Sensitivity, Tooth
Conditions
Brief summary
The objective of this clinical investigation is to assess the efficacy of a toothpaste containing 8% arginine (Colgate-Palmolive Company, New York, NY, USA) as compared to a commercially available non-desensitizing toothpaste (Colgate Cavity Protection Toothpaste, Colgate-Palmolive Company, New York, NY, USA) in the reduction of dentinal hypersensitivity over an eight (8) week period.
Interventions
Cover the entire length of bristled head with toothpaste. Brush your teeth twice daily (morning and evening) for one (1) minute each time. For investigational use only by the study participant. Not for Sale.
