Gum recession (gingival recession) is a condition in which the soft tissue of the gums gradually recedes from the tooth, exposing the root that is normally not visible under normal conditions. The result is a tooth that looks “longer” than it actually is, increased sensitivity, and increased risk of cavities on the root. Surgical tooth extraction
This is one of the most common periodontal diseases, and it is dangerous because it progresses slowly and often goes unnoticed until it causes serious problems.
In this text we explain why gum recession occurs, how to recognize it, what the consequences are if it is ignored, and which therapies today give the best results.
What is gum recession?
Tooth roots are naturally embedded in the bone of the jaw and covered by the gums (gingiva). The gums serve as a barrier that protects the root from bacteria, food, and temperature changes.
When the gingiva recedes, the root remains unprotected, because unlike the tooth crown which is covered with hard enamel, the root is covered with a much thinner layer called cementum. Cementum wears down quickly under the effects of external factors, so the dentin below it becomes directly exposed – which leads to painful sensations and further complications.
Gum recession can affect only one tooth, but very often it affects several teeth at the same time, especially if the cause is systemic (for example, improper brushing or periodontal disease).
Symptoms of gum recession – how to recognize gingival recession
Gingival recession develops gradually, so it is important to know what to watch for:
Tooth looks bigger than before. This is the most common and most noticeable sign. The crown does not change, but since the gums recede downward (or upward on upper teeth), the tooth visually appears elongated. Patients usually notice this on canines, since they are the most exposed.
Sensitivity to hot and cold. When the cementum on the root disappears, the dentin is directly exposed to temperature changes. A sip of cold water or hot tea causes a short, sharp pain. Sensitivity to sweet and sour also occurs.
Bleeding gums. One of the earliest signs of recession is bleeding right at the gum line – usually when brushing teeth, using dental floss, or eating harder foods like raw vegetables. This symptom often goes unnoticed because it only occurs under pressure, so people easily overlook it.
Visible yellowish line on the tooth. Where the enamel ends and the root begins, a change in color can be noticed – this is the exposed surface of the root.
If you notice any of these symptoms, it is a signal that you should visit a dentist. The earlier you respond, the greater the chances for full recovery.
Causes of gum recession
There are several reasons why recession occurs, and often it is a combination of factors:
Improper and overly aggressive tooth brushing is one of the most common causes. Strong horizontal “scrubbing” motions and a hard toothbrush mechanically damage the gums and over time push them away from the root.
Periodontal disease (gum disease) is an infectious cause of recession. Bacteria in dental plaque and tartar cause chronic inflammation that destroys the supporting tissue around the tooth, including the gingiva.
Grinding and clenching teeth (bruxism) creates excessive pressure on the teeth and supporting tissue, which over time leads to gum recession, especially in combination with other factors.
Irregular tooth position – teeth that are positioned outside the dental arch experience different loading and have thinner bone on one side, which promotes recession.
Smoking significantly reduces blood supply to the gums and slows healing, which increases the risk of all periodontal diseases, including recession.
Inadequate old prosthetic restorations – poorly fitted crowns, bridges, or veneers can irritate the gingiva and cause their recession. Gum recession from veneers and under a bridge is a common reason for patients to come in.
Hereditary factors – some people genetically have a thinner layer of gingiva or a highly positioned frenum attachment, which makes them more prone to recession.
Orthodontic therapy – tooth movement with a fixed appliance, if not carefully controlled, can lead to bone loss and gum recession.
Consequences of gingival recession
If recession is not treated, the consequences become increasingly serious. The first and most common complaint is tooth oversensitivity to thermal and chemical irritants – food, drink, and even breathing cold air can cause a short, sharp pain that makes daily life difficult.
In addition to sensitivity, the exposed surface of the root is much softer than enamel and susceptible to bacterial attack, so root caries is a common complication that progresses faster and is harder to treat than classic caries on the crown. Visible tooth roots, especially on front teeth and canines, also create a significant aesthetic problem that affects confidence and the appearance of the smile.
In the most severe, advanced stages, the destruction of supporting tissue and bone reaches the point where the tooth begins to move, and without timely intervention – the final outcome is complete tooth loss.
How is gum recession treated
Treatment depends on the stage of recession and the cause that led to it.
Early stage – change of habits and professional hygiene
If recession is detected in time, it is often sufficient to correct the tooth brushing technique (switch to a soft brush and proper vertical movements) and have professional cleaning of tartar done by a dentist. Proper maintenance of oral hygiene at this stage can stop further progression.
Correction of the cause
If recession is a result of bite disorder or irregular tooth position, orthodontic therapy can solve the underlying problem. In case of periodontal disease, the infection is first treated – by cleaning tartar, treating pockets, and if necessary root canal treatment.
Surgical therapy – for advanced recessions
When conservative methods are not sufficient, surgical procedures are applied:
SMAT (subepithelial connective tissue graft) is a modern procedure in which a small piece of connective tissue from the palate is transplanted to the exposed root of the tooth. The tissue is sutured to the place where the gums have receded, which covers and protects the root again. This is one of the most successful methods with a high success rate.
PRF therapy uses preparations obtained from the patient’s blood that stimulate tissue regeneration. By applying PRF preparations to the damaged area, natural healing is stimulated and the gums are brought back to their place.
Based on the size and location of the recession, a specialist in oral surgery and periodontology determines which type of therapy gives the best results in a particular case.
Natural remedy for gum recession – does it exist?
This is one of the most common questions patients ask. The truth is that once the gums recede, they cannot return to their previous place on their own – this requires dental intervention. However, there are things you can do at home to slow down or stop further progression:
Use a soft toothbrush and gentle motions when brushing. Switch to toothpaste with fluoride or hydroxyapatite that strengthens enamel and reduces sensitivity. Rinsing the mouth with mild solutions (for example, saline) can help reduce inflammation. Gel for gum recession based on hyaluronic acid, which can be found in pharmacies, helps in regeneration of soft tissue.
These steps are not a substitute for professional therapy, but can help as a supplement to dental treatment and in preventing further deterioration.
How to prevent gum recession
Prevention is always better than treatment. Here is what you can do:
Brush your teeth twice a day with a soft brush, using gentle circular or vertical motions – never rough horizontal ones. Use dental floss or interdental brushes to clean the spaces between teeth. Visit the dentist regularly, at least twice a year, for check-ups and professional cleaning. If you grind your teeth, ask for a protective splint to be made. Quit smoking – this is one of the most important steps for gum health.
Gum recession in children
Although gingival recession is usually associated with adults, it can also occur in children and adolescents. The most common causes in the younger population are aggressive tooth brushing, irregular tooth position in the arch, and a short frenum (the tissue that connects the lip and gum). In children, early detection is especially important, because timely orthodontic correction and training in proper hygiene can completely prevent further progression.
