"Composition: Potassium Nitrate 5% w/w in toothpaste/gel base. Sodium monofluorophosphate 0.7% w/w (available fluoride content 917 ppm when packed). Mode of Action: Dentinal hypersensitivity is a sharp pain produced in the teeth-, in response to stimuli, such as cold, heat, sweet, sour, or contact. It affects the quality of life and results in extreme discomfort or inability to eat or drink certain foods. It is caused due to opening of the dentinal tubules, after the enamel has been removed by factors such as attrition, abrasion, erosion, or gum recession. RA Thermoseal provides relief from dentinal pain by forming a neurosensory block. Fluoride provides cavity protection. It reduces the demineralization of enamel and dentin by decreasing the acid production of bacterial plaque and decreases the solubility of apatite crystals. It readily becomes incorporated as fluoroapatite layer, to reduce the dissolution of apatite during acid attacks. Indication: Dentinal hypersensitivity. Directions: Adults and children over 12 years of age should apply at least 2.5 cm (1”) strip of the product to a soft bristle toothbrush. Brush teeth to clean all surfaces thoroughly with RA Thermoseal toothpaste/gel at least twice a day (morning and evening), or as recommended by a dentist or doctor. Make sure to brush sensitive areas for a longer time."
