• Evidence of a personally signed and dated informed consent document indicating the participant (or legally acceptable representative) has been informed of all pertinent aspects of the trial
• Able to read and understand the local language (participant is capable of reading the documents)

• 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
• Resting baseline unstimulated salivary sample must be equal to or greater than 0.3 mL/min to continue in the clinical trial
• A minimum of 20 natural teeth with scorable facial and lingual surfaces. 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 Visit 1
• 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 at Visit 1. Intermittent use of certain antiinflammatory 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 (CPC), sodium fluoride with CPC, stannous fluoride, zinc or chlorhexidine digluconate containing mouthwashes and toothpastes within the four weeks prior to Visit 1
• 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, COPD (chronic obstructive pulmonary disease), 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 Visit 1
• 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 (i.e., 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
