How Mouth Breathing Affects Your Child’s Development (And What You Can Do About It)

Mouth breathing may seem harmless, but it can lead to serious problems in your child’s development. From jaw alignment to sleep quality, this habit affects more than just how your child breathes—it influences how they grow.

At Myofunctional Therapy Surrey, we help families across Surrey and the Lower Mainland identify and treat oral habits like mouth breathing before they create long-term issues.

What Is Mouth Breathing—and Why Is It a Problem?

Mouth breathing occurs when a child breathes through the mouth instead of the nose. It’s often due to nasal blockages, allergies, or poor tongue posture. Over time, this habit can lead to:

  • Facial elongation
  • Narrow jaw and crowded teeth
  • Speech difficulties
  • Snoring or poor sleep
  • Focus and behavioural concerns

The Link Between Mouth Breathing and Development

When children breathe through their mouths:

  • The tongue rests low instead of supporting the palate
  • Oxygen intake may be reduced
  • Sleep becomes disrupted
  • Growth patterns in the face and jaw can shift

This affects everything from academic performance to self-esteem.
