Females of childbearing potential must be using a medically acceptable method of birth control for at least one month prior to Visit 1 and agree to continue using this method during their participation in the clinical trial. Medically acceptable forms of birth control that may be used by the subject and/or his/her partner include: * Double barrier method (condoms, diaphragm or cervical cap with spermicide), * Hormonal prescription contraceptives (i.e., oral, injectable, implanted, patch or vaginal ring hormone therapy) * Intrauterine device (IUD) * Surgical sterilization (e.g., vasectomy that has been confirmed effective by sperm count check, tubal ligation, hysterectomy and/or bilateral oophorectomy) * Abstinence 8. A minimum of 16 uncrowned teeth; 9. At Screening (Visit 1) and before brushing with the assigned study product at Baseline (Visit 2), subjects must provide 2 samples of mouth air, which must have a mean hydrogen sulfide concentration greater than 200ppb. At screening and baseline (pre-brushing), the two samples of mouth air must have a ≤ 500ppb difference in hydrogen sulfide values; 10. At Baseline (Visit 2), before brushing with assigned dentifrice, subjects must provide a breath sample with a mean organoleptic score ≥3.5 across judges; 11.

Planned surgery during the trial period, 6 months prior to clinic visit 1 or 30 days after the end of study period; 9. Has a compromised immune system; 10. Has any acute or chronic, medical or psychiatric conditions) that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgement of the medically qualified investigator, would make the subject inappropriate for entry in this study; 11. Significant, unstable or uncontrolled medical condition which may interfere with subject's participation in the study, at the discretion of the Investigator; and 12. Subjects who are related to those persons involved directly or indirectly with the conduct of this study (i.e., principal Investigator, sub-investigators, study coordinators, other site personnel, employees of Johnson \& Johnson (J\&J) subsidiaries, contractors of J\&J, and the families of each).
