Introduction

Noticing that your teeth look longer than they used to, or that your gum line seems to have shifted, can be unsettling. For many people, the realisation that their gums may be receding comes gradually — perhaps through increased sensitivity when drinking something cold, or noticing a visible change in the way a tooth meets the gum. For others, a dental professional may point it out during a routine check-up before it has become noticeable at all.

Gum recession is a relatively common finding across all age groups in the UK, though how significant it is and what — if anything — needs to be done about it depends greatly on the individual circumstances. The causes, the degree of change, and the most appropriate response can all vary considerably from person to person.

This article explains what receding gums are, why gum recession can develop, what changes you might notice, what risks are associated with it, and how a dental professional may approach assessment and management. It is intended as educational information and does not replace advice from a qualified dental professional who can assess your specific situation.

Quick Answer: What Are Receding Gums?

Receding gums occur when the gum tissue surrounding a tooth gradually moves downward (or upward on upper teeth), exposing more of the tooth surface or its root. This can result from gum disease, certain brushing habits, tooth position, or other individual factors. Because causes vary, so do treatment approaches — making a professional dental assessment the appropriate starting point for anyone who has noticed a change in their gum line.

---

What Are Receding Gums?

The gum tissue — known clinically as the gingiva — normally forms a protective seal around each tooth, meeting the tooth at a point called the gum line. When this tissue gradually moves away from its original position, exposing a greater length of tooth or the underlying root surface, this is referred to as gum recession.

The gum line is not fixed. Over a lifetime, some degree of change is common, and minor recession does not automatically indicate a serious problem. However, when recession is noticeable, progressing, or accompanied by other symptoms, understanding why it is happening becomes important — both for protecting oral health and for deciding whether any treatment is appropriate.

Gum recession can affect a single tooth, several teeth in one area, or teeth across multiple parts of the mouth, depending on the contributing cause.

---

What Causes Gums to Recede?

Gum recession rarely has a single universal cause. Instead, various factors — individually or in combination — can contribute to the gradual loss of gum tissue position. Understanding the likely cause in any individual case is an important part of deciding how best to manage it.

Gum Disease (Periodontal Disease)

One of the more commonly discussed associations with gum recession is gum disease, particularly in its more advanced form, known as periodontitis. When plaque — the soft bacterial film that forms on teeth — is not adequately removed through regular oral hygiene, it can irritate the gum tissue and, over time, trigger an inflammatory response. In periodontitis, this inflammation can affect the supporting structures of the teeth, including the bone and gum tissue, potentially leading to recession.

Not all gum recession is caused by periodontal disease, but where gum disease is present and untreated, recession may be one of its consequences. The NHS recognises gum disease as a significant oral health concern, and early assessment can help establish whether it is a contributing factor.

Toothbrushing Habits and Technique

It may seem counterintuitive, but brushing too vigorously, too frequently, or with an unsuitable technique can, over time, contribute to gum recession — particularly at the margins where the brush meets the gum line. Abrasive brushing does not remove plaque more effectively than gentle brushing; research suggests that appropriate technique and consistency are more relevant than pressure. Using a medium or hard-bristled toothbrush may increase the risk of gum and tooth surface wear in some individuals.

This type of recession is sometimes localised — affecting teeth that are more exposed to direct brushing pressure, such as the outer surfaces of the upper canines or premolars.

Tooth Position and Anatomy

The natural position of a tooth within the jaw can influence the thickness and coverage of gum tissue around it. Teeth that sit outside the natural arch, or that have very thin overlying bone, may be more prone to recession — sometimes regardless of brushing habits or gum health. This is a factor that varies considerably between individuals.

Individual Gum Tissue Characteristics

The thickness and type of gum tissue around teeth varies between individuals. Those with naturally thinner gum tissue may be more susceptible to recession from relatively minor contributing factors. This is sometimes referred to as a "thin gingival biotype" in clinical contexts.

Smoking and Tobacco Use

Tobacco use — in any form — is associated with reduced gum tissue health. It can mask the signs of gum inflammation, impair the gum tissue's ability to respond appropriately, and is recognised as a significant risk factor for periodontal disease. People who smoke may be at greater risk of gum recession and may also respond less predictably to certain treatments.

Orthodontic Treatment

Movement of teeth during orthodontic treatment can sometimes affect the gum tissue, particularly when teeth are moved outside the natural bone envelope. This is not inevitable, but it is a factor that orthodontists consider when planning treatment. Where recession is noticed during or after orthodontic care, dental review is advisable.

Oral Habits and Localised Trauma

Certain habits — including nail biting, pen chewing, or the regular use of objects that contact the gum margin — can cause localised gum irritation or recession over time. Similarly, localised trauma from ill-fitting dental appliances or other factors may contribute in some cases.

Other Contributing Factors

Additional factors that may be relevant in some individuals include systemic health conditions, certain medications, and genetic predisposition. A thorough dental and medical history is part of any comprehensive assessment.

What Are the Signs of Gum Recession?

Gum recession does not always cause obvious discomfort, particularly in its earlier stages. Common signs that may indicate the gum line has changed include:

• Teeth appearing longer than before — as the gum tissue moves, more of the tooth surface becomes visible
• A visible notch or step at the gum margin — some people notice a distinct line where the tooth surface changes character
• Exposed tooth roots — root surfaces look and feel slightly different to the enamel-covered portion of the tooth; they may appear more yellow or feel rougher to the tongue
• Increased tooth sensitivity — particularly to cold, hot, sweet, or acidic foods and drinks; root surfaces do not have the protective enamel layer that covers the crown of the tooth, so exposed roots can be more sensitive
• Changes around one tooth — recession is sometimes localised, affecting a single tooth rather than spreading across the whole mouth
• Changes to the feel of the gum margin — some people notice the area feels different when running their tongue along their gum line

Not all of these signs will be present in every case, and some can have causes unrelated to recession. If you have noticed changes to your gum line or unexplained tooth sensitivity, a dental assessment can help establish what is happening.

Can Receding Gums Cause Problems?

In many cases, stable and mild recession causes few significant problems beyond cosmetic concern. However, where recession is more pronounced, progressing, or accompanied by an underlying cause that is not being managed, several complications may develop over time.

Tooth Sensitivity

Exposed root surfaces lack the hard enamel layer that protects the crown of the tooth. This can make affected teeth more sensitive to temperature changes, sweet foods, or dental instruments. The degree of sensitivity varies considerably between individuals.

Root Surface Vulnerability

Exposed root surfaces are not only more sensitive — they may also be more susceptible to dental decay (root caries) and surface wear. Root dentine is softer than enamel, making it more vulnerable to acid erosion and abrasion.

Difficulty Cleaning Certain Areas

Where recession creates changes in the shape of the gum margin, cleaning around the base of the tooth may become slightly more challenging. This does not necessarily mean effective cleaning is impossible, but it may require some adjustment of technique or the use of appropriate interdental cleaning aids.

Aesthetic Concerns

Many people who notice gum recession are primarily concerned about the appearance of their smile — particularly where teeth look noticeably longer than before. This is a valid concern, and where recession is causing significant cosmetic distress, there are treatment options that may be discussed with a dental professional.

Progression

Where an underlying cause — such as periodontal disease or traumatic brushing — remains unaddressed, recession may continue to progress. Monitoring and, where appropriate, intervention are important to help reduce the risk of further change.

---

What Treatments Are Available for Receding Gums?

The most appropriate management for gum recession depends on its cause, its extent, the condition of the surrounding gum and bone, and the individual's overall oral health. There is no single treatment that is suitable for every case.

Identifying and Addressing the Underlying Cause

The first step in managing gum recession is understanding why it has occurred. A dental assessment — which may include measurement of gum levels, assessment of gum health, and in some cases radiographic examination — helps establish the likely contributing factors and guides appropriate management.

Treating an underlying cause without addressing the recession itself is sometimes all that is needed for stable, non-progressive recession. Treating recession without identifying and managing the cause is unlikely to produce lasting results.

Improving Oral Hygiene Technique

Where brushing habits are contributing to recession, guidance on appropriate technique — including the use of gentle, circular or rolling movements, suitable pressure, and an appropriate toothbrush — may help reduce ongoing trauma to the gum margin. A dental professional or hygienist can provide personalised advice based on an individual's technique and the areas affected.

Professional Dental Cleaning and Periodontal Treatment

Where plaque accumulation, tartar (hardened plaque), or gum disease are contributing factors, professional cleaning may form part of management. In cases of periodontitis, more thorough periodontal treatment — which may involve cleaning below the gum line — might be recommended. This aims to address the underlying inflammation and reduce its effect on the supporting structures of the teeth.

Monitoring Stable Recession

Not all recession requires active intervention. Where recession is stable, the cause has been identified and managed, and there are no significant symptoms or risk factors, a dental professional may recommend monitoring rather than immediate treatment. This is a clinically appropriate and common approach.

Managing Tooth Sensitivity

Where exposed root surfaces are causing discomfort, various options may help reduce sensitivity. These can include desensitising toothpastes, fluoride applications, or — where appropriate — protective treatments applied to the root surface by a dental professional. Addressing sensitivity does not treat the underlying recession but can improve day-to-day comfort.

Gum Grafting and Surgical Procedures

In selected cases — where recession is significant, progressing, causing notable symptoms, or of cosmetic concern — a dental specialist may consider surgical options. Gum grafting, in which gum tissue is taken from another part of the mouth (or occasionally sourced from a tissue bank) and placed over the exposed root area, is an established procedure that can, in appropriate cases, improve gum coverage over exposed root surfaces.

Gum grafting is not suitable or necessary for all cases of recession. A specialist assessment is needed to determine whether surgical intervention is appropriate, what outcomes might realistically be expected, and what the procedure would involve. Results vary depending on the individual, the extent of recession, and other clinical factors.

Other surgical techniques may also be considered in certain circumstances, and these would be discussed as part of a specialist consultation.

Can Receding Gums Grow Back?

This is one of the most frequently asked questions about gum recession, and it is worth giving a clear and honest answer.

Gum tissue that has been lost through recession does not simply regenerate on its own. Unlike some other tissues in the body, the gum does not reliably grow back to its original position once it has receded — regardless of changes to brushing habits, home remedies, or over-the-counter products.

However, this does not mean nothing can be done. There are important distinctions to understand:

• Preventing further recession is often achievable by identifying and managing the contributing cause — whether that involves treating gum disease, adjusting brushing technique, or another appropriate intervention.
• Protecting exposed root surfaces through good oral hygiene, appropriate professional care, and sometimes protective treatments can help preserve the tooth despite the change in gum position.
• Surgically covering exposed root surfaces is possible in selected cases, as described above, though this is not appropriate for every situation and results depend on individual clinical factors.

Products and remedies that claim to regrow gum tissue naturally should be treated with considerable scepticism. There is no reliable evidence to support the use of oils, rinses, or other home preparations as a means of reversing established gum recession.

The most meaningful thing a patient can do is seek a professional assessment to understand why recession has occurred and what steps — if any — are appropriate for their specific situation.

---

How Can You Help Prevent Further Gum Recession?

While established gum recession cannot generally be reversed through home care alone, there are steps that may help reduce the risk of further progression — particularly once any underlying cause has been identified and addressed.

Toothbrushing

• Use a soft-bristled toothbrush rather than a medium or hard one
• Apply gentle pressure — firm brushing does not improve plaque removal and may cause gum margin trauma over time
• Use a small, circular or rolling technique rather than vigorous horizontal scrubbing
• Consider a powered toothbrush with a pressure sensor, which can help individuals who unconsciously apply excessive force
• Brush for two minutes, twice daily, but avoid brushing immediately after consuming acidic foods or drinks

Interdental Cleaning

• Clean between teeth daily using interdental brushes, floss, or another suitable interdental cleaning aid
• This helps remove plaque from areas that a toothbrush cannot effectively reach

Toothpaste

• Use a fluoride toothpaste suitable for adult use — fluoride helps protect tooth surfaces, including root surfaces that may be exposed
• Do not rinse with water immediately after brushing, as this reduces the protective effect of fluoride

Avoiding Harmful Habits

• If you smoke, seeking support to stop smoking may have a meaningful positive effect on gum health as well as general health
• Be mindful of any habits that involve contact between objects and the gum margin

Regular Dental Assessment

• Attending regular check-ups allows any changes in gum level to be detected early, contributing causes to be identified, and appropriate management to be initiated where needed

When Should You See a Dental Professional?

There is no need to panic if you notice your gums appear to have changed, but it is sensible to arrange a dental assessment if:

• You have noticed that one or more teeth appear longer than before
• Your gum line has visibly shifted
• You have developed new or increasing tooth sensitivity, particularly to cold
• You can see what appears to be an exposed tooth root
• Your gums bleed regularly when brushing or using interdental aids
• Your gums appear swollen, red, or persistently inflamed
• You have noticed changes around a single tooth that concern you
• Any of the above is getting worse rather than staying stable
• You are unsure whether what you have noticed is normal variation or a change requiring attention

A dental professional can assess the gum levels, identify any contributing factors, advise on appropriate oral hygiene, and recommend next steps — whether that involves treatment, monitoring, or onward referral.

Frequently Asked Questions

Can receding gums grow back naturally?

Gum tissue that has receded does not regenerate on its own. No home remedy or over-the-counter product has reliable clinical evidence to support claims of reversing established gum recession. What is possible is preventing further recession by addressing the underlying cause, and in selected clinical cases, a specialist procedure such as gum grafting may be considered to improve coverage over an exposed root surface. A dental assessment is the appropriate starting point.

Can brushing teeth cause gum recession?

Yes, in some cases. Brushing with excessive pressure, using a hard-bristled toothbrush, or using a vigorous horizontal scrubbing technique can, over time, cause trauma to the gum margin and contribute to recession — particularly on the outer surfaces of teeth. This does not mean that brushing causes harm when carried out correctly. Gentle, consistent brushing with an appropriate technique is beneficial for gum health, not harmful to it.

Is gum recession painful?

Gum recession itself is not always painful, and many people are unaware of it until it is noticed during a dental check-up or becomes more obvious visually. However, as the gum recedes and root surfaces become exposed, tooth sensitivity can develop — making affected teeth more responsive to temperature, sweet foods, or touch. In cases where gum disease is contributing, there may be associated gum discomfort or bleeding.

Does gum disease always cause receding gums?

Gum disease is one of the more commonly associated factors, but not everyone with gum recession has gum disease, and not everyone with gum disease will experience noticeable recession. The relationship varies depending on the type and severity of gum disease, the individual's gum tissue, and other clinical factors. Other causes — including brushing technique, tooth position, and gum tissue characteristics — can lead to recession independently of gum disease.

Why is only one tooth affected?

Recession affecting a single tooth often points to a localised cause. This might include the position of that tooth relative to the jaw bone, a localised area of particularly thin gum tissue, a specific brushing pattern, a habit or trauma affecting that area, or the way that tooth bites against opposing teeth. A dental professional can assess the affected area and help identify the most likely explanation.

Can gum recession get worse over time?

It can, particularly where an underlying contributing cause remains unaddressed. For example, untreated gum disease or persistently traumatic brushing may allow recession to continue progressing. Where recession is stable and the contributing cause has been identified and managed, further change is often less likely — though regular monitoring is still advisable. There is no guarantee of outcome in either direction, as individual circumstances vary considerably.

Is sensitive toothpaste enough to treat gum recession?

Desensitising or sensitive toothpastes can help reduce the discomfort associated with exposed root surfaces, and they are a reasonable first step for managing sensitivity. However, they do not treat the recession itself, and they do not address any underlying cause. They should be considered a supportive measure alongside — not instead of — professional assessment and appropriate management.

When does gum recession actually require treatment?

This depends on several factors, including whether recession is progressing, whether there are significant symptoms, whether the underlying cause is being adequately managed, whether root surfaces are at risk, and whether there are cosmetic concerns causing distress. Not all recession requires active intervention — stable recession in a person with good oral hygiene and no active gum disease may only need monitoring. A dental professional is best placed to advise based on the individual's clinical picture.

Can a gum graft fix receding gums?

In selected cases, gum grafting can be used to improve coverage over an exposed root surface. The procedure involves placing gum tissue — taken from another part of the mouth or from a donor source — over the area of recession. It is not suitable or necessary for everyone with receding gums, and outcomes vary depending on individual clinical factors. A specialist periodontal assessment would be needed to determine whether it is an appropriate option in a given case.

How is gum recession measured at a dental appointment?

Dentists and dental hygienists use a fine instrument called a periodontal probe to gently measure the depth of the space between the tooth and the gum, and to record where the gum margin sits relative to a reference point on the tooth. These measurements help establish the extent of any recession, track changes over time, and assess overall gum health. This type of assessment is straightforward and forms part of a thorough periodontal review.

A Note on Seeking Dental Assessment

If you have noticed changes to your gum line, increased tooth sensitivity, or anything about your gums that concerns you, arranging a dental check-up is a sensible step. A thorough assessment can help identify what is happening, clarify whether any action is needed, and provide guidance tailored to your specific situation.

Early assessment tends to allow for a wider range of management options and may help prevent further change. There is no need to wait until symptoms become more significant before seeking advice.
