The loss of gum tissues leads to exposure of teeth roots that are referred as gingival recession or receding gums. It can be considered as the first sign for gum disease. Gum recession creates a gap between gum line and teeth. As a result, disease causing bacteria will severely damage the tissues.
Genes, periodontal disease, aggressive tooth brushing, hormonal changes, and insufficient dental care can be prime reasons for receding gums. Sensitivity of teeth, cavities, exposed roots, swollen gums, gum bleeding and bad breath are general symptoms for receding gums. If receding gums are left untreated, it can even damage bone structure and supporting tissues, which results in tooth loss.
