What causes gum disease?

Gum disease, also known as periodontal disease, is a common but preventable condition that affects many adults worldwide.

It starts with bacteria in the mouth and can lead to severe damage to the soft tissue and bone that support the teeth, potentially causing teeth to loosen or fall out.

This review explores the common causes of gum disease, translating scientific research into straightforward language.

Gum disease progresses in stages, beginning with gingivitis, which is characterized by red, swollen gums that may bleed during brushing.

If left untreated, gingivitis can advance to periodontitis, a more serious form of gum disease that damages the bones and tissues holding teeth in place.

Understanding the causes and taking preventive measures can help maintain healthy gums and teeth.

Poor Oral Hygiene: The primary cause of gum disease is poor oral hygiene. Without regular brushing and flossing, plaque—a sticky film of food debris, bacteria, and saliva—builds up on the teeth and gums.

Over time, plaque hardens into tartar, which is much tougher to remove and provides a protective shield for bacteria to thrive under, causing inflammation and irritation in the gum tissues.

Smoking and Tobacco Use: Smoking is significantly associated with the onset and progression of gum disease. Studies show that tobacco use can interfere with gum tissue cells’ function, making the mouth more vulnerable to infections, including periodontal diseases.

Smokers are more likely to develop severe gum disease than non-smokers and often experience slower healing after dental treatment.

Genetics: Just as with many health conditions, genetics can play a role in susceptibility to gum disease. Some people are genetically predisposed to periodontal disease, which means despite having good oral care habits, they may still face a higher risk of developing this condition.

Research indicates that individuals with a family history of gum disease should pay extra attention to their oral health.

Hormonal Changes: Changes in hormone levels, such as during pregnancy, puberty, menopause, and monthly menstruation, can make gums more sensitive and more vulnerable to gum disease.

During these times, the body’s response to the toxins produced by the bacteria in plaque can be exaggerated, resulting in more significant gum inflammation and symptoms.

Medications: Some medications can affect oral health because they lessen the flow of saliva, which has a protective effect on teeth and gums. Without enough saliva, the mouth is vulnerable to infections such as gum disease.

Additionally, some drugs, such as the anticonvulsant medication phenytoin and certain types of anti-angina drugs, can cause abnormal growth of gum tissue, which makes it difficult to keep teeth and gums clean.

Diseases: Certain diseases that affect the immune system, like diabetes and HIV/AIDS, can also increase the risk of developing gum disease.

Diabetes, for example, affects the body’s ability to use blood sugar and increases the risk of infections, including gum infections, making it harder to control bacterial infection and inflammation in the gums.

Nutritional Deficiencies: A lack of important nutrients, such as vitamin C, can also contribute to gum disease. Vitamin C is crucial for the maintenance and repair of healthy connective tissue and gums.

A diet low in this vitamin can lead to weakened gum tissue, making it more susceptible to infection and disease.

Prevention is key to managing gum disease, and it starts with maintaining excellent oral hygiene, including regular brushing, flossing, and dental check-ups. Quitting smoking and managing any underlying health conditions that could affect the gums are also critical steps.

For those genetically predisposed to gum disease, more frequent dental check-ups and cleanings might be necessary.

In conclusion, multiple factors contribute to gum disease, from lifestyle choices to genetic predisposition.

Understanding these can help people take proactive steps to prevent the disease or manage its progression effectively. Regular dental visits and good oral care routines are essential in keeping gum disease at bay.
