Receding Gums: Causes and How to Stop the Progression

What recession is

Gum recession is the exposure of tooth root as the gumline pulls back. It often looks like teeth appearing longer, and exposes cementum and dentin — not enamel — which is why it usually causes sensitivity.

Causes

Aggressive brushing

The most common cause in otherwise healthy adults. Hard bristles, horizontal scrubbing, or heavy pressure abrade the gum over years.

Periodontal disease

Bacterial inflammation destroys gum and bone attachment. Recession here is a symptom of a bigger issue.

Orthodontic movement

Teeth moved outward in narrow bone can have insufficient gum coverage at the new position.

Genetics

Some people have naturally thin "biotype" gum tissue — prone to recession even with perfect care.

Teeth grinding

Lateral forces from grinding can cause gum recession on facial surfaces of premolars.

Tongue or lip piercings

Repetitive trauma to adjacent gum.

Smoking

Reduces gum blood supply; accelerates recession.

Can gum grow back?

Not spontaneously. Once the attachment is lost, it doesn't regenerate without surgical intervention. However:

• Passive healing: gums can "tighten up" if you stop the cause and improve hygiene
• Connective tissue graft: surgical procedure that adds tissue back
• Pinhole technique: minimally invasive gum repositioning
• Guided tissue regeneration: with grafting material

Stop the progression — protocol

Immediate

1. Switch to extra-soft toothbrush (or electric with pressure sensor)
2. Gentle technique only — no scrubbing
3. Check for gum disease — deep cleaning if present
4. Nightguard if grinding is a factor
5. Stop smoking

Sensitive in the recessed area?

• Fluoride varnish at hygiene visits
• Sensodyne daily
• Consider desensitising resin bonded to the exposed root

Progressive or severe?

• See a periodontist for a grafting consultation
• A connective tissue graft can restore 2–4 mm of gum coverage per area
• Multiple sites can be treated in one surgery

Surgical options

Connective tissue graft

Gold standard. Tissue taken from the palate (or donor source) and sutured over the receded area. Healing: 2–3 weeks. Success rate: 85–95% of coverage in well-selected cases.

Cost in Dubai: AED 2,500–5,500 per tooth site.

Pinhole surgical technique

Minimally invasive. Small hole made above the receded area; gum loosened and repositioned. No cutting. Less discomfort, faster healing.

Cost in Dubai: AED 2,500–6,500 per quadrant.

Free gingival graft

When you need more attached gum thickness, not just coverage. Thicker tissue from the palate is transplanted.

Daily care for recessed areas

• Ultra-soft brush
• Avoid hard lateral scrubbing
• Fluoride rinse daily
• Professional cleaning every 3–4 months
• Interdental brushes rather than string floss in recessed areas
• Nightguard if grinder

The check-up questions

Ask your dentist at every visit:

• Is my gum line changing?
• Am I developing any new recessed areas?
• Is my brushing technique contributing?
• Should I see a periodontist?

Early consultation with a periodontist is often cheaper than waiting until multiple teeth need grafting.
