What Is Gum Recession?
Gum tissue plays a protective role by covering the roots of the teeth and helping to seal the underlying bone from bacteria and external irritants. When this tissue recedes, the root surfaces become exposed. Unlike the crown of the tooth, the root is not covered by hard enamel — instead, it is protected by a thinner layer called cementum, which is more vulnerable to wear, decay, and temperature sensitivity.
Gum recession is closely associated with periodontal disease, one of the most common oral health conditions in the UK. Chronic gum inflammation can damage the attachment between the gum and the tooth, leading to gradual tissue loss. However, recession can also occur in the absence of active gum disease — for example, as a result of brushing technique, bite-related forces, or anatomical factors.
It is important to understand that gum recession does not mean inevitable tooth loss. With appropriate professional assessment and management, the condition can often be stabilised and the exposed areas protected. Early identification provides more options for conservative care.
Common Causes of Receding Gums
Gum recession can develop for a variety of reasons, and more than one factor may be involved. A professional evaluation is the most reliable way to identify the specific cause and guide appropriate management.
Periodontal Disease
Gum disease is one of the most common causes of recession. Bacterial infection and chronic inflammation can damage the gum tissue and the bone supporting the teeth, leading to gradual tissue loss.
Aggressive Brushing
Brushing with excessive force or using a hard-bristled toothbrush can wear away gum tissue over time, particularly along the gum line. This is sometimes referred to as toothbrush abrasion.
Teeth Grinding (Bruxism)
Habitual grinding or clenching places excessive lateral forces on the teeth, which can contribute to gum recession by stressing the supporting tissues around the teeth.
Bite Imbalance
When the teeth do not meet evenly during biting and chewing, the resulting uneven forces may place additional stress on certain areas of gum tissue, contributing to localised recession.
Genetic Factors
Some individuals are more susceptible to gum recession due to inherited characteristics such as thinner gum tissue or a predisposition to periodontal disease, even with good oral hygiene.
Smoking
Tobacco use reduces blood flow to the gums, impairs healing, and increases the risk of periodontal disease — all of which can contribute to gum recession over time.
Signs and Symptoms
Gum recession often develops gradually, and early changes can be subtle. The following signs may indicate that the gum tissue has started to recede, though a dental examination is needed to confirm the extent and cause.
Teeth Appearing Longer
As the gum tissue recedes, more of the tooth surface becomes visible. You may notice that your teeth appear longer than they used to, or that the proportions of your smile have changed.
Sensitivity to Hot or Cold
Exposed root surfaces lack the protective enamel that covers the tooth crown, making them more susceptible to temperature changes. This can result in sharp, short-lived discomfort when eating or drinking.
Visible Root Surfaces
In more noticeable cases of recession, the yellowish root surface of the tooth may become visible below the gum line, particularly on the front teeth or along the outer surfaces.
Gum Line Changes
The gum line may appear uneven or notched, with the tissue sitting at different levels around individual teeth. These changes may develop gradually and can be difficult to notice without professional examination.
Occasional Tenderness
The area around receding gums may feel tender or sensitive to touch, particularly during brushing. Some patients also notice mild discomfort when pressure is applied near the affected gum tissue.
Why Professional Assessment Is Important
Gum recession may be a visible sign of an underlying periodontal condition that requires professional management. Without assessment, it is difficult to determine whether recession is localised and stable, or part of a broader pattern of gum disease that may continue to progress.
Exposed root surfaces are more vulnerable to decay than enamel-covered areas, and they may also be more susceptible to wear and sensitivity. Identifying recession early allows your dental team to implement protective measures before these complications develop.
During a periodontal assessment, your dentist or hygienist may carry out gum measurements and, where indicated, dental imaging to evaluate bone levels around the teeth. These findings help determine the extent of recession and guide the development of a tailored management plan. Early management is generally more conservative and helps reduce the risk of further tissue loss.
Professional Management and Supportive Treatment
The management of gum recession depends on its severity, the underlying cause, and the individual needs of the patient. Treatment aims to protect exposed areas, stabilise the condition, and reduce the risk of further recession. Your dental team may recommend one or more of the following approaches:
Professional Hygiene Treatment
Thorough removal of plaque and calculus from the tooth surfaces and along the gum line. This aims to reduce bacterial load, address any underlying gum inflammation, and create a healthier environment for the gum tissue.
Periodontal Therapy
Where deeper periodontal pockets are present, root surface debridement may be recommended to clean below the gum line and help stabilise gum attachment, reducing the risk of further recession.
Desensitising Strategies
Professional application of desensitising agents to exposed root surfaces may help reduce the transmission of stimuli to the tooth nerve, providing relief from temperature-related discomfort.
Fluoride-Based Protective Care
Concentrated fluoride varnish applied by your dentist aims to strengthen exposed surfaces and may help reduce sensitivity. This protective approach can be repeated at regular intervals as part of ongoing care.
Composite Bonding for Exposed Roots
In appropriate cases, tooth-coloured composite resin may be applied to cover exposed root surfaces. This can help protect the area from sensitivity and improve the appearance of the affected teeth.
Specialist Gum Graft Consultation
In selected cases of more advanced recession, referral to a specialist periodontist for gum graft assessment may be discussed. This procedure involves placing tissue over the exposed root area to restore gum coverage.
Treatment outcomes depend on individual circumstances. Your dentist will discuss what can reasonably be expected based on the specific findings and the approach recommended.
Professional Assessment for Gum Recession
Professional periodontal evaluation helps determine the extent of gum recession and supports the development of a tailored care plan. Whether you have noticed increased sensitivity, changes in your gum line, or have been advised that recession may be present, assessment is the first step toward appropriate management.
Depending on the findings, your dental team may recommend gum disease treatment to address any underlying periodontal condition, general dentistry for routine assessment and preventive care, or composite bonding to help protect exposed root surfaces where appropriate. If you are experiencing significant discomfort, our emergency dental assessment service is also available.
Assessment and management of receding gums are available at our London clinics. You can attend our South Kensington dental clinic or our City of London clinic near St Paul's for a professional periodontal review.
Can Receding Gums Grow Back?
Gum tissue that has been lost through recession does not naturally regenerate. Unlike some tissues in the body, the gums cannot regrow once they have receded from the tooth surface. This is one of the reasons why early identification and management are particularly valuable — preserving existing gum tissue is more effective than attempting to restore what has been lost.
Treatment therefore focuses on stabilising the condition, protecting exposed root surfaces from sensitivity and decay, and addressing any underlying factors that may be contributing to ongoing recession. Measures such as improved brushing technique, professional hygiene treatment, and protective applications can all play a role in this process.
In selected cases where recession is more advanced or causing significant concern, specialist procedures such as gum grafting may be discussed. These involve placing soft tissue over the exposed root area to help restore gum coverage. However, suitability for such procedures is assessed on an individual basis, and outcomes can vary depending on the location and extent of the recession.
Preventing Further Gum Recession
While existing gum recession cannot be reversed through home care alone, the following measures can help reduce the risk of further tissue loss and support long-term gum health:
- Use a soft-bristled toothbrush and gentle, circular brushing motions to avoid placing excessive pressure on the gum tissue
- Attend regular professional hygiene appointments at the frequency recommended by your dental team
- If you have been diagnosed with gum disease, follow your prescribed periodontal care plan to help manage the condition
- Discuss teeth grinding with your dentist — a custom-made protective appliance may be recommended to reduce forces on the teeth and gums
- Attend routine dental check-ups so that early signs of recession can be identified and monitored over time
- If you smoke, consider seeking support for cessation — your dental team or GP can provide guidance on available options
