No, gingivitis itself is not contagious. It is not a condition that can be transmitted from one person to another through direct contact or airborne means. Gingivitis develops due to poor oral hygiene and plaque accumulation on the teeth and gums. However, it’s important to note that the bacteria responsible for gingivitis can be present in the mouth and can potentially be transferred through activities such as sharing toothbrushes or other oral hygiene instruments. Therefore, it is recommended to avoid sharing these items to minimize the risk of spreading bacteria and potentially worsening the condition. Additionally, maintaining good oral hygiene practices and seeking appropriate dental care can help prevent the development and progression.
