There is an increasing interest in the link between periodontitis and overall cancer risk. The circulating inflammation caused by gum disease and transfer of harmful bacteria from the dental pockets into the bloodstream might be the connection. However, evidence for this is not strong.
There are many common risk factors between gum disease and cancer, such as smoking, age, alcohol and family history.
Professional treatment of gum disease and good oral hygiene will result in a healthier mouth with less inflammation, which is a benefit to everyone.
