Gum (periodontal) disease is an infection of the gums and can affect the bone structure that supports your teeth.
In severe cases, it can make your teeth fall out. Smoking is an important cause of severe gum disease in the United States.
Smoking weakens your body's infection fighters (your immune system). This makes it harder to fight off a gum infection. Once you have gum damage, smoking also makes it harder for your gums to heal.
Tobacco use in any form—cigarettes, pipes, and smokeless (spit) tobacco—raises your risk for gum disease.
