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 (see tooth sensitivity).

Causes

Aggressive brushing

A 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 (see gum disease stages and treatment).

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 meticulous care.

Teeth grinding

Heavy grinding may contribute to recession on the outer surfaces of premolars, although the evidence is mixed.

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 (see how to brush your teeth)
3. Check for gum disease — deep cleaning if present (see deep cleaning)
4. Nightguard if grinding is a factor
5. Stop smoking

Sensitive in the recessed area?

• Fluoride varnish at dental visits
• A sensitivity toothpaste daily
• Consider desensitising resin bonded to the exposed root

Progressive or severe?

• Ask about a grafting assessment; complex grafting is often carried out by a periodontist on referral
• A connective tissue graft can restore a meaningful amount of coverage in well-selected cases
• Multiple sites can often be treated in one procedure

Surgical options

Connective tissue graft

The most widely used and studied technique. Tissue taken from the palate (or a donor source) is sutured over the receded area. Healing: 2–3 weeks. High rates of root coverage are reported in well-selected cases.

Pinhole surgical technique

Minimally invasive: the gum is loosened through a small entry hole and slid down over the root, without scalpel incisions or stitches. Many patients report less discomfort afterwards, though long-term data are more limited than for grafting.

Free gingival graft

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

Fees depend on the technique and the number of sites and are quoted after assessment; see pricing.

What a gum graft involves

A gum graft is done under local anaesthetic and takes about 60 to 90 minutes per site. For a connective tissue or free gingival graft, a small piece of tissue is taken from the palate, or a donor material is used, then placed over the exposed root and secured with fine stitches. Expect about two weeks of soft food and gentle cleaning around the area, with discomfort that ranges from minimal to moderate. When several teeth are treated, each site is usually charged separately, so ask for a per-site quote.

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?
• Would I benefit from a periodontal referral?

Early assessment is usually simpler, and cheaper, than waiting until multiple teeth need grafting. Gum care is part of gum disease treatment.

Common questions

Why do gums recede?

Usually several factors combine. Brushing too hard is a common cause; others include gum disease, tooth grinding, genetics and, occasionally, tooth movement during orthodontic treatment. To limit further recession, use a soft brush with a gentle technique and have gum disease treated early. Where recession is severe, gum grafting can cover exposed roots.

Can braces or Invisalign cause gum recession?

They can, though significant recession is uncommon. Recession during orthodontics happens when teeth are moved beyond the bone that houses them, when the patient has a naturally thin gum biotype, when hygiene slips during treatment, or when recession was already present. Mild recession affects a minority of orthodontic patients. Prevention is a periodontal assessment before treatment, conservative movements for thin-biotype patients, and strict hygiene with gentle brushing throughout. If recession does develop it is usually addressed after treatment, sometimes with a connective tissue graft.

Can veneers fix receded gums?

No. A veneer covers the tooth surface but does not restore lost gum tissue, and placing one over active recession can leave the margin exposed (see do veneers damage teeth?). Treat the recession first, often with a gum graft, and reassess once tissue is stable. In some cases a combined plan (graft, then a veneer to refine shape or colour) makes the area less noticeable.

What are the treatment options for gum recession in older adults?

Treatment depends on how far recession has progressed and whether it causes symptoms. Mild cases need a soft-bristle brush and gentle technique to stop further loss. Where exposed roots are sensitive, bonding over the root surface can relieve it. For severe recession, gum grafting rebuilds tissue, and the pinhole technique offers a less invasive surgical alternative. Age itself does not rule out any of these options (more in dental care after 60).

Practical decision guide

General dental decisions should preserve healthy tooth structure whenever possible. A good plan moves from diagnosis to the least-invasive durable treatment, then to prevention so the same problem does not repeat.

Check this first

• X-rays, pulp vitality, crack lines, gum pocketing, bite contacts, and how much natural tooth remains.
• Whether the problem is active disease, old restoration failure, trauma, wear, or a cosmetic concern.
• Whether a filling, onlay, crown, root canal, extraction, or monitoring is the right next step.

When to book sooner

• Pain wakes you at night, lingers after hot or cold, hurts on biting, or comes with swelling.
• A crown or filling falls out, a tooth cracks, or a sharp edge is cutting the tongue or cheek.
• You notice pus, fever, spreading swelling, or difficulty opening, swallowing, or breathing.

Questions to ask at the appointment

• What is the diagnosis, and what evidence supports it on the x-ray or clinical exam?
• What is the smallest treatment that solves the problem predictably?
• What failure signs should I watch for after treatment?

Dubai patient note

If insurance is involved, ask whether pre-approval is required, what codes will be submitted, and what alternatives are clinically acceptable if coverage is limited.
