Efficacy of a Potassium Nitrate Containing Herbal Mouthwash to a Potassium Oxalate Mouthwash in Dentinal Hypersensitivity

The goal of this clinical trial is to compare the efficacy of potassium nitrate containing herbal mouthwash to potassium oxalate mouthwash in management of dentinal hypersensitivity. * Participants will be divided into two groups by computer generated randomization. The participants will be divided into two groups, Group 'A' and Group 'B' by Simple Random Allocation as both groups, each group will involve 20 participants with at least two sites showing dentinal hypersensitivity * The assessment of Dentinal Hypersensitivity will be done after scaling and/or root planing (if required) by subjecting affected sites with Air Blast Test (ABT), Cold Water Test (CWT) and Tactile Response assessment will be recorded using Visual Analogue Scale (VAS). All sensitivity tests will be executed by a single examiner who will be blinded to the randomization and will record DH at baseline and at 4, 8 and 12 weeks
