The Hidden Breathing Problem That Can Look Like ADHD

Your child’s behaviour problems might start with the way they breathe.

Dentist Dr Jason Leung joins Justin to explain why mouth breathing can affect sleep, concentration, emotional regulation and behaviour, and why some of the signs can look remarkably similar to ADHD.

They unpack the clues parents often miss, including snoring, teeth grinding, waking tired and breathing through an open mouth. Jason also explains why jumping straight to mouth taping, expanders or other devices may not fix the underlying problem, and what parents should check first.

KEY POINTS

• How mouth breathing can interfere with quality sleep
• Why poor sleep can show up as hyperactivity, poor concentration, grumpiness and meltdowns
• The possible connection between sleep-disordered breathing and ADHD-like behaviour
• Signs to watch for, including snoring and teeth grinding
• Why children need to be able to breathe freely through their nose before trying to change their breathing habits
• The role of the tongue, lips and diaphragm in healthy breathing
• Why mouth tape and airway devices aren't always the answer
• When Jason recommends having a child’s breathing and oral function assessed

ACTION STEPS FOR PARENTS

• Notice how your child breathes when they’re relaxed and asleep.
• Look for regular mouth breathing, snoring or teeth grinding.
• Pay attention to whether they wake tired, grumpy or poorly regulated despite getting enough hours in bed.
• Don’t use mouth tape if your child cannot comfortably breathe through their nose.
• If you’re concerned, seek professional assessment of their airway, breathing and oral function.
