CRYSTAL BLOCK™ TECHNOLOGY

Crystals build with every rinse to provide deep, stable, comprehensive tubule occlusion1-3

LISTERINE® Clinical Solutions Sensitive Teeth Mouthwash with CRYSTAL BLOCK™ Technology provides daily repair of damage by creating a powerful barrier for continuous sensitivity protection. It provides 24-hour protection for sensitive teeth,* reaching virtually 100% of sensitive areas.^1,3 Most oral care sensitivity products either numb the nerve endings or create a thin protective layer on the exposed dentin.^3,4

LISTERINE® Clinical Solutions Sensitive Teeth Mouthwash blocks open tubules by depositing stable crystals both on the surface of the dentin and deep inside the tubules.^1,3

MINIMALLY AFFECTED BY ACID OR MECHANICAL METHODS; TUBULE OCCLUSIONS REMAIN RESISTANT^1,3

Provides tough, durable occlusion, unlike competitive occlusive toothpaste^1,3

- Achieves 99% occlusion after 12 rinses³

- Maintains 92% tubule blockage even after challenge¹*

- Occlusion from competitive toothpastes erodes by as much as 50% after mechanical and acid challenge^1,3†
