Toothpaste for sensitivity?

One of the main causes of tooth sensitivity is receding gums. When this happens a small part of the root of the tooth becomes uncovered and it is this which reacts to hot and cold causing discomfort. I find the best toothpastes to give rapid relief are either Sensodyne Repair and Protect or Sensodyne Complete Protection. When the sensitivity reduces I then recommend Oral B Pro-Expert for long term use.
