Gingivitis should be treated by first identifying the causative factors and then treating the disease accordingly. Gum inflammation is a common oral manifestation, mostly seen in people with poor oral hygiene, who do not brush their teeth in time after eating, and food debris or soft scale accumulates around the gums of the teeth, leaving the gum tissue in a congested state for a long time, causing the gums to bleed. The treatment of gum inflammation first needs to remove local irritants, you can use ultrasonic cleaning to remove tartar plaque, etc., and then gum local rinse and medication to improve the symptoms. If periodontitis is the cause of bone loss, periodontal treatment such as subgingival scaling and, if necessary, bone-guided regeneration should be performed. Gingival inflammation may also be related to certain hormonal changes, such as adolescent gingivitis, which often occurs in areas where local irritants are present in the gingival area, such as areas where teeth are erupting, replacing teeth, mouth breathing, and teeth undergoing orthodontic treatment. In adolescents, endocrine changes cause the gingival tissues to have a very pronounced inflammatory response to those minor local irritants and the symptoms of adolescent gingivitis occur. There is also gingivitis during pregnancy, where the gums can bleed due to changes in estrogen and progesterone levels, with the gums acting as the target organ. In this case, it is important to maintain oral hygiene, brush and rinse your teeth regularly until the pregnancy period is over, and the inflammation of the gums can usually be relieved on its own. Certain medications can also cause drug-increased gingivitis, such as phenytoin sodium, which needs to be changed or stopped in a timely manner under the guidance of a specialist.
