Toothpaste for Sensitive Teeth
Tooth sensitivity is quite a common problem among a large section of the population, due to which, a great many dental care products have been developed including, the toothpastes for sensitive teeth. The first toothpaste developed for sensitive teeth was ‘Sensodyne’. Denquel is another leading brand of toothpaste for sensitive teeth. Nowadays, a number of different brands of toothpastes have been manufactured to relieve the symptoms of tooth sensitivity. These toothpastes contain some active ingredients like, potassium nitrate and strontium chloride to either restore the tooth enamel or to prevent its further loss. So, the best toothpaste for sensitive teeth is the one, that can meet these basic requirements, besides providing protection against cavities, plaque and softened enamel to maintain dental health.
How Does Toothpaste for Sensitive Teeth Work
As has been mentioned already, there are two main ingredients that are included in a number of toothpastes available for sensitive teeth. These important ingredients are, potassium nitrate and strontium chloride. Potassium nitrate is the salt that desensitizes the nerve roots and thereby, prevents the transmission of the pain stimuli to the pulp and root of the tooth, through the nerves. As the pain signal does not get transmitted to the root of the tooth, tooth sensitivity gets reduced. On the other hand, strontium chloride helps to cover up the tiny pores present in the dentin layer, so that the pain stimuli cannot reach the nerves. So, both the ingredients work to help mitigate the symptoms of tooth sensitivity by desensitizing the tooth nerves and building up a protective barrier on the dentin layer of the tooth.
