Signs and Causes of Gum Disease
Because it advances painlessly, most patients present late; recognising the signs allows early treatment.
Signs to watch for
- Bleeding when brushing or flossing
- Red, swollen or tender gums
- Persistent bad breath or taste
- Receding gums and teeth appearing longer
- Cold sensitivity from exposed root surfaces
- Loose teeth or a changing bite
- Pus discharge from the gum
Plaque and calculus
The primary cause is bacterial plaque, which mineralises into calculus. Its rough surface holds more plaque, cannot be brushed off, and extends into the sulcus to form a pocket where bacteria are sheltered — a self-reinforcing cycle.
Risk factors
Smoking is the strongest risk factor: it constricts vessels and suppresses bleeding, hiding progression and reducing response to treatment. Uncontrolled diabetes impairs healing, and the relationship runs both ways.
Gum recession
Recession is not always inflammatory: hard brushing, poor technique and a stiff brush also cause it. Receded gum does not grow back, and the exposed root is sensitive and prone to decay; grafting may be considered.
Stages of Periodontal Treatment
Treatment is staged, with the response assessed before moving on.
Examination and pocket charting
Pocket depths are measured with a probe and recorded, while a radiograph shows bone level. Together they determine the diagnosis and plan, and are repeated afterwards to measure response objectively.
Scaling
Plaque and calculus are removed with ultrasonic and hand instruments; at the gingivitis stage this is often sufficient. Scaling does not erode teeth — the spaces felt afterwards were already there, filled with calculus.
Root planing
Where pockets have deepened, cleaning extends beneath the gum to the root surface under local anaesthesia, allowing the gum to reattach. Pockets are re-measured weeks later.
Surgical treatment and grafts
Where pockets are too deep for closed treatment, surgical access allows direct cleaning; grafting and guided tissue regeneration may recover some bone in suitable cases.
Maintenance and the Link With General Health
Periodontal treatment is ongoing care, not a one-off procedure.
Why maintenance is essential
Cleaned pockets re-colonise if plaque control lapses, and a previously affected mouth remains at higher risk. Maintenance intervals are set individually, and regular maintenance markedly reduces long-term tooth loss.
Home care
- Brushing twice daily with a soft brush and correct technique
- Floss or interdental brushes, since a brush cannot enter between teeth
- Angling the brush 45 degrees to the gum margin
- Avoiding hard brushing, which increases recession
- Cleaning the tongue, a major source of halitosis
- Stopping smoking, the factor with the greatest effect on outcome
Gum disease and general health
Gum inflammation is a chronic inflammatory focus contributing to the body's overall burden. The link with diabetes is two-way, so periodontal follow-up is part of care for diabetic patients.
Surgical and Supportive Treatment in Advanced Cases
When non-surgical cleaning is not sufficient, surgical approaches address deep pockets and bone loss.
When surgical treatment becomes necessary
Surgery is not the first step: tissues are reassessed after scaling and root planing. Where pockets remain too deep to clean, the gum is reflected to give direct access to the root surface and repositioned, creating an area that can actually be maintained.
Gum and bone grafts
In suitable defects, grafts and barrier membranes are used to regain lost bone; defect shape determines what is achievable. Connective tissue grafts can cover exposed roots where recession causes sensitivity or aesthetic concern. Controlled inflammation and not smoking strongly affect the outcome.
Gum problems around implants
Implants do not decay, but surrounding tissues react to plaque: peri-implant mucositis involves bleeding and swelling, while peri-implantitis adds bone loss. Early detection allows management with cleaning and hygiene changes; advanced cases require surgery.
Home Care: Correct Technique and Common Mistakes
The durability of clinical treatment depends largely on daily care between appointments.
Brushing technique and duration
The target zone is the margin where tooth meets gum: place the brush at about 45 degrees and use small vibratory strokes. Hard pressure does not clean better — it causes recession and abrasion. Around two minutes, evenly distributed, with a soft to medium brush.
Why interdental cleaning is indispensable
A brush cannot reach the surfaces between teeth, where gum inflammation typically begins. Floss suits tight contacts; interdental brushes suit wider spaces, and the correct size should be selected professionally. Early slight bleeding reflects inflammation and reduces with regular cleaning.
Common mistakes in gum care
- Stopping brushing an area because it bleeds
- Using a hard brush with heavy horizontal scrubbing
- Skipping interdental cleaning altogether
- Treating mouthwash as a substitute for brushing
- Forcing toothpicks into the gum
- Abandoning maintenance visits once symptoms subside
- Requesting scaling only when calculus becomes visible
