Smoking can lead to heart and lung disease, including many types of cancer. You can add gum disease to the growing list of conditions caused by tobacco.
Gum disease, or periodontal disease, is a condition that destroys the bone that supports your teeth. People who smoke more than one and a half packs of cigarettes a day were nearly five times more likely to have advanced periodontitis, according to one study.
Gum disease can occur in non-smokers as well, especially if they don’t regularly brush or floss their teeth.
