Gums recede for several different reasons. The primary cause of gum recession is due to gum disease. When bacteria invade the area around the tooth it causes the gums to detach and creep farther down the root. Other causes include the use of tobacco, abrasive toothbrushing techniques, tooth misalignment and grinding.
A Dr. Supriya Verma, Dentist, answered. Receding gums can lead to a cavity because as the gum tissue goes further down the tooth the roots can get exposed. Roots are made of a much softer material then the crown of the tooth and can wear away more easily and expose the underlying dentin.
