What Is Gum Disease?
Gum disease (periodontal disease) is a bacterial infection of the structures that support your teeth — the gums, periodontal ligament, and jawbone. It begins when plaque, the sticky film of bacteria on your teeth, is not adequately removed through brushing and flossing. Over time, that plaque hardens into tartar, which can only be removed professionally, and the bacteria trigger an immune response that damages the surrounding tissue.
Gum disease is one of the most common chronic conditions in adults worldwide, and because it's often painless in its early stages, many people don't realize they have it until significant damage has occurred.
The Two Main Stages
Stage 1: Gingivitis
Gingivitis is the early, reversible stage of gum disease. It's confined to the gums and hasn't yet affected the bone or deeper supporting structures.
Symptoms include:
- Red, swollen, or puffy gums
- Gums that bleed easily when brushing or flossing
- Persistent bad breath
- Gums that feel tender to the touch
Good news: Gingivitis is fully reversible with a professional cleaning and improved home care. At this stage, no bone or tissue has been permanently lost.
Stage 2: Periodontitis
If gingivitis goes untreated, it can advance to periodontitis — a more serious, destructive condition where infection spreads below the gum line. The gums begin to pull away from the teeth, forming pockets that trap bacteria. The immune system's response starts to destroy the bone and connective tissue holding teeth in place.
Symptoms include:
- Gums that have pulled away (receded) from teeth, making teeth look longer
- Persistent bad taste or bad breath
- Loose or shifting teeth
- Pus between teeth and gums
- Changes in bite alignment
- Pain when chewing (in more advanced cases)
Risk Factors for Gum Disease
- Smoking or tobacco use — significantly impairs gum healing and masks symptoms
- Diabetes — impairs the body's ability to fight infection
- Hormonal changes — pregnancy, puberty, and menopause can increase gum sensitivity
- Certain medications — some drugs reduce saliva flow or cause gum overgrowth
- Family history — genetics plays a role in susceptibility
- Poor nutrition — particularly vitamin C deficiency
Treatment Options by Stage
| Stage | Treatment | Can It Be Reversed? |
|---|---|---|
| Gingivitis | Professional cleaning + improved home hygiene | Yes, fully reversible |
| Mild periodontitis | Scaling and root planing (deep cleaning) | Manageable, not fully reversible |
| Moderate periodontitis | Deep cleaning + possible antibiotics or antimicrobials | Manageable with treatment |
| Severe periodontitis | Periodontal surgery, bone grafts, tooth extraction if needed | Requires ongoing management |
Scaling and Root Planing
The most common non-surgical treatment for periodontitis is scaling and root planing (also called a deep cleaning). Your hygienist or periodontist uses instruments to remove tartar from below the gum line and smooth the root surfaces to discourage bacterial reattachment. This is usually done in quadrants over multiple appointments, often under local anesthesia.
The Connection Between Gum Disease and Overall Health
Research has increasingly linked periodontal disease to broader health conditions. Chronic gum inflammation has been associated with a higher risk of cardiovascular disease, poorly controlled diabetes, respiratory infections, and adverse pregnancy outcomes. While the relationship is still being studied, the connection highlights why treating gum disease is about more than just saving teeth.
How to Prevent Gum Disease
- Brush twice daily with a soft-bristled toothbrush and fluoride toothpaste
- Floss once daily to remove plaque between teeth
- Attend regular dental checkups and professional cleanings
- Avoid tobacco products
- Eat a balanced diet low in sugar
- Stay hydrated to maintain healthy saliva flow
When to See a Dentist
If your gums bleed regularly, look red or swollen, or if you've noticed your teeth shifting, don't wait. Early intervention makes an enormous difference in outcomes. Your dentist or periodontist can assess gum health and create a personalized treatment plan.
