1. It’s Often Temporary

Colds, allergies, or seasonal flu can block nasal passages, forcing mouth breathing. In children, this habit may fade as their immune system strengthens and nasal passages grow.

2. Enlarged Tonsils and Adenoids Can Be the Cause

If a child frequently sleeps with their mouth open, enlarged tonsils or adenoids could be limiting airflow. In many cases, a doctor’s check-up can determine if treatment is needed.

3. It’s Not Just About Comfort

Mouth breathing can dry out the mouth, leading to gum issues, bad breath, and even more cavities. It also affects sleep quality, making mornings groggier.

4. Some Cases Need Medical Attention

If mouth breathing is paired with snoring or gasping, it may be sleep apnea — a condition that should be addressed promptly to protect long-term health.

5. Simple Steps Can Help

• Keep rooms dust-free to reduce allergies.
• Use a humidifier at night to prevent dryness.
• Encourage nasal breathing exercises for older kids.
