The patient presents with gingivitis, generally due to intrinsic causes. It could be caused by the patient's internal heat leading to inflamed gums, resulting in gingivitis and periodontitis. Typically, kissing does not lead to transmission because it is not a contagious disease. It is advised that the patient pays attention to their oral hygiene, regularly undergoes dental cleaning, and avoids causing other dental diseases. Gingivitis and oral ulcers do not spread through kissing. However, it is recommended that the patient seeks timely treatment and avoids kissing during this time. While it does not cause contagion, it can lead to the spread of some bacteria in the mouth, which may exacerbate the condition. Therefore, early treatment is advised, but there is no need for excessive worry.
