Various grafting procedures are available to stop further dental problems and gum recession, and/or to improve the esthetics of your gum line. Exposed tooth roots are the result of gum recession.

Or, maybe you're not bothered by the appearance of these areas, but you cringe because the exposed roots are sensitive to hot or cold foods and liquids.
