Dry mouth, medically known as xerostomia, is more than just an uncomfortable feeling. It is a signal that your body’s natural moisture balance, especially in your airway, is not functioning optimally.
What is Dry Mouth?
Dry mouth occurs when your salivary glands do not produce enough saliva to keep your mouth comfortably moist.
You may notice:
-
A sticky or parched feeling in the mouth
-
Difficulty swallowing or speaking
-
Bad breath
-
Cracked lips or a dry throat on waking
It is commonly linked to mouth breathing, dehydration, air-conditioning, medications, or nasal congestion that forces airflow through the mouth rather than the nose.
Why Is Dry Mouth a Problem?
Saliva plays a critical role in protecting oral and respiratory health. When saliva is reduced:
-
Bacteria multiply more easily, increasing the risk of cavities and gum disease
-
Bad breath becomes more persistent
-
Sleep quality suffers, especially if dry mouth is caused by overnight mouth breathing
-
The throat and airways become more irritated, leading to discomfort and recurrent inflammation
In many cases, dry mouth is not just an oral issue it is a breathing issue.
How Nadu Helps Address Dry Mouth at Its Source
At Nadu, we focus on correcting the root cause, not just masking the symptom.
Dry mouth is often a downstream effect of impaired nasal breathing. When nasal airflow is restricted, the body compensates by breathing through the mouth leading to moisture loss and dryness.

Nadu Mouth Tape – This product gently encourages nasal breathing by keeping the mouth closed overnight. By reducing mouth breathing, the primary driver of dry mouth, it can help you wake up without the uncomfortable dryness and sore throat common after nights of breathing through the mouth. It is hypoallergenic, medical-grade tape intended for habitual use at bedtime and can also help with snoring and sleep quality improvement.
How It Helps with Dry Mouth
-
Mouth tape reduces overnight mouth breathing, which is one of the most common causes of waking with a dry mouth.
- By supporting nasal breathing, it helps preserve saliva moisture and allows the natural humidification function of the nasal airway to protect oral tissues.
Nadu products are designed to:
-
Support optimal nasal airflow, making nose breathing easier day and night
-
Reduce reliance on mouth breathing, especially during sleep
-
Promote natural humidification and filtration of air, which only the nose can provide
-
Improve overnight breathing patterns, helping you wake without dryness or irritation
By restoring nasal function, Nadu helps the body return to its natural breathing pathway allowing moisture balance to normalise without artificial sprays or constant hydration.
