Why Mouth Breathing Increases During Winter (And How to Stop It)

Introduction

Mouth breathing becomes more common in winter, especially due to allergies, dry air, and seasonal colds. However, breathing through the mouth instead of the nose can negatively impact oral health. At Langley Dental, we help patients understand the consequences of mouth breathing and how to correct it.

How Mouth Breathing Affects Oral Health

  • Dry mouth: Reduced saliva creates a high-risk environment for cavities and gum disease.
  • Bad breath: Bacterial growth increases without adequate moisture.
  • Gum inflammation: Chronic dryness leads to irritation and recession.
  • Crooked teeth in children: Mouth breathing can affect facial development over time.

Causes of Mouth Breathing

  • Nasal congestion from cold or flu.
  • Seasonal allergies.
  • Deviated septum
  • Enlarged tonsils or adenoids
  • Habitual mouth breathing

How to Reduce Mouth Breathing

  • Use a humidifier to moisten indoor air.
  • Treat nasal congestion with doctor-approved remedies.
  • Practice nose-breathing exercises.
  • Stay well-hydrated.
  • Schedule a dental evaluation if dry mouth symptoms persist.

Mouth breathing is more than a seasonal inconvenience—it can significantly affect your dental health. If you’re experiencing dry mouth or chronic mouth breathing this winter, book a visit at Langley Dental so we can help protect your smile.
