Gingival recession is when the gingival margin of the gums recedes toward the root of the tooth and exposes the root, eventually leading to tooth loss, but there is no functional loss of gingival recession. It becomes more severe the older you get. So what exactly causes receding gums? We only list here a few common causes: 1, improper brushing if we use too hard toothbrushes in our daily life, too coarse particles of rubbing agent in toothpaste, saw-like horizontal brushing, etc. can cause gum recession. 2, inappropriate dentures if dentures stimulate the gingival edge, resulting in its inflammation, in the long run, will also cause gum recession 3, inappropriate orthodontic force or bite force is too large orthodontic force or bite force is too large will make the teeth tilt, followed by gum recession 4, periodontitis treatment if suffering from severe periodontitis, the treatment of inflammation eliminated or periodontal surgery to expose the roots of the teeth, will also lead to gum recession. In short, to have a healthy teeth, we all need to work together.
