5. Able to read and understand the local language (subject is capable of reading the documents).

6. Generally, in good health based on medical history reported by the subject.

7. In good oral health with adequate oral hygiene (i.e. brush teeth daily and exhibit no signs of gross oral neglect).

8. Negative pregnancy urine tests (females of child-bearing potential only):

   • For females: Postmenopausal state (i.e. at least 1 year without menses without an alternative medical condition prior to the first study IP administration) or premenopausal/perimenopausal state with an effective means of contraception.
   • For males: No pregnant or lactating spouse or partner at screening and willingness to utilize an acceptable form of birth control with spouse or any potential partner during the study and for 30 days thereafter.

9. 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

10. A minimum of 16 uncrowned teeth.

11. Absence of significant oral soft tissue pathology, periodontitis and active dental caries, based on a visual examination and at the discretion of the Investigator.

12. Absence of partial dentures, dentures, orthodontic bands, fixed retainers, removable orthodontic appliances.

Exclusion Criteria:

1. Diagnosed with Xerostomia.

2. Suspected alcohol or substance abuse at the discretion of the Investigator (e.g., amphetamines, benzodiazepines, cocaine, marijuana, opiates).

3. Known sensitivity, allergy or contraindications to any investigational product ingredient, oral care products and auxiliary supplies provided for the study.

4. Self-reported smokeless tobacco user including snuff, chewing tobacco, vaping and e-cigarette usage.

5. Females who are self-reported to be pregnant, planning to become pregnant or breastfeeding during the study.

6. Participation in any clinical study investigation within 30 days of Screening visit (Visit 1).

7. Planned surgery during the trial period, 6 months prior to clinic visit 1 or 30 days after the end of study period.

8. Has a compromised immune system, in the judgement of the medically qualified investigator.

9. 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;

10. Significant, unstable or uncontrolled medical condition which may interfere with subject's participation in the study, at the discretion of the Investigator.

11. Has self-reported Type 1 or Type 2 diabetes or is taking insulin or another anti-diabetic medication;

12. Is taking a medication that would mask an Adverse Event (AE) or confound the study results, including:

    • Immunosuppressive or steroidal drugs within 2 months before Visit 1.*
    • Non-steroidal anti-inflammatory drugs within 5 days before Visit 1.
    • Antihistamines within 2 weeks before Visit 1.

13. 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 Kenvue Brands LLC/Johnson & Johnson (J&J) subsidiaries, contractors of Kenvue/J&J, and the families of each).
