Evaluation of an Experimental Mouth Rinse Device for Relieving Dentinal Hypersensitivity

This study is for people with sensitive teeth and involves going to the dentist for 4 visits over 6 weeks. At each visit the dentist will look at the mouth, teeth, tongue and gums of subjects, and check for sensitive teeth. During the first 2 weeks, participants will brush their teeth two times a day with the fluoride toothpaste provided. Then, if they qualify to continue in the study, participants will be assigned to a treatment group. All the groups will get toothpaste currently sold on the market, and one group will get a mouthwash with an experimental ingredient to use as well. Subjects will have an equal chance of being assigned to any one of the three groups. For the next 4 weeks, subjects will use their assigned products according to the directions provided. At Visit 1 subjects will be supervised while they brush their teeth to ensure they understand the directions. They will also have supervised use of the product at Visit 2. We will see if the mouthwash helps to reduce tooth sensitivity during the study.
