Are you worried that mouth breathing might be the reason for your bad breath? If so, don’t worry – you are not alone. Mouth breathing is a common problem that affects millions of people around the world. In this article, we will discuss the causes of mouth breathing, the consequences and some common ways to treat it.

Mouth Breathing is when you can't breathe through your nose

1: What Is Mouth Breathing And Why Does It Cause Bad Breath?

Mouth breathing is the act of breathing through your mouth instead of your nose, usually due to nasal blockage.

Mouth breathing can cause bad breath because it leads to dry mouth and accumulation of bacteria (you can more about dry mouth and bad breath here). Mouth breathing also causes increased congestion in the throat, which can lead to a dry mouth and other oral health problems. 

2: Why Nose breathing is more beneficial than mouth breathing and can reduce bad breath

Nose breathing


Breathing through your nose can help filter out dust and allergens, boost your oxygen uptake, and humidify the air you breathe in. Mouth breathing, on the other hand, can dry out your mouth. This may increase your risk of bad breath and other health conditions.

3: The Causes and Consequences Of Mouth Breathing include bad breath

Mouth breathing is a common problem that affects millions of people. It is often caused by enlarged adenoids, enlarged tonsils, nasal congestion or respiratory problems such as asthma, nasal allergies, nasal polyps, colds or chronic sinusitis.  

Allergies can block nose and cause mouth breathing

If you are a mouth breather you may experience snoring and sleep disorders (ie sleep apnea), hoarseness, feeling tired during the day, changes in the structure of one's faces and dental problem such as malocclusion, dry mouth, bad breath, gum disease or tooth decay.

4: How To Stop Mouth Breathing

While mouth breathing is a common problem and can be experienced temporarily during allergy or cold season, if it's become a norm you should talk to your healthcare provider about potential treatments.

If mouth breathing is related to sleeping issues, your doctor may ask you to lose excess weight, and reduce or avoid drinking alcohol, or CPAP therapy for more serious cases.

Common surgeries that may be recommended to enable people to breathe through their nose are adenoidectomy, tonsillectomy, septoplasty.

If your mouth breathing is due to cold or allergies, you can also take medications to treat colds, congestions, sinus infections and allergies to help reduce nasal blockage.
