Course Description:

Mouth breathing doesn’t look good, but more importantly, it leads to severe oral and general health problems. The physiology of breathing explains why less oxygen is absorbed with mouth breathing compared to nose breathing. Mouth breathing, also called sleep-disordered breathing, is implicated in sleep apnea, attention deficit disorder, and daytime fatigue. Ankyloglossia, infant feeding, pacifier use, thumb sucking, and tongue rest position may all influence mouth breathing. Three essential actions taken by dental professionals will help switch mouth breathers back to nasal breathing.

Learning Objectives:

  • Understand oxygen absorption differences between nasal and mouth breathing.
  • Describe the systemic implications of mouth breathing.
  • Explain how mouth breathing influences facial development in children.
  • Describe the benefits of xylitol for enhanced nasal breathing.
