  • Oral pathology or a history of allergy to testing products;
  • Subject using anticonvulsants, antihistamines, antidepressants, sedatives, tranquilizers, anti-inflammatory medication or daily analgesics within one month prior to the start of the study or scheduled to start such intake during the course of the study; to be defined by the dental examiner;
  • Subject participating in any other clinical study;
  • Subject pregnant or breastfeeding;
  • Subject allergic to oral care products and personal care consumer products
  • Extended use of antibiotics or therapeutic mouthwash (eg: Chlorhexidine) any time during the three months prior to entry into the study;
  • Ongoing use of medications known to affect the gingival tissues (i.e. calcium channel blockers, phenytoin, cyclosporine)
  • Current smokers (or users of tobacco and vaping products) and subjects with a history of alcohol or drug abuse;
  • An existing medical condition which prohibits eating or drinking for periods up to 4 hours.
