Receding Gums: Causes, Symptoms, and Treatment

Part of the Gum Health guide in the Oral Health section.

What do receding gums look and feel like?

The crown—the part of a tooth normally visible above the gumline—is covered by hard enamel. A tooth root has a different protective covering and can become exposed when the gum margin moves down or away. Because exposed root surfaces are more vulnerable to sensitivity and decay than enamel-covered crowns, recession is more than a cosmetic change.

Possible signs include:

• one tooth appearing longer than nearby teeth;
• a visible yellowish or darker root surface near the gumline;
• a notch or groove where the tooth meets the gum;
• sensitivity to cold, heat, sweets, touch, or brushing;
• a change in the symmetry of the gumline;
• spaces or dark “triangles” becoming more visible between teeth;
• food collecting in a new space; or
• redness, bleeding, swelling, bad breath, or tooth movement when gum disease is also present.

Recession may involve one tooth, several teeth, or much of the mouth. It can progress slowly enough that a person notices only after comparing older photographs or being shown measurements during an examination.

If one small area is painful or bleeds, recession may not be the only issue. Arrange an examination if the symptom persists or recurs.

Why do gums recede?

Gum recession is a finding, not a diagnosis by itself. More than one factor may be involved.

Periodontitis

Periodontitis destroys the connective tissue and bone supporting teeth. As this support is lost, gums may pull away, periodontal pockets may deepen, and roots may become exposed. Bleeding, tartar, persistent bad breath, tooth mobility, or changes in the bite make a periodontal assessment particularly important.

Forceful or abrasive cleaning

Scrubbing with excessive pressure, using a hard-bristled brush, or repeatedly brushing sideways at the gumline can traumatize susceptible tissue. More pressure does not clean plaque more effectively. However, do not assume brushing is the cause and stop cleaning the area; plaque-related inflammation can also cause recession. A dental professional can help distinguish the pattern and demonstrate a gentler technique.

Naturally thin gum tissue and local anatomy

Some people have a thinner gum “phenotype,” which is less resistant to recession. The position of a tooth in the jaw, the pull of a frenum or nearby muscle attachment, and the shape of the surrounding tissues can influence risk. Recession may also become noticeable next to a missing tooth or in an area with limited tissue support.

Plaque and tartar

Persistent plaque inflames the gumline. Hardened tartar creates a rough surface that is difficult to keep clean and must be removed professionally. Gingivitis itself does not always mean attachment loss, but unresolved inflammation should be treated before it progresses or complicates a vulnerable area.

Dental factors

Crowding, a tooth positioned toward the edge of the supporting bone, or an overhanging restoration can make an area more vulnerable or difficult to clean. Anatomy and inflammation need to be considered together, so treatment planning is individualized.

Tobacco and healing factors

Smoking and other tobacco use increase the risk and severity of periodontal disease and can impair healing. Diabetes and medicines that affect the mouth may also change the overall care plan. Share your complete health and medicine history with the dental team.

Is gum recession serious?

Small, stable recession is not always an emergency. It deserves assessment because exposed roots can become sensitive, wear down, or develop root decay. The appearance may also signal active periodontal disease, traumatic cleaning, or a local problem that will continue unless its cause is addressed.

Contact a dentist promptly if recession is new, progressing, affecting several teeth, or accompanied by bleeding, swelling, pus, persistent bad breath, pain when chewing, or tooth movement. A suddenly changing gumline should not be treated as a normal part of aging.

How dentists evaluate receding gums

The examination is designed to identify both the amount of recession and its cause. A dentist or periodontist may:

1. measure the position of the gum margin and the periodontal pockets;
2. check for plaque, tartar, bleeding, inflammation, and loss of attachment;
3. inspect the exposed root for decay, wear, or a non-cavity notch;
4. assess tooth position, gum thickness, frenum pull, restorations, and the bite;
5. ask about brushing technique, tobacco, sensitivity, medical conditions, medicines, and prior orthodontic or periodontal treatment; and
6. use dental X-rays when bone loss, decay, or another underlying problem is suspected.

Photographs or recorded measurements can help show whether an area is stable or changing. Sensitivity alone cannot prove recession because cavities, cracks, worn fillings, and enamel wear can produce similar symptoms.

Treatment options for receding gums

Treatment is matched to the cause, symptoms, progression, and amount of supporting tissue. Not every case needs surgery.

Correct the cause and monitor the site

For mild, stable recession, the first step may be controlling plaque, using a gentle brushing technique, choosing appropriate interdental tools, and monitoring measurements. A soft-bristled brush should be guided along the gumline with light pressure; your dentist or hygienist can demonstrate a method suited to your dexterity and tooth arrangement.

If tartar or gum disease is present, professional periodontal treatment comes first. A rough restoration may need adjustment or replacement, while tobacco cessation and health-condition management can support healing.

Reduce root sensitivity and decay risk

Desensitizing toothpaste can reduce sensitivity over repeated use; it is not an instant repair and it does not move the gum back. A dentist may recommend professional fluoride, a protective coating, or bonding depending on the root surface, sensitivity, and decay risk. Persistent pain needs evaluation before it is labeled “sensitive teeth.”

Restore a worn or damaged root surface

When recession occurs alongside a non-cavity notch or root decay, a restoration may protect the area or improve its shape. The dentist and periodontist may coordinate restorative and gum treatment because covering the wrong part of the root can affect the final result.

Gum grafting or other root-coverage surgery

A periodontist may recommend a soft-tissue graft when recession is progressing, the tissue is very thin, the root is sensitive, cleaning is difficult, or root coverage would improve protection or appearance. One common approach uses a small amount of the patient’s own tissue, often from elsewhere in the mouth, to thicken the gum or cover part of the exposed root. Other materials or flap techniques may be appropriate in selected cases.

Root coverage is not guaranteed. Results depend on the recession pattern, bone and tissue between teeth, tooth position, smoking, plaque control, and healing. The gum may become thicker and more resistant even when the entire exposed root cannot be covered. Discuss expected coverage, discomfort, donor-site care, alternatives, and cost before surgery.

What you can safely do at home

• Brush twice daily with fluoride toothpaste and a soft-bristled brush.
• Use light pressure whether you choose a manual or powered brush, and ask a dental professional to check your technique if you routinely press too hard.
• Clean between the teeth every day with floss or appropriately sized interdental brushes recommended by your dental professional.
• Spit out excess fluoride toothpaste after brushing rather than immediately rinsing it all away.
• Use desensitizing toothpaste as directed if your dentist agrees that exposed root sensitivity is the cause.
• Avoid tobacco.
• Keep dental and periodontal review appointments so changes can be measured.

Do not stop cleaning a receded area because it feels tender. Instead, ask how to clean it with less trauma. Do not try to make gums “grow back” with forceful massage, concentrated peroxide, essential oils, aspirin, or abrasive powders. These can irritate or burn tissue and delay appropriate care.

Prevention: reducing the chance of further recession

Not every anatomical risk can be changed, but progression may be reduced by:

• removing plaque gently and consistently rather than scrubbing;
• having your brushing pressure and interdental technique checked;
• treating bleeding gums and periodontal disease early;
• keeping professional cleaning and examination intervals based on your risk;
• addressing areas where food repeatedly traps between teeth;
• avoiding tobacco;
• arranging periodontal assessment before cosmetic treatment if the gumline is thin or already receding.

When to seek urgent help

Routine recession is rarely a medical emergency, but the symptoms around it can be. Seek an urgent dental appointment for severe pain, a swollen gum, pus, a bad taste associated with swelling, fever, sudden tooth looseness, or rapidly worsening symptoms. These can suggest a gum abscess or dental infection rather than simple recession.

Seek emergency medical care if swelling makes it hard to breathe, swallow, or speak; spreads toward an eye or affects vision; involves much of the mouth, face, or neck; or severely limits mouth opening.

Frequently asked questions

Can receding gums grow back naturally?

No. Once the gum margin has receded, it does not predictably return to its earlier position on its own. Treatment can remove the cause, protect the root, help stabilize the area, and—in selected cases—cover some of the root surgically.

Does gum recession always mean gum disease?

No. Periodontitis is an important cause, but forceful brushing, thin tissue, local anatomy, tooth position, and other factors may contribute. An examination is the safest way to distinguish them.

Should I stop using an electric toothbrush?

Not automatically. Either a manual or powered toothbrush can be used gently. Pressure, technique, bristle condition, and placement matter more than simply choosing one type. Ask a dental professional to watch your technique if recession is progressing.

What toothpaste helps receding gums?

Fluoride toothpaste helps protect exposed roots from decay. A desensitizing fluoride toothpaste may reduce sensitivity over time. Toothpaste cannot regrow lost gum, and highly abrasive products can make root wear or sensitivity worse.

Do all receding gums need a graft?

No. Stable areas without significant symptoms may be monitored after the cause is controlled. Grafting is considered when tissue needs strengthening, recession is progressing, the root is vulnerable or sensitive, or root coverage is a realistic goal.

Can a receding gum make a tooth fall out?

Recession alone does not always mean a tooth is loose. Recession caused by advanced periodontitis may occur with supporting bone loss, which can threaten the tooth. Mobility, new spacing, or a bite change needs prompt assessment.

Can mouthwash reverse recession?

No. Mouthwash cannot replace lost tissue or remove tartar below the gumline. A dentist may recommend a rinse for another reason, but it is an adjunct rather than a root-coverage treatment.
