Gum recession is usually a sign of inflammation of the gums. The main treatment is to treat the inflammation of the gums. If the gum recession is only caused by gingivitis, you can have your teeth scaled. Scaling is the use of ultrasonic vibration to remove plaque and calculus around the teeth and other irritants, followed by alternating local rinses with 3% hydrogen peroxide and saline, then applying iodine glycerin or Paregoric ointment to the gums for local anti-inflammation, and then rinsing with mouthwash. Commonly used mouthwashes include chlorhexidine solution, rehabilitating solution and tinidazole solution, etc. The use of mouthwash can consolidate the effect of scaling, maintain the flora environment in the mouth and keep the oral hygiene. This will allow the gingivitis to heal and not continue to progress so that the gums will slowly return to their original position. In the case of gum recession caused by periodontitis, not only scaling but also subgingival scaling should be done. In early periodontitis after systematic basic treatment, the gums will return to their normal position. In the case of severe periodontitis, with deep periodontal pockets and a lot of alveolar bone resorption, the roots of the teeth are severely exposed, in which case the gums cannot be restored. Therefore, for periodontal diseases, it is important to achieve early diagnosis and early treatment to control periodontal diseases at an early stage, so that they do not develop into more serious consequences at a later stage.
