How Does Mouth-Breathing Affect Children? January 23, 2020

How Does Mouth-Breathing Affect Children?, Ewa, Hawaii

While it’s sometimes acceptable for a child to breathe through their mouth, such as when congested with a cold, consistent mouth-breathing can lead to a whole host of issues. Learn more about why mouth-breathing is detrimental and how a pediatric dentist can help with solutions.

Causes of Mouth-Breathing

Mouth-breathing is most often caused by nasal obstructions, which make it more difficult for air to pass through. It’s common among kids with allergies, as inhaling allergens causes nasal airways to swell and become congested.

Oral structures, such as tonsils and adenoids, can also become enlarged, sometimes due to infections.

Additionally, problems with the way the nose or jaw are shaped can affect breathing patterns. 

How It Affects a Child’s Health

Mouth-breathing can even affect a child’s sleep. A child with this problem may appear lazy and unmotivated due to a lack of sleep, which can cause disciplinary issues. 

How It Can Be Treated

Finding the underlying cause is the first step to treatment. If the issue is allergies, medication like antihistamines and nasal sprays can reduce nasal swelling and congestion. Swollen oral structures, including tonsils, can be surgically removed if the problem is persistent.
