Teeth that are grossly carious, extensively restored, orthodontically banded, abutments, exhibiting severe generalized cervical and/or enamel abrasion, or third molars will not be included in the tooth count Absence of significant oral soft tissue pathology, excluding plaque-induced gingivitis, based on a visual examination and at the discretion of the Investigator Absence of advanced periodontitis based on a clinical examination and discretion of the dental examiner Absence of fixed or removable orthodontic appliance or removable partial dentures Exclusion Criteria: History of significant adverse effects, including sensitivities or suspected allergies, following use of oral hygiene products such as toothpastes, mouthwashes, and red food dye Dental prophylaxis within four weeks prior to Baseline visit History of medical conditions requiring prophylactic antibiotic coverage prior to invasive dental procedures; Use of antibiotics, anti-inflammatory or anticoagulant therapy, phenytoin sodium or diphenylhydantoin, cyclosporin A, immunostimulants/ immunomodulators during the clinical trial or within the one month prior to the Baseline exam. Intermittent use of certain anti-inflammatory medication (ibuprofen, Aspirin); oral steroids and calcium channel blockers are acceptable at the discretion of the investigator Use of chemotherapeutic anti-plaque/anti-gingivitis products such as triclosan, essential oils, cetylpyridinium chloride, sodium fluoride with cetylpyridinium chloride (CPC), stannous fluoride, zinc or chlorhexidine digluconate containing mouthwashes and toothpastes within the four weeks prior to the Baseline exam Known allergy or sensitivity or history of significant adverse effects to any of the investigational product and/or product ingredients (or other ingredients in the products) specifically Cinnamyl Alcohol, Benzyl Alcohol, Citral, Citronellol, Linalool, and Limonene Self-reported pregnancy or lactation (this criterion is due to oral tissue changes related to pregnancy and nursing which can affect interpretation of clinical trial results) Self-reported smokeless tobacco user including snuff, chewing tobacco, vaping, and e-cigarette usage Males with a pregnant partner or a partner who is currently trying to become pregnant Suspected alcohol or substance abuse (for example, amphetamines, benzodiazepines, cocaine, marijuana, opiates) Significant medical or oral condition which may interfere with a participant's participation in the clinical trial, including cancer, chronic kidney disease, chronic obstructive pulmonary disease (COPD), immunocompromised state (weakened immune system) from solid organ transplant, serious heart conditions, (such as heart failure, coronary artery disease, or cardiomyopathies) Sickle cell disease, Type 2 diabetes mellitus at the discretion of the Investigator Participation in any clinical trial within 30 days of Screening visit Diagnosed Temporo-mandibular joint dysfunction/disorder Participants who wear bruxing devices, dental aligners, retainers Participants who were previously screened and ineligible or were randomized to receive investigational product Participants who are related to those persons involved directly or indirectly with the conduct of this clinical trial (that is, principal investigator, sub-investigators, study coordinators, other site personnel, employees of Johnson & Johnson subsidiaries, contractors of Johnson & Johnson, and the families of each) Other severe acute or chronic medical or psychiatric condition or laboratory abnormality 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 judgment of the Investigator, would make the participant inappropriate for entry into this clinical trial

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Oral Tolerance as Assessed by Clinical Examinations of Oral Hard and Soft Tissues | Oral tissue tolerance will include the assessment of the number of participants with treatment-emergent adverse events (TEAEs) and those experiencing investigational product-related AEs throughout the observational study period of 14 days. In particular, oral examinations will include clinical evaluation of soft and hard tissues, such as buccal and sublingual mucosa, tongue, hard and soft palate, gingiva, uvula, oropharynx, teeth, and dental restorations, with findings recorded in the electronic data capture (EDC) system. | Up to Day 14 | 
| Number of Participants with Adverse Events (AEs) | An AE is any untoward medical occurrence in a clinical study participant temporally associated with the clinical investigation, whether or not the event has a causal relationship to the participant's participation in the trial. | Up to Day 14 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Salivary Flow Rate | Saliva samples will be collected by participants at specified timepoints. The final amount of saliva will be weighed and flow rate will be determined. | Taken at Baseline and immediately (0), and at 2.5, 5, 10, 15, and 30 minute timepoints | 
| Saliva Potential of Hydrogen (pH) | The pH value of saliva will be measured by placing the saliva sample onto the pH-sensitive electrode. | Taken at Baseline and immediately (0), and at 2.5, 5, 10, 15, and 30 minute timepoints |
