potassium nitrate

The ingredient approved in clinical tests for use in treating tooth sensitivity. It seeps into the dentin microchannels, reaching the nerves inside, the potassium nitrate blocks the signals that the nerves in the teeth send to the brain. It usually takes several uses of the toothpaste before the necessary doze stays in the microchannels to block the feeling of tooth sensitivity and before you start to feel the difference.
