Gum disease mainly includes the following: first, gingivitis and periodontitis, these two diseases usually use ultrasonic scaling, periodontal subgingival scaling, root planing, and periodontal rinsing and drugging, etc. Its main symptoms are red and swollen gums, easy bleeding, and bad taste in the mouth, and patients with periodontitis will have different degrees of alveolar bone resorption, gum recession and root exposure. Second, gingival papillitis, the disease is mainly due to long-term food embedding pressure on the gingival papilla, resulting in inflammation of the gingival papilla, so in the treatment to remove the food between the teeth, the inflamed gingival papilla for rinsing and drugging, local application of iodine glycerin and other anti-inflammatory. Third, gingival tumors, gingival tumors are mostly due to long-term inflammatory stimulation of the gums to form hyperplasia, polyps, generally using the method of periodontal cleaning, cleaning and treatment of some gingival tumors can be self-absorption. If they cannot be absorbed and are still large, they need to be removed surgically. If the gum tumor is caused by drug gum hyperplasia, some people can recover their original state after stopping the drug, but some people’s gum tumors are still very large and need to be removed by surgery. Fourth, oral cancer, also known as gum cancer, needs to be removed surgically first, and then pathology is done to determine the treatment plan according to the pathology results.
