Gum disease, also known as periodontal disease, is a common but often overlooked condition that affects the soft tissue and bone supporting the teeth. It can range from mild inflammation of the gums (gingivitis) to more serious forms that can result in tooth loss (periodontitis). Understanding what causes gum disease is the first step toward preventing and managing this potentially serious oral health issue.

The Role of Plaque
The primary cause of gum disease is dental plaque, a sticky, colorless film of bacteria that constantly forms on your teeth. When you eat, especially sugary or starchy foods, the bacteria in plaque feed on the sugars and release acids. These acids can irritate the gums and start to break down the tooth enamel. If plaque is not removed regularly through brushing and flossing, it can harden into tartar, which only a dental professional can remove. Tartar buildup creates a breeding ground for more bacteria, accelerating gum inflammation and infection.
Inflammation and Infection
As plaque and tartar accumulate, the body’s immune response kicks in to combat the bacterial invasion. This causes inflammation of the gums, which is the hallmark of gingivitis, the earliest stage of gum disease. Gums may become red, swollen, and bleed easily, especially during brushing or flossing. If left untreated, gingivitis can progress to periodontitis, where the inner layer of the gum and bone pull away from the teeth, forming pockets that can become infected. Over time, this can lead to the breakdown of bone and connective tissue, potentially resulting in tooth loss.
Poor Oral Hygiene Habits
Consistent and thorough oral hygiene is essential in preventing gum disease. Failing to brush at least twice a day or to floss daily allows plaque to accumulate, especially along the gumline and between teeth. Skipping regular dental check-ups and cleanings further increases the risk, as tartar buildup can go unnoticed and untreated. Even those who brush and floss regularly but do so ineffectively may still be at risk.
Smoking and Tobacco Use
Tobacco use is a significant risk factor for gum disease. Smoking not only weakens the immune system, making it harder for the body to fight infections, but it also reduces blood flow to the gums, impairing healing. Smokers are more likely to develop periodontal disease and experience more severe forms of it. In fact, tobacco use is one of the leading preventable causes of gum disease worldwide.
Hormonal Changes
Hormonal fluctuations can make gums more sensitive and vulnerable to gum disease. This is particularly true during puberty, menstruation, pregnancy, and menopause. During these times, the gums may react more strongly to the presence of plaque and bacteria, increasing the risk of inflammation and infection. Pregnant individuals, in particular, should be aware of the risk of “pregnancy gingivitis,” which can develop even with good oral care.
Underlying Health Conditions
Certain medical conditions can increase the risk of gum disease. Diabetes, especially when poorly controlled, impairs the body’s ability to fight infections, including those of the gums. Conditions that compromise the immune system can also elevate the risk. Additionally, medications that cause dry mouth or reduce saliva flow can allow plaque to build up more easily, contributing to gum issues.
Genetic Factors
Genetics can also play a role in gum disease susceptibility. Some people may be more prone to gum problems due to inherited traits, even if they maintain good oral hygiene. If you have a family history of gum disease, it’s important to be especially vigilant with dental care and regular checkups.
Diet and Nutrition
What you eat affects your oral health. A diet lacking in essential nutrients can compromise the body’s immune system and reduce its ability to fight infections, including gum infections. High sugar intake can also encourage plaque growth. Eating a balanced diet rich in vitamins and minerals, particularly vitamin C and calcium, can support gum health and reduce disease risk.
