Brief Summary

This is a 30 day randomized, parallel comparative trial where participants with tooth shade of C2 or darker will be assigned to one of five groups.

• Be in good general health, as determined by the investigator/designee based on a review of the health history/update for participation in the study.
• Have at least 4 gradable maxillary anterior teeth ( canine to canine) with a Vita Shade average score of C2 or darker.
