Summary

This study is for people with sensitive teeth and involves going to the dentist for 4 visits over 6 weeks. During the first 2 weeks, you will just brush your teeth two times a day with the fluoride toothpaste provided. Then you will be assigned to a group if you qualify to continue in the study. All groups will get a marketed toothpaste and one group will also get a mouthwash with an experimental ingredient. You will have an equal chance of being assigned to any one of the three groups. For the next 4 weeks, you will brush with your assigned toothpaste and rinse with your assigned mouthwash if assigned to the mouthwash group. A dentist will look at your mouth, teeth, tongue and gums and check for sensitive teeth. The investigators will see if the mouthwash helps to reduce tooth sensitivity during the study.

Eligibility Criteria

Inclusion Criteria

  • Males and females at least 18 years of age in good general and oral health without any known allergy to commercial dental products or cosmetics.

  • Willingness to use the assigned products according to instructions, availability for appointments, and likelihood of completing the clinical trial.
  • The appropriate number and location of eligible teeth, based on protocol-defined standards.
  • Adequate oral hygiene (i.e., brush teeth daily and exhibit no signs of oral neglect).

Exclusion Criteria

  • Any medical or dental history or condition, or use of any medication or drug, that per protocol or in the opinion of the investigator might compromise subject comfort or safety, or the analysis of study results.
  • Volunteers who have been using any of the following within protocol-defined timeframes:
  • home-care bleaching, whitening products or professional bleaching treatment
  • desensitizing agents whether prescribed or over-the-counter
  • sensitivity toothpastes, mouthwash or oral care products used for the treatment of dentinal hypersensitivity
  • Women who are pregnant, nursing or plan to become pregnant during the course of the study.
