Tooth Sensitivity Relief by Two Mouthrinses

Completed · Not applicable

Conditions studied: Dentin Sensitivity

In brief

This study is for people with sensitive teeth and involves going to the dentist for 6 visits over 8 weeks. During the first 2 weeks, everyone will just brush their teeth two times a day with the fluoride toothpaste provided. Then you will be assigned to a mouthwash group if you qualify to continue in the study. Two groups will get mouthwash with a certain amount of an experimental ingredient and one group will get a mouthwash with no experimental ingredients. You will have an equal chance of being assigned to any one of the three groups. For the next 6 weeks, you will rinse with your assigned mouthwash after brushing. 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.
