Inclusion Criteria: * Participants aged 18-50 years with a preoperative VAS score of ≥2 for dentinal hypersensitivity. * Participants with sensitivity due to gingival recession, cervical abrasion, or enamel erosion. * Participants with good systemic health. * Minimum of two hypersensitive teeth present in two different quadrants. Exclusion Criteria: * Teeth with caries, defective restorations, or cervical defects \> 2 mm (may affect sensitivity measurements). * Periodontal surgery or deep periodontal pockets (\> 6 mm) within the past three months (potential influence on periodontal health and sensitivity). * Participants using desensitizing toothpaste within the past three months (could interfere with study outcomes). * Presence of gross oral pathology or systemic diseases (e.g., eating disorders, chronic diseases, uncontrolled metabolic conditions) (may alter oral health status). * Pregnant or lactating women (hormonal changes can influence oral health).
