Gum disease is common and uncomfortable, but increasing research suggests it may also be connected to a number of unexpected health conditions. Looking after your teeth could therefore be more important than many people realise. Plaque — a sticky film containing bacteria — gradually forms on teeth. If it is not removed through brushing, these bacteria can begin to irritate the gums.
As irritation develops, the gums may become red, tender, or swollen; this early stage is known as gingivitis. In many cases, gum disease can be controlled or avoided through consistent oral hygiene. However, if it progresses further, it may lead to periodontitis, a more serious condition that damages the structures supporting the teeth.
Gum disease, also referred to as periodontal disease, is very common. According to the Centers for Disease Control and Prevention (CDC), nearly half of adults in the United States experience some form of gum disease.
Researchers already understand many of the biological processes involved in periodontal disease, and newer studies indicate that it could also be linked to several other health conditions, including Alzheimer’s disease, certain cancers, and respiratory illnesses. In this overview, we explore some of the surprising associations between gum disease and wider health concerns.
