Is it normal to have receding gums? NO.
Gum recession can be caused by occlusal stress related to sleep disordered breathing, gingivitis, improper tooth brushing and flossing and/or genetics and hormonal changes. At the first sign of recession see your dentist to obtain a proper evaluation for treatment of the specific cause. If left untreated this condition could cause the loss of the affected teeth.
