Gum disease, also known as periodontal disease, is not directly contagious in the way that a cold or flu might be. However, certain bacteria associated with gum disease can be transferred between people through close contact, such as kissing or sharing utensils. This doesn’t mean you will necessarily develop gum disease just because you were in close contact with someone who has it, but it does increase the likelihood of exposure to harmful bacteria that contribute to the condition.
The main cause of gum disease is poor oral hygiene, which leads to the buildup of plaque on teeth. Plaque is a sticky, colorless film of bacteria that forms on your teeth, and if not removed through regular brushing and flossing, it can lead to inflammation of the gums (gingivitis) and eventually more serious periodontal disease.
Risk factors for developing gum disease include smoking, poor nutrition, certain medications, diabetes, and a family history of gum disease. While you may be exposed to the bacteria, the disease itself often develops based on your oral care habits, immune response, and other personal factors.
To reduce the risk of gum disease, it’s important to practice good oral hygiene by brushing and flossing regularly, visiting a dentist for routine cleanings, and maintaining a healthy lifestyle.
