To be used twice daily for 4 weeks CONDITION: Health Condition 1: K088‐ Other specified disorders of teethand supporting structures PRIMARY OUTCOME: 1.Objective assessment of the sensitivity of hard tooth tissue, an index of the intensity of teeth hyperesthesia (IIGZ) will be used ; 2.A visual analogue scale is proposed for self‐assessment by the participant of the level of pain in the samples, where the values from 1 to 3 corresponded to the light intensity of pain, from 4 to 6 points ‐ moderate, and 7 or higher strong ; 3.To evaluate the cleaning effect of studied products Oral Hygiene Index Simplified (OHI‐S) [ Time Frame: Baseline to 4 weeks] ; 4. Air Blast Hypersensitivity [ during each visit over 1‐4 weeks] ; 5. Examiner rates the response to stimulation of hypersensitive teeth using a jet of air (constant stimulus based on duration, pressure, temperature, distance from target). Response is rated based on the Schiff Cold Air Sensitivity Scale. ; 6. Reductions in extrinsic tooth stain area and extrinsic tooth stain intensity. ; 7. Photographic AssessmentTimepoint: Baseline,Week 1, Week 2 , Week 3 and Week 4 SECONDARY OUTCOME: Participant and Investigator Feedback will be obtained before enrollment and after completion of the study ; Adverse event monitoringTimepoint: Baseline,Week 1, Week 2 , Week 3 and Week 4 INCLUSION CRITERIA: 1. Participants aged 18 to 50 years. 2. Presence of a minimum of 20 teeth. 3.Presence of tooth sensitivity (inde Xof the intensity of teeth hyperesthesia, IIGZ score greater than 2). 4.Adequate oral hygiene and no signs of oral neglect. 5. Qualifying response to the Air Blast stimuli as defined by a score of 2 or 3 on the Schiff Cold Air Sensitivity Scale. 6. Use of a non‐desensitizing dentifrice for one month prior to entry into the study. Participant is willing to provide informed consent and is willing to participate in all procedures and follow up evaluations necessary to complete the study 7.
