Gum recession occurs when there is a loss of the thick gum tissue that normally covers and protects the root.The root becomes exposed, and the remaining gum tissue is often thin and more susceptible to irritation or inflammation.The exposed root can be unsightly and make the tooth sensitive to hot or cold.Additionally, the exposed root is softer than the enamel of the tooth, which makes it more susceptible to decay or cavities.
Fortunately areas of recession can be treated, often leading to complete coverage of the exposed root.Several types of procedures can be used to treat recession, and are covered in our section onGum Grafting.
