Why Do People Sleep with Their Mouth Open?
Mouth breathing during sleep is more common than many realize. Often, it occurs when nasal airflow is blocked due to colds, seasonal allergies, or inflamed tonsils. For many children, enlarged adenoids can make nose breathing difficult, and the problem may improve naturally as they grow.
Medical Conditions That May Be Involved
- Deviated Nasal Septum: A misaligned nasal wall can cause chronic congestion, forcing mouth breathing. In severe cases, surgery may be advised.
- Sleep Apnea: If mouth breathing is paired with loud snoring or pauses in breathing, it may signal obstructive sleep apnea, a potentially serious condition requiring medical attention.
Impact on Oral Health & Sleep
Breathing through the mouth can dry out oral tissues, reducing saliva production. This creates a higher risk of gum irritation, bad breath, and tooth decay. It can also interfere with deep, restorative sleep, leading to daytime fatigue.
When to Consult a Doctor
Persistent symptoms such as a dry throat, morning headaches, or frequent nighttime awakenings should not be ignored. Early evaluation by an ENT or sleep specialist can prevent complications and improve quality of life.
