A Study of the Relief of Tooth Sensitivity of an Experimental Mouthrinse Device

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.
