10 Reasons Why Mouth Breathing is Bad For You

Dry Mouth

Mouth breathing can leave the mouth dry due to a lack of saliva, which can negatively impact oral health, leading to discomfort and bad breath.

Increased Risk of Cavities

Saliva acts as a buffer that protects your teeth. A dry mouth from mouth breathing has less protection, increasing the chance of cavities.

Bad Breath

Also known as halitosis, bad breath is a common complaint among those who breathe through their mouth. This condition can be worsened by the dry environment created in the mouth during mouth breathing.


Mouth breathing at night can lead to snoring, disturbing sleep patterns, and affecting the individual and their partner.

Sleep Disorders

It is associated with sleep disorders that affect daily life, including sleep apnea, which can have significant health implications if left untreated.

Gum Disease

A dry mouth from breathing through the mouth can lead to gum disease. Gum disease can progress to more severe conditions if not addressed properly.


Breathing through the mouth can dry out the airways, leading to a feeling of hoarseness or a sore throat, especially evident in the morning.

Chronic Fatigue

Mouth breathing can lead to poor sleep quality, resulting in waking up tired and irritable, and may contribute to chronic fatigue over time.

Brain Fog

Impaired sleep quality from mouth breathing can also lead to difficulties with concentration and memory, often called brain fog.

Compromised Facial Development

In children, chronic mouth breathing can affect facial development, leading to long-term issues with the teeth and jaw alignment.
