Understanding Gum Disease

Gum disease (periodontal disease) affects nearly half of American adults over 30, yet most people don't know they have it until significant damage has occurred. It progresses silently — the mouth doesn't always hurt, which is why regular dental visits are essential for catching it early.

What Causes It?

Bacteria. Your mouth naturally contains hundreds of bacterial species, most harmless. When plaque — that sticky bacterial film — accumulates along the gumline and hardens into tartar, certain bacteria produce toxins that trigger your immune system. The resulting inflammation is the disease, not the bacteria themselves. This is why gum disease is both an infection and an inflammatory condition.

The Two Stages

Gingivitis: Gums are red, swollen, and bleed when you brush or floss. This is your body's alarm signal. At this stage, the disease is completely reversible — a professional cleaning and improved home care resolve it. Many people dismiss bleeding gums as normal; they are not. Healthy gums do not bleed.

Periodontitis: When gingivitis is untreated, the infection moves below the gumline. Pockets form between the gum and tooth root — spaces where bacteria accumulate beyond the reach of a toothbrush. The body's immune response, in trying to fight the infection, destroys the bone and connective tissue holding the tooth. Bone loss is permanent. Teeth may loosen and eventually be lost.

Warning Signs

• Bleeding when brushing or flossing
• Red, swollen, or tender gums
• Persistent bad breath
• Gums pulling away from teeth (recession)
• Loose or shifting teeth
• Pain when chewing

Treatment

Early-stage (gingivitis): regular cleaning and better home care. Moderate-to-advanced periodontitis: "deep cleaning" — a procedure called scaling and root planing where tartar is removed from below the gumline under local anesthesia. Severe cases may require surgical intervention. The key point: all stages of gum disease are treatable, and most cases can be managed with non-surgical care when caught before advanced bone loss.
