The study design is a randomised, split mouth, blind with respect to study analysts (microscopist, image grader) two treatment clinical study in 10 healthy participants with sound tooth enamel. The study will comprise of a screening visit, pre-baseline visit and 5 subsequent clinic visits. At the screening visit, participants will give consent to participate in the study. Medical history and concomitant medications will be recorded. Eligibility will be determined following an oral soft tissue (OST) examination and an evaluation of dentition exclusions. Two suitable anterior teeth will be identified for study assessments, these teeth must be at least one tooth apart in the mouth. Saliva samples will be collected from the participants at set points during the study to look at any changes in salivary pH.

Be susceptible to high dental erosion after drinking acidic soft drinks or juices 4. General Dental Exclusions 1. Any orthodontic appliances, restorations, bridgework or dentures that would interfere with the study evaluations or scheduled for such treatment within the timescale of the study. 2. Recurrent or regular aphthous ulcers. 3. Severe gingivitis, carious lesions treated and untreated periodontal disease. 4. Excessive signs of dental erosion or a previous history of being susceptible to high dental erosion after drinking acidic drinks 5. Tooth bleaching within past 2 months. 6. Suffer from dentine hypersensitivity. 5. Allergy/Intolerance Known or suspected intolerance or hypersensitivity to the study materials (or closely related compounds) or any of their stated ingredients. 6.
