Toothpaste showdown: new study pits three formulas against sensitive teeth

NCT ID NCT07664592

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This Phase 3 trial compares three different toothpaste technologies for relieving tooth sensitivity (dentin hypersensitivity). About 132 adults with sensitive teeth will brush with one of three toothpastes: one with 8% arginine, one with 8% arginine plus zinc, or one with 5% calcium sodium phosphosilicate. Researchers will measure how well each paste reduces pain from air and touch stimuli right after brushing and over two weeks.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

toothpaste containing 8% arginine, 8% arginine with zinc phosphate, or 5% calcium sodium phosphosilicate

What this could lead to

If successful, this study could show which toothpaste technology works best for quick and lasting relief from tooth sensitivity.

What could go wrong

This is a short-term trial (2 weeks) with only 132 participants, so results may not apply to everyone. Tooth sensitivity can have many causes, and these pastes may not work for all types.
