NCT ID NCT06365047
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether an arginine-containing toothpaste can change the acidity of saliva in people with dry mouth caused by medications. Seventy adults will use either the arginine toothpaste or a regular fluoride toothpaste for 12 weeks. Researchers will measure saliva pH and mouth bacteria to see if the toothpaste helps balance the oral environment.

Active substance
8% arginine toothpaste
What this could lead to
If it works, this could point toward a simple, daily way to ease dry mouth discomfort for people taking multiple medications.
What could go wrong
This is a small, early-phase trial focused on mouth chemistry, not symptoms directly. The toothpaste may not meaningfully improve dryness or quality of life.
