First, the gingival recession will have on the human skeleton in a special part of the alveolar bone of the declining ability to transport nutrients, alveolar bone will shrink shorter, gingival recession that led to this "micro-joints" to maintain the strength of the parcel lower teeth began to loosen, and the alveolar bone is absorbed, shallow roots of the teeth, the teeth longer, with the growing phenomenon of increased bone resorption, teeth naturally fall out.
Second, the gingival recession also led to the exposed roots (dentin part), root surface with no enamel, but once the gums to protect not only easy to brush your teeth are worn, while cold, heat, acid is very sensitive to stimulation, oral medicine called "dentin hypersensitivity."
Finally, gingival recession after root can not be dental instruments done before, wrapped tightly, resulting in periodontal tissue (within the gum) is also exposed, in a variety of oral bacteria (particularly anaerobic bacteria) and tartar direct invasion of periodontal tissue lead to periodontitis. Periodontitis in turn exacerbate gingival recession, accelerated alveolar bone is absorbed, forming a vicious circle, and periodontitis by the World Health Organization as a threat to human health, the third largest killer.
