• agree to return for scheduled visits and follow all study procedures
• have dentinal hypersensitivity with at least one tooth with a Schiff sensitivity score of at least 1 in response to the examiner applied cold water challenge

Exclusion Criteria:

• severe periodontal disease, as characterized by purulent exudate, generalized mobility, and/or severe recession
• active treatment for periodontitis
