How You Breathe Matters

When you breathe through your nose, your body produces nitric oxide - a powerful molecule that helps support oxygen flow, circulation, and immune function. 

When breathing shifts to the mouth, nitric oxide production drops. 

Over time, this can contribute to:

  • Poor sleep quality
  • Increased inflammation
  • Dry Mouth and higher cavity risk 
  • Reduced oxygen efficiency

In biological dentistry, we pay attention to how you breathe - not just your teeth. 

Because something as simple as nasal breathing can impact your entire system. 

If you're unsure how you're breathing, ask about a screening at your next biological hygiene visit!
