Gum Disease

The Three Stages of Gum Disease

Gingivitis

Gingivitis is the earliest form of gum disease. At this stage, only the gum tissue is affected — the bone and ligaments supporting the teeth are still intact.

The most common sign is gums that bleed when you brush or floss. Redness, puffiness, and mild tenderness are also typical.

The critical point: gingivitis is fully reversible. With a professional clean and better home care, gums can return to full health. No permanent damage has occurred yet.

Periodontitis

If gingivitis is left untreated, it can advance to periodontitis. This is when the infection moves below the gum line and begins breaking down the bone and connective tissue that anchor the teeth.

As this happens, the gums start pulling away from the teeth — creating pockets where bacteria collect and cause further damage. These pockets deepen over time.

Unlike gingivitis, the bone loss caused by periodontitis is permanent. Treatment can stop the disease from progressing, but lost bone does not regenerate on its own.

Advanced Periodontitis

In severe cases, bone destruction becomes extensive enough that teeth loosen, shift position, or can no longer be saved. This is the stage at which tooth loss is most likely to occur.

It is not an inevitable outcome — but it is the result of a condition that went without treatment for a significant period of time.

Causes and Risk Factors

The Root Cause: Plaque

Gum disease begins with plaque — a biofilm, or soft sticky layer of bacteria, that builds up on teeth and along the gum line every day.

When plaque is not cleared through brushing and flossing, it triggers inflammation in the surrounding gum tissue. Left longer, it hardens into calculus (tartar) — a rough, mineralized deposit that cannot be removed at home. Only a dental professional can remove tartar.

Factors That Increase Your Risk

Some people are more susceptible to gum disease than others. The most significant risk factors include:

• Smoking and tobacco use — one of the strongest known risk factors; tobacco impairs the gum tissue's ability to heal and can mask early bleeding
• Poorly controlled diabetes — elevated blood sugar accelerates bacterial growth and weakens the immune response in gum tissue
• Hormonal changes — pregnancy, menopause, and puberty can all increase gum sensitivity and susceptibility to inflammation
• Certain medications — some drugs reduce saliva flow or cause gum tissue to overgrow, both of which raise periodontal risk
• Genetic predisposition — some people are inherently more prone to aggressive forms of gum disease, even with consistent oral hygiene
• Chronic stress — prolonged stress suppresses immune function, reducing the body's ability to control bacterial infection
• Dry mouth (xerostomia) — saliva helps neutralize acids and clear bacteria; reduced saliva flow increases risk at both the teeth and gums
• Teeth grinding (bruxism) — the repeated mechanical pressure of grinding accelerates tissue and bone damage in patients who already have periodontal disease

Symptoms to Watch For

Gum disease is often called a silent condition — it can develop for years without causing significant pain. Many patients discover they have it only during a routine dental examination.

That said, these are the signs worth acting on:

• Gums that bleed during brushing or flossing
• Red, swollen, or tender gums
• Gums that appear to be receding, making teeth look longer than before
• Persistent bad breath that does not clear with brushing
• A bad or unusual taste in the mouth
• Visible pus around the gum line
• Teeth that feel loose or have shifted
• Changes in how your teeth meet when you bite down
• Sensitivity near the gum line to hot or cold

Any of these signs warrants a professional assessment. Early detection makes a significant difference in how straightforward treatment is.

How Gum Disease Is Diagnosed

You may notice some of the signs yourself — bleeding gums, recession, or persistent bad breath. But confirming the presence and extent of gum disease requires a clinical examination.

During the examination, the dentist will measure the depth of the spaces between your gums and teeth using a small instrument called a periodontal probe. These readings, taken alongside X-rays and a visual assessment, help determine whether disease is present and how far it has progressed.

X-rays are taken to assess bone levels around each tooth — something that cannot be determined visually. In more complex cases, a cone beam CT (CBCT) scan may be used for a detailed three-dimensional view.

Based on these findings, a Specialist Periodontist will determine the stage and severity of the disease and discuss the appropriate path forward.

Why Gum Disease Should Not Be Left Untreated

• Tooth Loss

  The most direct consequence of untreated periodontitis is tooth loss. As supporting bone is progressively destroyed, teeth lose their anchorage. Once teeth are lost, surrounding teeth may shift, bite function changes, and the jawbone begins to shrink in the area of the gap.

• It Does Not Stay Still

  Gum disease is progressive. Without treatment, what begins as mild periodontitis can advance to severe bone loss within a few years — particularly in patients with risk factors such as diabetes or smoking.

• It Affects Implant Outcomes

  For patients who have lost teeth and are considering dental implants, active gum disease is a significant contraindication. Periodontal infection in the mouth substantially increases the risk of implant failure. The disease must be fully brought under control before implant placement can proceed.

Gum Disease and Your Overall Health

The mouth and body are connected — and gum disease has been linked to a number of systemic health conditions.

• Heart Disease and Stroke

  Research published in the Journal of Clinical Periodontology has found associations between periodontal disease and an elevated risk of cardiovascular events, including heart attack and stroke. The likely mechanism involves oral bacteria entering the bloodstream and contributing to arterial inflammation.

• Diabetes

  The relationship between gum disease and diabetes runs in both directions. Poorly controlled blood sugar worsens periodontal disease, and active gum infection can make blood sugar harder to manage. Treating gum disease has been shown in multiple studies to contribute to improved glycemic control.

• Pregnancy

  Evidence links periodontal disease to a higher risk of preterm birth and low birth weight. Pregnant patients are advised to have their gum health assessed as part of routine prenatal care.

• Respiratory Health

  Bacteria from the mouth can be aspirated into the lungs, contributing to respiratory infections. This is of particular concern for older patients and those with existing lung conditions.

Preventing Gum Disease

In most cases, gum disease is preventable. The foundations are straightforward:

• Brush twice daily with a soft-bristled toothbrush for at least two minutes
• Floss once daily to clear plaque from between teeth and just below the gum line
• Attend regular professional cleaning appointments — your hygienist has the specialized tools and training to remove tartar that brushing and flossing simply cannot reach
• Avoid smoking and tobacco use
• Manage conditions such as diabetes in partnership with your physician
• Tell your dentist about any medications you take, as some carry periodontal side effects

For patients with a genetic predisposition, more frequent professional monitoring may be recommended — regardless of how consistent home care is.
