What Is Gum Recession?
Gum recession is the process where gum tissue wears away or pulls back from the tooth surface, exposing the underlying root.
Healthy teeth consist of two main anatomical sections. The crown is the visible part of the tooth covered by enamel, which is the hardest substance in the human body. The root comprises the lower portion of the tooth and anchors it into the jawbone. Cementum covers the root surface. Cementum is much softer than enamel.
The cementoenamel junction, abbreviated as CEJ, marks the specific boundary where the enamel of the crown meets the cementum of the root. Healthy gum tissue sits entirely above the CEJ, protecting the delicate root. When gums recede, the tissue drops below the CEJ. This leaves the soft cementum exposed to the oral environment, leading to sensitivity, decay risk, and aesthetic concerns.
Gingival recession is a highly prevalent oral health condition. According to the Journal of Periodontology, 88% of adults over 65 years old and 50% of adults aged 18 to 64 present with at least one site of gingival recession. The Australian Research Centre for Population Oral Health reports similar trends locally, noting that recession affects approximately 60% of Australian adults aged 45 and older.
What Causes Gums to Recede?
Seven primary factors cause gums to recede, ranging from bacterial infections to mechanical wear and genetic predispositions.
- Periodontal disease: Bacterial infection destroys gum tissue and the underlying alveolar bone holding gums in position. As bone recedes, gums follow. Periodontal disease represents the most common cause of gum recession. Patients requiring gum disease treatment frequently present with associated tissue loss.
- Aggressive tooth brushing: Brushing too hard or using a hard-bristled brush physically wears away gum tissue. The Journal of Clinical Periodontology states that aggressive brushing causes up to 30% of recession cases.
- Genetics and thin gum biotype: Some individuals possess naturally thin gum tissue that recedes more easily under stress. Approximately 15% of the population has a thin biotype, making them highly susceptible to gingival recession regardless of their oral hygiene habits.
- Teeth grinding or bruxism: Grinding flexes the tooth within its socket. This flexing stress concentrates at the neck of the tooth near the gum line. The pressure causes the enamel to chip away, creating abfraction lesions, and forces the gum tissue to recede. Patients benefit from grinding appliances to mitigate this mechanical force.
- Tobacco use: Smoking restricts blood vessels, reducing blood flow to the gums. This impaired circulation limits healing response and increases plaque accumulation. Smokers present with three times the risk of developing gum recession compared to non-smokers.
- Hormonal changes: Pregnancy, menopause, and menstrual cycles alter gum tissue sensitivity. Fluctuations in oestrogen levels make gum tissues more susceptible to inflammation and subsequent recession.
- Misaligned teeth: Crooked, crowded, or rotated teeth create areas where brushing and flossing prove difficult. Plaque accumulates in these inaccessible zones, gum inflammation develops, and localized recession follows along the misaligned tooth root. Straightening teeth with clear aligners eliminates these plaque traps.
Gum Recession Risk Factors
Understanding specific risk factors helps quantify the threat to your gum line. The table below details the primary risk factors, their impact level, and their clinical significance.
| Risk Factor | Impact Level | Why It Matters |
|---|---|---|
| Periodontal disease | Very High | Destroys supporting bone and soft tissue |
| Aggressive brushing | High | Mechanically wears away soft tissue |
| Smoking and tobacco | High | Impairs blood flow, reduces healing capacity |
| Teeth grinding | Moderate | Abfraction creates micro-damage at the neck of the tooth |
| Thin gum biotype | Moderate | Less tissue volume exists to withstand mechanical stress |
| Hormonal changes | Moderate | Increases gum tissue sensitivity and inflammatory response |
| Misaligned teeth | Low to Moderate | Creates hard-to-clean plaque traps leading to localised inflammation |
What Are the Symptoms of Gum Recession?
Symptoms of gum recession progress from mild sensitivity to visible root exposure and severe pain.
Patients experience symptoms across three distinct stages:
Early signs:
- Mild sensitivity to hot and cold temperatures.
- Teeth appear slightly longer than they previously did.
- A distinct notch or groove felt at the gum line when running a fingernail along the tooth surface.
Moderate signs:
- Visible root surface, which appears yellowish compared to the white enamel of the crown.
- Increased sensitivity to sweet and acidic foods and beverages.
- Gaps appearing between teeth near the gum line, commonly referred to as black triangles.
Advanced signs:
- Severe, persistent sensitivity that disrupts normal eating and drinking.
- Root decay, presenting as cavities or structural breakdown on the exposed root surfaces.
- Loose teeth, which indicates advanced underlying bone loss.
- Noticeable gum line asymmetry, where gums appear significantly lower on certain teeth compared to adjacent ones.
Is Gum Recession Reversible?
Gum tissue does not grow back once it has receded, but gum grafting surgery restores the gum line.
Gum tissue lacks the regenerative capacity of skin. Once the gingival tissue and the underlying alveolar bone are lost, the human body does not replace them spontaneously. Non-surgical treatments manage symptoms, protect the exposed cementum, and halt the progression of tissue loss.
The primary goal of periodontal intervention is to stop further recession, protect the exposed root surface from decay and abrasion, and rebuild the protective gum barrier. Rebuilding the gum line requires surgical intervention. Periodontists perform gum grafting procedures to transplant tissue from another area of the mouth, successfully covering the exposed root and restoring the anatomical gum line.
How Do We Diagnose Gum Recession at Albany Creek Dental?
Dr Harvey Sandhu BDS diagnoses gum recession using a 5-step clinical process involving visual examinations, periodontal probing, and digital imaging.
As a QIP Accredited practice with over 30 years of experience serving the local community, Albany Creek Dental utilizes a comprehensive diagnostic protocol to assess tissue loss accurately.
- Visual examination: Dr Sandhu measures the exact position of the gum relative to the cementoenamel junction. This identifies which teeth present with recession and determines the extent of tissue loss in precise millimetres.
- Periodontal probing: A specialised dental probe measures the pocket depths around the circumference of each tooth. Pocket depths exceeding 3 millimetres indicate underlying gum disease driving the recession.
- Miller Classification: The diagnostic team rates the recession using the Miller Classification system. Class I indicates mild recession with no bone loss. Class IV indicates severe recession accompanied by bone loss and potential tooth rotation.
- Digital X-ray: Clinical staff utilise digital X-rays to assess the bone levels between the teeth. Radiographic bone loss confirms periodontal disease as the primary aetiology for the receding gum tissue.
- Bite analysis: The dentist examines the bite for specific wear patterns and abfraction lesions. This analysis identifies teeth grinding or clenching habits contributing to the mechanical failure of the gum tissue.
What Are the Treatment Options for Gum Recession?
Treatment options for gum recession include desensitising agents, composite bonding, and surgical gum grafting, determined by the underlying cause and Miller classification.
Addressing receding gums requires a tailored approach based on the severity of the tissue loss, the aesthetic concerns of the patient, and the primary aetiology driving the condition.
Desensitising Treatment
Dentists apply fluoride varnish or specialised desensitising agents directly to the exposed root surfaces. This treatment reduces sensitivity by blocking the microscopic dentinal tubules that connect the tooth surface to the internal nerve. Patients require reapplication every 3 to 6 months. Cost ranges from $80 to $150 per application. This intervention suits patients with mild recession experiencing sensitivity but presenting with no major aesthetic concerns.
Composite Bonding
The dentist applies tooth-coloured composite resin over the exposed root surface. This restoration covers the sensitive root, reduces discomfort, and improves visual symmetry by blending with the natural tooth colour. Composite bonding does not add new gum tissue. Instead, it fills the abrasive notch at the gum line. Cost ranges from $200 to $350 per tooth. This option treats moderate recession presenting with visible notching and persistent sensitivity. Learn more about dental fillings.
Gum Grafting Periodontal Surgery
A periodontist takes tissue from the patient’s palate or utilises donor material, known as AlloDerm, and places it over the recession site. This surgical procedure restores the natural gum line, completely covers the exposed roots, and prevents further recession. Healing requires 2 to 4 weeks. Cost ranges from $600 to $1,200 per tooth. Periodontists recommend this approach for advanced recession, significant aesthetic concerns, or progressive tissue loss despite active cause management.
Orthodontic Treatment
Straightening misaligned teeth using clear aligners removes the hard-to-reach plaque traps contributing to localised inflammation and gum recession.
Occlusal Guard
A custom night splint prevents the excessive grinding forces responsible for abfraction lesions and subsequent gum recession. Explore our custom grinding appliances.

How Can You Stop Gum Recession from Getting Worse?
You stop gum recession from worsening by switching to a soft-bristled brush, correcting your brushing technique, and treating underlying oral health conditions.
Halting the progression of tissue loss requires strict adherence to the following actionable steps:
- Switch to a soft-bristled brush. Hard and medium bristles physically wear away gingival tissue. Soft bristles clean effectively without causing mechanical trauma to the delicate gum margin.
- Use the correct brushing technique. Hold the toothbrush at a 45-degree angle directly aimed at the gum line. Use gentle circular motions rather than aggressive back-and-forth scrubbing. An electric toothbrush equipped with a pressure sensor alerts the user when excessive force is applied.
- Floss daily. Dental floss removes plaque and bacteria from between the teeth where the toothbrush cannot reach. Plaque accumulation between teeth generates gum inflammation that accelerates the breakdown of gingival tissue.
- Address teeth grinding. A custom night splint eliminates the destructive grinding forces that cause abfraction lesions and force the gums to recede. Explore our grinding appliances to protect your teeth while sleeping.
- Quit smoking. Tobacco use impairs blood flow to the gum tissues and limits natural healing responses. Smokers present with three times the risk of periodontal destruction and tissue loss compared to non-smokers.
- Treat gum disease promptly. Active periodontal infection continually destroys the jawbone supporting your teeth. Professional gum disease treatment halts bacterial bone loss and stabilises the receding gum line.
- Attend 6-monthly check-ups. Early signs of gum recession remain undetectable without professional clinical measurement. Regular appointments allow your dentist to track millimetre progression accurately over time. Book an appointment through our comprehensive dental check-ups to monitor your gum health.
Frequently Asked Questions
Can gums grow back after receding?
No, gums do not grow back after receding. Once gingival tissue recedes, it lacks the biological capacity to regenerate spontaneously. Gum grafting surgery restores the gum line using tissue from the palate or donor material. Desensitising treatments and composite bonding manage symptoms without adding new tissue. Treatment focuses on halting progression and protecting exposed roots.
Is gum recession always caused by gum disease?
No, gum recession is not always caused by gum disease. Periodontal infection causes approximately 50% of recession cases. The remaining cases result from aggressive tooth brushing, genetic predisposition, teeth grinding, tobacco use, hormonal fluctuations, and misaligned teeth. A comprehensive dental examination determines the specific aetiology for each patient.
How fast does gum recession progress?
Gum recession progresses slowly over years in most cases, advancing 0.1 to 0.5 millimetres annually. Aggressive tooth brushing, untreated periodontal disease, or severe teeth grinding accelerate this progression. Millimetre measurements recorded at each routine check-up track the exact rate of tissue loss. Rapid recession occurring over a few weeks indicates acute infection or acute physical trauma.
Does gum recession cause tooth loss?
Severe untreated gum recession leads to bone loss and loose teeth. However, early clinical intervention halts disease progression. Most recession cases stabilise completely with proper management and targeted treatment, preventing tooth loss. Advanced cases presenting with significant alveolar bone loss require periodontal surgery or tooth extraction.
Is gum grafting painful?
Gum grafting produces no pain during the procedure and mild discomfort for 3 to 5 days post-operation. Surgeons use local anaesthetic to numb the surgical site completely. Patients manage post-operative discomfort with standard paracetamol or ibuprofen. The donor site located on the palate heals completely within 2 weeks. Most individuals return to normal daily activities within 48 hours.
Can I brush receding gums back into place?
No, you cannot brush receding gums back into place. Brushing harder physically irritates the remaining tissue and actively worsens the recession. A soft brush combined with gentle circular motions prevents further mechanical damage. Once gingival tissue is lost, only surgical grafting restores the anatomical gum line.
