Gum recession resulting in an enlarged gap should not be treated with a filling. Because it is not a specific dental defect in itself, it is possible to prepare better resistant or cemented cavities and apply filling materials to fill them. The main cause of large gaps in the teeth due to gum recession, the most common disease causing gum recession is periodontitis, which is the number one risk factor for total tooth loss in middle-aged and elderly people. Typical symptoms of periodontitis are gum recession, alveolar bone resorption, and finally the gradual loosening and loss of teeth. For the treatment of periodontitis, it is important to go to a professional dentist for systematic periodontal treatment, including supragingival cleaning, subgingival scraping, root planing, periodontal surgery and so on. All of the above treatments are designed to stop the progression of periodontitis so that the gums do not continue to recede.
