Gingival recession

Gingival recession, also known as receding gums, is the exposure in the roots of the teeth caused by a loss of gum tissue and/or retraction of the gingival margin from the crown of the teeth. Gum recession is a common problem in adults over the age of 40, but it may also occur starting from the age of a teenager, or around the age of 10. It may exist with or without concomitant decrease in crown-to-root ratio (recession of alveolar bone).
