Why Gum Disease Is More Common Than You Think
Gum disease, also called periodontal disease, is a common oral health condition that affects millions of people worldwide. According to the World Health Organization (WHO), periodontal disease affects about 19% of the global adult population, which equals more than one billion cases worldwide.
Often described as a “silent disease,” gum disease causes inflammation and infection of the gums due to plaque buildup on teeth. Many people do not realise they have it until the condition worsens. If left untreated, gum disease can lead to serious oral health problems and even affect overall health.
Why Early Detection Matters
Recognising the signs of gum disease early is important for preventing long-term damage.

How to prevent gum disease
By identifying the symptoms early, you can take proactive steps to protect your oral health and maintain a healthy smile.
What Is Gum Disease?
Gum disease refers to inflammatory conditions that affect the tissues supporting the teeth.
The most common form is gingivitis, which causes redness, swelling and bleeding of the gums.
If gingivitis is not treated, it can develop into periodontitis, a more serious infection that damages the tissues and bone supporting the teeth. In severe cases, this damage may lead to loose teeth or tooth loss. Research also links advanced gum disease to other health conditions in the body.
What Causes Gum Disease?
The main cause of gum disease is plaque buildup on the teeth, often due to poor oral hygiene.
Plaque is a sticky layer of bacteria that constantly forms on the surface of teeth. If brushing and flossing do not remove it regularly, plaque can harden into tartar, which dentists can only remove with professional cleaning.
As plaque accumulates, bacteria irritate the gums and trigger inflammation. Over time, this inflammation can damage the gum tissue and the structures that support the teeth.

What Happens at the Molecular Level?
At a microscopic level, gum disease develops through a complex interaction between harmful bacteria and the body’s immune system.
Certain bacteria — such as Porphyromonas gingivalis and Tannerella forsythia — can accumulate along the gum line and form a bacterial biofilm on teeth. This triggers the body’s immune response.
In response, the immune system releases inflammatory chemicals and enzymes, including matrix metalloproteinases (MMPs). These substances help fight infection but can also break down surrounding gum tissue and supporting structures.
Over time, this ongoing inflammation can damage the connective tissue and bone that support the teeth. As the disease progresses, the attachment between the tooth and gum weakens, eventually leading to periodontitis.
Gum disease is often called a “silent disease” because it usually causes little or no pain in its early stages. Many patients only notice symptoms once the condition becomes more advanced.
Symptoms of Gum Disease
Recognising the symptoms of gum disease is essential for early treatment. The signs may vary depending on the severity of the condition.
Early Symptoms of Gum Disease
In the early stages, symptoms may appear mild and are often easy to overlook. Common early signs include:
Red or swollen gums
Healthy gums should appear pink and firm. Redness or swelling may indicate inflammation.
Bleeding during brushing or flossing
Bleeding gums are often one of the first warning signs of gum disease.
Persistent bad breath
Also known as halitosis, this may result from bacteria accumulating in the mouth.
Tooth sensitivity
Inflamed gums may cause increased sensitivity to hot or cold foods and drinks.
These early symptoms should not be ignored. They signal inflammation in the gums and may indicate the beginning of gum disease. If left untreated, the condition can progress and lead to more serious oral health problems. PRIME
