may take different cognitive challenges such as:-
- Narrow mouths
- Poor posture
- Dental malocclusion
- Gummy smiles

Yes, you can prevent mouth breathing by following certain things. But the issue arises because your nose shape can’t be prevented.
If you are feeling allergy or nasal congestion, due to some respiratory issue, surely you can prevent making mouth breathing habit. So, it is a good idea to improve your breathing techniques and stay away from chronic mouth breathing.
Here are some prevent points you should follow:-
- Keeping your surroundings clean to prevent yourself from allergies

- Do not make it a habit of mouth breathing
Yoga and meditation is the best way to stay out of breathing disorders. Try to engage in such calming and introspecting activities to get rid of mouth breathing as well as stress and anxiety.
Restorative yoga activates your parasympathetic nervous system which then promotes slow breath through the nose.
The treatments depend on the cause of the condition. If this is happening as a consequence of a cold or allergy, then certain medications will be provided to treat the primary cause.
The medication includes:-
- Nasal decongestants
- Some steroidal nasal sprays
Adhesive tapes:- these are the strips which when applied to the bridge of your nose may help in proper breathing through the nose. These adhesive strips are called a “nasal dilator” which helps in decreasing the airflow resistance and makes you breathe more easily through the nose.
If someone has sleep apnea, your doctor may advise you to wear a face-mask which has to be applied at night. This therapy is called continuous positive air pressure therapy (CPAP).
The CPAP appliances bring air to your nose and mouth through the mask. The air pressure keeps your airways away from shrinking and getting blocked.
In children, removal of tonsils and adenoids can treat mouth breathing.
Your dentist may advise your children to wear an appliance to widen the mouth palate and help in opening the nasal passage and sinus.
Certain orthodontic instruments such as braces might help in treating the underlying cause of mouth breathing.
Mouth breathing is a normal pattern of breathing during any intense workout or activity. It helps in getting enough oxygen to our muscles faster. However, it can be chronic in certain conditions. For instance, if a person breathes through the mouth, certain health issues may happen as a consequence. Such as dry mouth, tooth problems, bad mouth odor and in children often results in stunted growth. The primary cause of mouth breathing is allergies, cold, or cough that resists the air passage. Also, some individuals develop the habit of breathing through the mouth. Prevention of mouth breathing includes a clean environment that lessens the chances of an allergy.
