Gum disease is one of the most common oral conditions, affecting 7 in 10 adults at some point. What makes it dangerous is that it can progress silently to tooth loss without obvious early symptoms. In this article, the ClinicsJo Editorial Team explains the stages of gum disease, warning signs, treatment, and how to protect your gums.
What Is Gum Disease?
The gum is a pink tissue surrounding the bases of teeth and protecting them. When bacteria and plaque (sticky deposits) accumulate on tooth surfaces and edges, the gum becomes irritated and starts to bleed. This early stage is called gingivitis, and is fully reversible. Untreated, it progresses to periodontitis, where bone supporting the tooth is damaged and the loss becomes permanent.
Stages of Gum Disease
1. Gingivitis
Gums are red, swollen, and bleed on brushing. No bone loss. Reversible within 1–2 weeks with good hygiene and professional cleaning.
2. Mild Periodontitis
Shallow pockets (3–4 mm) develop between the tooth and gum, and the bone starts losing density. Bleeding becomes more frequent.
3. Moderate Periodontitis
Deeper pockets (5–6 mm), noticeable gum recession, and greater bone loss. Teeth may become slightly mobile.
4. Severe Periodontitis
Pockets 7 mm or deeper, significant bone loss, gum abscesses, clear tooth mobility, and possible tooth loss.
Symptoms of Gum Disease
- Bleeding gums when brushing or flossing.
- Red, swollen, tender gums.
- Persistent bad breath not relieved by mouthwash.
- Gum recession making teeth look longer.
- Abscesses around teeth.
- Loose or shifting teeth.
- Metallic or bitter taste in the mouth.
Causes and Risk Factors
- Poor oral hygiene and plaque/tartar buildup.
- Smoking — multiplies risk 4–5 times.
- Uncontrolled diabetes.
- Hormonal changes (pregnancy, puberty, menopause).
- Certain medications (anti-epileptics, immunosuppressants, BP drugs).
- Vitamin C deficiency.
- Genetic predisposition.
- Chronic stress.
Diagnosis
The dentist uses a fine probe to measure pocket depth around each tooth and takes X-rays to assess bone density. This exam should be done at least once a year.
Treatment
For Mild Cases (Gingivitis)
- Professional cleaning in the clinic.
- Instruction on improved brushing and flossing technique.
- Short-term antibacterial mouthwash (chlorhexidine).
For Moderate to Severe Cases (Periodontitis)
- Scaling and root planing: deep cleaning below the gum line with specialized instruments, usually over several visits.
- Local or systemic antibiotics.
- Flap surgery: surgical access to deep pockets.
- Bone or gum grafts: to restore lost supporting tissue.
- Laser therapy: modern techniques to remove inflamed tissue and promote healing.
Medical tip: Bleeding gums are not normal and do not mean you're brushing too hard. They are usually a sign of inflammation that needs treatment before it progresses.
Prevention
- Brush twice daily for a full two minutes.
- Floss at least once a day.
- Use interdental brushes or a miswak if recommended.
- Quit smoking.
- Control blood sugar if you have diabetes.
- Visit the dentist for cleaning every 6 months.
- Eat a diet rich in vitamin C and calcium.
When to See a Specialist Urgently
See a dentist or periodontist immediately if you notice recurrent bleeding, swelling, tooth mobility, or an abscess. The longer treatment is delayed, the greater the permanent damage and the higher the cost.
