“In clinical testing, Sonu relieved nasal congestion twice as well as placebo, with 81% of users responding. When patients can breathe through their nose at night, everything downstream improves.”

Your toothbrush works for 2 minutes.
Your nose works all night.
What happens to a freshly brushed mouth over 8 hours depends on one thing: which airway you sleep with.
Bedtime — you brush
A 2-minute power brush clears roughly 60–85% of plaque. Both sleepers start the night nearly clean, with only ~15–30% residual.
Nasal breather
- Saliva keeps flowing (~0.3 mL/min)
- Bicarbonate & IgA buffer pathogens
- Bacteria grow slowly, linearly
pH ~7.0
neutral, enamel protected
Mouth breather
- Airflow evaporates saliva, dries tissue
- Acid-tolerant pathogens grow exponentially
- Dense, sticky, acidic plaque forms
pH < 5.5

By morning, only one of them kept last night’s brushing.
Nose breatherSoft, thin morning biofilm on a protected enamel surface.
Mouth breatherRapid biofilm regrowth erases much of the toothbrush’s work.
Sonu clears the path to nasal breathing. Fifteen minutes of FDA-cleared acoustic resonance before bed relieves congestion — drug-free — so your nose, not your mouth, handles the night shift.
