Tooth sensitivity is discomfort or sharp pain felt during drinking cold or hot beverages and even by brushing the teeth. This happens because dentin (inner layer of the teeth) is exposed due to various reasons, such as gum recessions and cracked tooth.
There are natural remedies for tooth sensitivity and there are treatments that need the help of a dentist. Natural remedies you can practice are by using soft-bristled toothbrush, avoid consuming highly acidic foods and use mouth guard if you are grinding the teeth. If these measures did not give relief then consider the help of a dentist and dental products. During dental visit, the dentist may suggest using desensitizing toothpaste or recommend an in-office treatment, such as tooth filling to cover the dentin, putting a crown, sealants and root canal if it is a serious case.
