How does posture affect breathing and crooked teeth in children?

Posture has a direct impact on how children breathe, especially during growth and development. Here’s how:

We Have a Solution for You!

1. Airway and Breathing Efficiency

  1. Forward head posture (common when kids look down at devices) narrows the upper airway. This makes breathing less efficient and may encourage mouth breathing.
  2. Slouched sitting compresses the chest and diaphragm, limiting lung expansion and reducing oxygen intake

2. Mouth Breathing and Facial Growth

  • Poor posture often goes hand in hand with open-mouth posture, which can change tongue position.
  • If the tongue rests low instead of on the palate, it can affect jaw growth, leading to narrow arches, crowded teeth, and higher risk of sleep-disordered breathing.

3. Sleep and Snoring

  • A child with poor posture is more likely to have airway obstruction during sleep, contributing to snoring or sleep apnea.
  • This can affect concentration, behavior, and growth due to disrupted oxygen supply at night.

4. Neuromuscular

  • Good posture supports the balance of muscles around the head, neck, and jaw.
  • Poor posture strains these muscles, which can affect not only breathing but also swallowing and speech development.

✅ Practical tips for parents:

  1. Encourage children to sit upright, with feet flat on the floor.
  2. Promote shoes with « barefoot Â» structure..
  3. Promote activities that strengthen core muscles (swimming, climbing, posture games).
  4. Limit screen time and adjust screen height to reduce forward head posture.
  5. Ensure nasal breathing and check with a pediatric dentist/ENT if mouth breathing persists.
