Improper heavy handed brushing of the teeth. It is estimated that 50-90% of people brush with too much pressure. Over weeks, months and years of brushing they remove significant gum tissue exposing the tooth roots.

Bacteria in this tartar are responsible for the gingivitis and periodontal disease that cause gum recession
