During the first two weeks of the study, subjects will be instructed to brush their teeth for one minute in their usual manner, twice daily, using the provided standard fluoride toothpaste. Subjects will return for the Baseline exam and, upon qualification with entry criteria, will be assigned to one of three treatment groups. Qualified subjects will be instructed to brush their teeth two times daily for one minute in their usual manner using the provided toothpaste (standard fluoride toothpaste or 5% potassium nitrate toothpaste).
