Gingival Recession: How to Manage Receding Gums and Protect Your Smile
Gingival Recession: How to Manage Receding Gums and Protect Your Smile
Gingival recession, commonly known as receding gums, occurs when the gum margin moves away from its normal position and exposes part of the tooth root.
Patients often first notice that:
- one or more teeth appear longer;
- the gum line looks uneven;
- the tooth root has become visible;
- sensitivity has developed around the gum line.
Gum recession is not only an aesthetic concern. Exposed root surfaces are more vulnerable to sensitivity, root caries, and non-carious tooth wear, which is why identifying the cause and preventing further progression are important.
Regular dental examinations, early diagnosis, appropriate oral hygiene, and individual periodontal care are essential for maintaining healthy gums.
At the end of this article, you can also watch our video with Dr Vasilena Marinova from BalCare Dental Clinic, who discusses gingival recession and the available approaches for protecting and restoring exposed root surfaces.
What Is Gingival Recession?
Gingival recession is the displacement of the gum margin towards the root of the tooth, resulting in exposure of the root surface.
Unlike the visible crown of the tooth, which is covered by highly mineralised enamel, the root is covered by cementum, with dentine underneath.
These tissues are softer and more vulnerable than enamel.
As a result, an exposed root may be more susceptible to:
- sensitivity;
- mechanical wear;
- erosion;
- root caries.
Gingival recession can affect a single tooth, several teeth, or larger areas of the mouth.
It is more common in people with a thin periodontal phenotype, where the gum tissue and supporting bone are naturally thinner.
What Causes Receding Gums?
Gingival recession is usually multifactorial, meaning that several factors may contribute to its development.
Aggressive Toothbrushing
Brushing with excessive pressure, particularly over a long period, may contribute to trauma at the gum margin.
Risk may increase when patients use:
- hard toothbrush bristles;
- excessive brushing force;
- repetitive horizontal scrubbing movements;
- highly abrasive toothpaste.
The aim should not be to brush less thoroughly, but to use an effective and gentle technique.
Thin Periodontal Phenotype
Some people naturally have thinner gum tissue and a thinner layer of bone around the teeth.
This is known as a thin periodontal phenotype.
These patients may be more susceptible to recession when other contributing factors are present, such as:
- traumatic brushing;
- tooth position outside the ideal bony envelope;
- inflammation;
- orthodontic tooth movement;
- local trauma.
A thin phenotype does not mean that recession will necessarily develop, but it can influence individual risk.
Periodontal Disease
Periodontitis can lead to loss of the tissues and bone supporting the teeth.
As periodontal support is lost, the gum margin may also recede.
In these cases, recession may be accompanied by:
- bleeding gums;
- periodontal pockets;
- bone loss;
- tooth mobility;
- changes in tooth position.
This type of recession requires treatment of the underlying periodontal disease.
Tooth Position and Orthodontic Factors
The position of a tooth within the jawbone can influence the thickness of the gum and bone surrounding it.
Teeth positioned towards the outer boundary of the alveolar bone may have thinner supporting tissues.
Orthodontic treatment itself does not automatically cause recession. However, in susceptible patients, certain tooth movements outside the available bony envelope may increase the risk.
For this reason, periodontal phenotype and bone support should be considered during orthodontic planning, particularly in patients who already have thin gums or existing recession.
Local Trauma
Repeated mechanical irritation may also contribute to recession.
Possible causes include:
- oral piercings;
- poorly fitting dental appliances;
- traumatic habits;
- accidental injury;
- local irritation around restorations.
Identifying and removing the traumatic factor is an important part of treatment.
High or Strong Frenum Attachment
In selected patients, the position or pull of the frenum may contribute to tension around the gum margin.
The clinical significance varies and should be assessed individually.
What Are the Consequences of Gingival Recession?
Gum recession can have both functional and aesthetic consequences.
Exposed Root Surfaces
When the root becomes exposed, it loses the protection normally provided by the surrounding gum tissue.
Because root surfaces are softer than enamel, they can be more vulnerable to:
- abrasion;
- erosion;
- caries;
- surface defects.
Tooth Sensitivity
Dentine hypersensitivity is one of the most common symptoms associated with gingival recession.
Patients may experience a short, sharp sensation when the tooth is exposed to:
- cold drinks;
- hot foods;
- sweet foods;
- acidic foods;
- cold air;
- toothbrushing.
The degree of sensitivity varies considerably between patients.
Non-Carious Cervical Lesions
Loss of tooth structure may sometimes develop around the neck of the tooth.
These defects are often described as non-carious cervical lesions.
They are usually multifactorial and may involve a combination of:
- mechanical abrasion;
- chemical erosion;
- tooth-loading factors;
- individual anatomy.
They should therefore not automatically be attributed to toothbrushing alone.
Increased Risk of Root Caries
Exposed root surfaces are more susceptible to decay than enamel-covered crowns.
The risk is higher when there is:
- plaque accumulation;
- frequent sugar intake;
- dry mouth;
- inadequate fluoride exposure;
- difficulty cleaning the affected area.
Aesthetic Changes
Recession can make one tooth appear longer than neighbouring teeth and may create an uneven gum line.
This can be particularly noticeable in the front of the mouth.
Some patients also develop visible spaces or “black triangles” between teeth when the gum tissue between them is reduced.
Can Receding Gums Grow Back Naturally?
Once the gum margin has receded, it does not usually return to its original position simply through improved brushing or mouthwash.
However, appropriate treatment can:
- stop or slow further progression;
- reduce sensitivity;
- protect the exposed root;
- improve oral hygiene;
- improve aesthetics.
In selected cases, periodontal plastic surgery and soft-tissue grafting can provide partial or complete root coverage.
How Is Gingival Recession Diagnosed?
A dental or periodontal examination may include:
- measuring the amount of recession;
- assessing gum thickness;
- checking periodontal pocket depths;
- evaluating plaque and inflammation;
- examining the exposed root surface;
- assessing tooth position;
- checking the surrounding bone when necessary;
- evaluating brushing habits and other local factors.
The first step is determining why the recession developed.
Treatment that addresses only the appearance without controlling the underlying cause may not provide a stable long-term result.
Treatment of Gingival Recession
The appropriate treatment depends on:
- the depth and width of the recession;
- the amount of gum tissue present;
- the condition of the supporting bone;
- tooth position;
- sensitivity;
- aesthetic concerns;
- the underlying cause.
1. Correcting Oral-Hygiene Technique
If traumatic brushing contributes to the problem, the technique should be modified.
Patients may be advised to:
- use a soft toothbrush;
- avoid excessive pressure;
- use gentle controlled movements;
- avoid aggressive horizontal scrubbing;
- choose an appropriate toothpaste.
An electric toothbrush with a pressure sensor may also help some patients reduce excessive brushing force.
2. Managing Tooth Sensitivity
For exposed root surfaces that are sensitive, treatment may include:
- desensitising toothpaste;
- fluoride-containing products;
- professional desensitising agents;
- other protective treatments when clinically appropriate.
These measures do not move the gum back into position, but they can reduce discomfort.
3. Composite Restoration
When recession is accompanied by significant loss of tooth structure, a composite restoration may sometimes be used to restore the cervical area of the tooth.
This can help:
- protect exposed dentine;
- reduce sensitivity;
- restore lost tooth structure;
- improve aesthetics.
However, composite material does not replace missing gum tissue.
Whether restorative treatment is appropriate depends on the individual defect.
4. Soft-Tissue Grafting
For deeper recession, progressive recession, thin periodontal tissues, or significant aesthetic concerns, gum grafting may be considered.
A commonly used approach involves transferring connective tissue from the palate to the affected area.
Depending on the case, surgery may help:
- cover part or all of the exposed root;
- increase tissue thickness;
- improve tissue stability;
- reduce sensitivity;
- improve the appearance of the gum line.
The predictability of complete root coverage depends on the type of recession and the condition of the surrounding tissues.
5. Other Periodontal Plastic Surgery Techniques
Modern periodontal surgery offers several approaches to root coverage.
These may include:
- coronally advanced flap procedures;
- connective tissue grafts;
- tunnel techniques;
- selected biomaterials.
The most appropriate method is determined according to the anatomy and clinical condition of the individual patient.
6. Combined Restorative and Surgical Treatment
In some cases, recession occurs together with significant loss of the tooth structure near the gum line.
A combined treatment plan may therefore be required.
This can involve:
- restoring part of the lost tooth structure;
- performing periodontal plastic surgery to improve soft-tissue coverage.
Careful planning is important so that the restoration and gum surgery complement one another.
How Can Gingival Recession Be Prevented?
Not every case can be completely prevented, particularly when anatomical or genetic factors are involved.
However, several measures can reduce the risk of progression.
Use the Correct Brushing Technique
Brush thoroughly but gently.
A soft toothbrush and controlled movements are usually preferable to forceful scrubbing.
If you are unsure about your technique, ask your dentist or dental hygienist to demonstrate the most appropriate approach.
Maintain Excellent Plaque Control
Plaque-induced inflammation can negatively affect periodontal health.
Daily care should include:
- brushing twice a day;
- interdental cleaning;
- professional cleaning when required.
Use Fluoride Toothpaste
Fluoride toothpaste is particularly useful when root surfaces are exposed because it can help reduce the risk of root caries and support remineralisation.
It does not regenerate lost gum tissue, but it helps protect the exposed tooth surface.
Be Careful with Acidic Foods and Drinks
Acidic foods and beverages do not necessarily cause gum recession directly.
However, when root surfaces are already exposed, frequent acid exposure can contribute to erosion and loss of dentine.
Examples include:
- citrus drinks;
- frequent lemon consumption;
- fizzy drinks;
- energy drinks;
- acidic juices.
After acidic foods or drinks, rinsing with water and avoiding immediate aggressive brushing may help protect softened tooth surfaces.
Attend Regular Dental Examinations
Regular examinations allow the dentist to monitor:
- existing recession;
- changes in gum level;
- periodontal health;
- root sensitivity;
- tooth wear;
- oral-hygiene technique.
Early recognition is particularly important in patients with a thin periodontal phenotype or previous periodontal disease.
When Should You See a Dentist or Periodontist?
Arrange an assessment if you notice:
- a tooth that appears longer than before;
- visible root surfaces;
- increasing sensitivity;
- an uneven gum line;
- progressive recession;
- bleeding or swollen gums;
- cervical tooth defects;
- recession developing during orthodontic treatment.
Earlier assessment makes it easier to identify the contributing factors and determine whether monitoring, conservative care, or surgical treatment is appropriate.
Conclusion
Gingival recession is more than an aesthetic change in the gum line.
Exposed root surfaces can become sensitive and more vulnerable to caries and wear, while progressive recession may indicate an underlying periodontal, anatomical, or mechanical problem.
The most effective management begins by identifying the cause.
Treatment may range from:
- improving brushing technique;
- controlling inflammation;
- managing sensitivity;
- restoring damaged tooth structure;
to soft-tissue grafting and periodontal plastic surgery in selected cases.
