All About Mouth Breathing Symptoms and Treatments

Breathing is what keeps us alive. It is a subconscious activity, which is carried out by our brain to ensure proper supply of oxygen to our body and for the removal of toxic materials and gases like carbon dioxide. If one fails to learn how to keep mouth closed while sleeping, it could lead them to fatal accidents. Patients suffering from bronchial asthma are often times seen to have shortness of breath which alters their quality of life greatly. Many old age patients are also kept on the ventilator, which is breathing through a specialized machine, because if the body is unable to breathe properly, it may lead to death. This explains to us how important it is for us to breathe.

What Is Normal Breathing?

A normal breathing cycle involves inhaling oxygen from the environment and exhaling carbon dioxide, through the nose. The primary organ for breathing in human beings is the nose. However, in some cases, people normally breathe through their mouth as well. This may happen-

  • After heavy exercise
  • After jogging/running
  • In times of terror
  • After lifting heavy weights
  • While swimming

At all other times, breathing should take place only through the nose. If one is breathing through his/her mouth, it is not normal and should be treated immediately. If not treated, it may lead to fatal diseases including sleep apnea.

Why Do People Sleep With Their Mouth Open?

The mail reasons nasal breathing might be interrupted and people sleep with their mouth open are-

  • The blocked nose is the primary reason for oral berating in most of the cases.
  • In later stages of pregnancy, due to hem dilution, women tend to breathe through their mouth.
  • It could be purely habitual.

Who Can Suffer From Oral Breathing?

Adults and children, both are likely to experience oral breathing. However, the incidence is more common in toddlers and children. It is more common while sleeping at night rather than in the daytime.

Symptoms of Breathing Through Mouth

The key symptom of breathing through the mouth is having a dry mouth and throat on waking up. The severity of dryness is an indicator of the severity of the disease.

Can You Snore With Your Mouth Closed

Yes! You can snore with your mouth closed. Our nose is designed to filter the air as it enters the nose. It also humidifies the air to prevent the nasal passage from drying. Due to extremely dry weather and/or damaged nasal humidification system can also cause medium to heavy snoring effects even with a closed mouth.

Is It Bad to Sleep With Your Mouth Open?

Sleeping with mouth open has a number of fatal side effects. If one continues to breathe through his/her mouth, it may lead to certain health and medical problems, which may include:

  • Fewer amounts of oxygen are delivered to the body while breathing through the mouth, rather than nose
  • The filtration system in the mouth is not as well designed as in case of nose
  • Although the saliva keeps washing away bacteria, constant mouth breathing will dry your mouth up. This results in absence of filtration medium making your body more prone to infections
  • Gingivitis and tooth decay due to bacteria
  • Development of a cough because of constantly drying up
  • Development of sleep disorders including sleep apnea
  • Hypertension
  • Increased heart rate
  • An asthmatic cough
  • Altered facial structure

In children, breathing through the mouth can also lead to:

  • Lack of sleep
  • Stunted growth
  • Lack of focus and interest
  • Detrimental oral health

Now we shall discuss a few ways- How To Keep Mouth Closed While Sleeping:


Our brain is a very powerful organ. With determination and constant reminders, it can be made to work in miraculous ways. Throughout the day, keep reminding yourself to breathe through your nose forcefully. Set up hourly reminders, reminders on your working surface, and sticky notes everywhere around you to constantly remind you of how serious this is. Hopefully, your brain will adapt to these constant reminders very soon and you will figure out a unique way of how to train yourself to sleep with your mouth closed


Try to keep your nose clean at all times throughout the day. Make it a habit to clean your nose thoroughly with water especially before going to bed. 


In case you feel your nose is getting blocked at night, use a saline spray to clear it up.


Try to prop yourself up a bit while you sleep. This provides an easy passage to your airway for the flow of air. It also helps to relieve congestion. 


Sleeping on your back increases the chances of mouth breathing because it makes your mouth open while you sleep. It is best to sleep on your side while you’re propped up. This will help you breathe better through your nose.


This comes in handy, especially for kids. Use a cap with a soft material that has a strap around the chin. Make sure the material does not hurt the skin of your toddler and the cap is not too warm or too thick, otherwise the baby will remain fussy through his sleep. Allow the child to cover his chin with the strap while he sleeps. This will hold the lower jaw steady and the kid will have difficulty in mouth breathing. As a result, he might try to breathe through the nose


Try to keep yourself well hydrated throughout the day. This will help in retaining moisture in your mouth. It is recommended to drink at least 3 liters of water every day.


While asleep, if you feel your mouth getting dried up, get up and sip on some water. This will help you retain moisture in your mouth and prevent you from complications of oral breathing.


There might be different reasons for mouth breathing. You need to determine your cause so that it could be treated accordingly. A few causes may be:

  • You might have developed a habit over the time
  • You might have enlarged tonsils that make you uneasy while breathing through nose
  • Your dental structure might be damaged causing trouble in closing your mouth while you sleep
  • Nasal blockage, due to any reason
  • Due to the disease SLEEP APNEA. Sleep apnea means the inability of the body to breathe while sleeping. This could be of two types:

    Obstructive sleep apnea: this occurs due to blockage of air passages, usually when the soft tissue in the throat collapses while sleeping

    Central sleep apnea: this happens when the brain is unable to signal the muscles responsible for respiration to breathe.

    As a result of sleep apnea, patients may suffer from lack of interest in routine activities, general fatigue, headaches, hypertension, diabetes and many other diseases.

Try to keep your surroundings as neat as possible. Remove any potential allergens. This includes pets. Remove carpets and rugs and do not use furry blankets, coats or hats. Try to dust your rooms every day. Avoid going out into floral gardens, in the case of pollen energy.

A mouth guard is another device that helps you to breathe nasally. It is worn on your chin in order to block your jaw. As a result, your mouth remains shut so you cannot snore and ultimately, you’re forced to breathe through your nose.


It is always better to get yourself checked. It might happen, although the occurrence is very less, that your oral breathing habit could be because of the damaged jaw or tooth structure. Visiting a dentist will rule out the chances of this factor


If possible, ask someone to watch over you while you sleep and gently push your lower jaw up to close your mouth, in case you start breathing through your mouth. If you continue to do so, your guardian angel should wake you up. Parents should do this for small children.


Snoring also leads to oral breathing. If you’re a frequent snorer, take necessary steps such as using a snore belt to finish off snoring. It could also be an indication that you have Sleep Apnea. You should never take it lightly and should immediately have a Sleep Study Test.


Myofunctional therapists are skilled in helping people gain command over their muscles. If the cause of your snoring is due to muscle dystrophy, seeing a Myofunctional Therapist can always help.
