Why mouth breathing is bad for your health

Mouth breathing is bad for your health as it results in an increased susceptibility to:

  • Colds
  • Tonsillitis
  • Coughs
  • Chest infections

This is because mouth breathing bypasses your body’s main air filtration system (the nose!).  The nose acts as an ‘air-conditioner’ that filters & humidifies the air we breathe.

When you breathe through your mouth you drag large volumes of cold, unfiltered air containing viral & bacterial matter directly into the sensitive lung passages.  This increases your chance of developing colds, coughs or chest infections.

In addition, mouth breathing subjects the tonsils to heavy air filtration duties which they are not designed to undertake.  In most cases the tonsils will become swollen & inflamed as a result.

John Flutter Dental offer “Breathing Retraining Programmes” for children and adults.

How breathing influences your teeth

Did you know that people who breathe through their mouth are more likely to have crooked teeth?

The normal, healthy human function is to breathe through the nose.  Not only is this better for air filtration and general health but it also plays an important role in the development of your teeth and jaws.

Nasal breathing allows the tongue to rest in the roof of the mouth, the muscle forces from the tongue push against the palate to develop correct arch shape and size.  Ideally there should be enough room for the tongue to fit comfortably in the upper arch & therefore the teeth will be well aligned.

This natural process is disrupted when ‘mouth breathing’ sets in as the tongue is no longer sitting in the roof of the mouth; the upper arch loses the support essential for normal development – it becomes small and narrow therefore the teeth become crooked.

Lower arch development is guided by the upper arch formation.  If the upper arch is small and narrow the lower arch will follow this form as it “trapped” inside the upper jaw.

Establishing nasal breathing at an early age is essential.  John Flutter Dental provides ‘Breathing Retraining Programmes’ to help children establish nasal breathing and an improved breathing pattern.

What is myofunctional orthodontics?

Myofunctional orthodontics treats the underlying cause of irregular teeth and does not require the use of traditional “Braces”.

Myofunctional therapy can be used as an early intervention method for young children in order to prevent the need for more extensive treatment such as arch expansion or braces later on.a

If the child has a more severe pattern or is of an older age, Myofunctional therapy can also be used in conjunction with arch expansion to enhance the effectiveness during treatment and ensure stable results after treatment.

Breathing Through Your Mouth Will Lead to Crooked Teeth

Orthodontics Can Straighten Your Teeth, But If You’re Looking for a More Long-Term Solution John Flutter Dental Can Help You

Not only does mouth breathing lead to crooked teeth, it can also increase the risk of tooth decay as well as make you more susceptible to illness. This is because if you breathe through your mouth, you are bypassing your body’s natural filtration system. The risk of tooth decay arises because breathing through your mouth dries out your teeth. This makes it harder for saliva to fight off bacteria that slowly demineralises the tooth surface.

Breathing through the nose is how you are supposed to breathe. When you breathe through your nose, your body filters the air before it gets to your lungs and your tongue rests on the roof of your mouth. This is important because having your tongue resting in the roof of the mouth plays a part in having the correct jaw size. With the correct jaw size there is less chance of needing to have teeth extracted.

Did You Know That Mouth Breathing Can Lead To Sleep Apnoea?

Mouth breathing can lead to sleep apnoea because of the effect breathing through your mouth has on your jaw. Teeth usually become crooked because the jaws aren’t large enough for the teeth. But did you know that every child’s face has the growth potential to match its own set of teeth?

Every child has the genetic potential to develop straight teeth. One of the deciding factors is how they breathe. If your child is a mouth breather, not only will they develop crooked teeth but they also run the risk of other health problems.

One of these other health problems is sleep apnoea; which is typically characterised by pauses in breathing or irregular breathing during sleep.  Sleep apnoea occurs when the walls of the throat come together during sleep, breathing stops and it takes time for the brain to realise the drop in oxygen levels and wakes the body up. This can happen hundreds of times a night, leaving you feeling fatigued in the morning—almost as though you didn’t get any sleep. By learning to breathe properly and to have proper posture, you can avoid health problems like crooked teeth and sleep apnoea.

The Relation of Mouth Breathing to Sleep Apnoea

The reason mouth breathing can cause sleep apnoea is because of what mouth breathing does to your jaw. When you breathe through your nose, your tongue is on the roof of your mouth keeping your jaw forward. When you breathe through your mouth, the tongue is not resting in the roof of your mouth exerting pressure, so the jaw moves back.

When you sleep, because of where the jaw is now positioned, it can block off the airway making it hard to breathe and resulting in sleep apnoea.

At John Flutter Dental in Brisbane we offer a number of treatment programs to help both children and adults learn to breathe through their nose. By doing this you can actively reduce the risk of sleep apnoea and other mouth breathing related problems.
