Teeth more and more long gum recession is mostly due to periodontitis, gum recession can not be restored, only through some ways to slow down the speed of gum recession. 1. Gum recession is due to the persistent stimulation of the gums by plaque within the gums, which leads to redness and swelling of the gums, showing a dark red color and bleeding easily when touched. In the long run, it will lead to loss of attachment, resorption of alveolar bone, deepening of periodontal pockets, resulting in gum recession, and the appearance of longer teeth, wider gaps between the teeth, and even the exposure of the roots of the teeth. 2. persistent periodontitis will also make the teeth appear loose, there is no good way to recover from gum recession, only through the gingival cleaning to remove plaque on the teeth end, and combined with periodontal scraping to remove plaque tartar under the gums, thus slowing down the speed of gum recession. In short, people with gum recession must pay special attention to oral hygiene and health, rinse your mouth after meals every day, floss, brush your teeth two to three times a day, and clean your teeth every three to six months, and perform a thorough periodontal scraping once a year, and only in this way can you slow down the recession of the gums.
