Gum recession often begins unnoticed and only becomes apparent when the teeth appear longer and become sensitive to cold. This article explains why gums recede, what causes it, what you can do yourself, and when dental treatment is necessary.
What is gum recession, and why do gums recede?
Receding gums means that the gums are pulling back—from the crown of the tooth toward the root—exposing the neck of the tooth. In technical terms, this process is called gingival recession. It affects not only the visible tissue in the mouth but also the entire periodontium, including the fibers that anchor the tooth in the jawbone.
Receding gums are rarely a sudden occurrence. In most cases, the tissue recedes slowly over the course of years, which is precisely why many people don’t notice it until it’s too late. A glance in the mirror is not enough to detect gum recession early on—the definitive diagnosis is made by the dentist, who can measure the depth of the gum pockets and assess bone loss.
Healthy Gums in Comparison: How Can You Tell If Your Gums Are Receding?
Healthy gums are pale pink, fit snugly against the teeth, and do not bleed when brushed. They surround each tooth like a collar and protect the sensitive root surface from bacteria and temperature changes. If this appearance changes, it’s an early warning sign: Redness—known in medicine as erythema—and swelling of the tissue—technically called edema—indicate inflammation caused by bacteria.
When the gums recede, the border between the gums and the teeth visibly shifts downward. This makes the teeth appear longer, even though they haven’t actually grown. The earlier this change is noticed, the easier it is to influence its further progression.
Typical Symptoms: How to Recognize Receding Gums
The typical symptoms develop gradually. Look out for these signs:
- The teeth appear longer because the tooth necks are exposed
- Sensitive tooth necks react to cold, heat, sweet, or sour foods
- Bleeding gums when brushing or flossing
- Redness and swelling as visible signs of inflammation
- Deepened gum pockets between the teeth and gums
- Persistent bad breath, indicating bacterial plaque beneath the gum line
- A noticeable pressure or pulling sensation in the affected area
Anyone who notices these signs should make an appointment at the dentist’s office as soon as possible. If gum recession goes untreated, the teeth will become loose. Our article on loose teeth explains what a loose tooth means and how it can be made firm again.
What Causes Gum Recession? Causes of Gum Recession
There is no single answer to the question of what causes gum recession. In most cases, several risk factors interact and reinforce each other.
Dental plaque and poor oral hygiene
Poor oral hygiene is the most common cause. When food particles remain on the teeth, plaque—a soft, bacterial film—forms on the tooth surface. If this film is not removed regularly, it mineralizes into hard tartar. Tartar and plaque continuously irritate the gums and contribute to both inflammation and tooth decay. Regular professional dental cleanings remove deposits in areas that a toothbrush cannot reach, especially between the teeth and just below the gum line.
Periodontitis as the Most Common Cause of Tissue Loss
Periodontitis is a chronic inflammation of the periodontal tissues and develops when untreated gum inflammation—gingivitis—progresses further. Bacteria attack not only the tissues in the mouth but also the jawbone. The periodontal tissues are gradually broken down, and in advanced stages, tooth loss is a risk. Since the disease is painless for a long time, it is important to detect periodontitis early. For more information on symptoms and treatment options, see the article on periodontitis.
Incorrect Brushing Technique and Mechanical Irritation
Incorrect brushing technique can also damage the tissue. Brushing too hard or using a toothbrush with hard bristles causes mechanical wear on the gums. Soft bristles and gentle, circular motions irritate the sensitive gum line significantly less than vigorous back-and-forth scrubbing. Electric toothbrushes with pressure control help limit the amount of pressure applied.
Tobacco use, stress, and genetic predisposition
Tobacco smoking is one of the strongest risk factors: The nicotine it contains constricts blood vessels, impairs blood flow to the oral cavity, and masks inflammation because the typical bleeding of the gums occurs less frequently. Stress also weakens the immune system. In addition, genetic predisposition plays a role: Some people naturally have thin gums, causing the tissue to recede more quickly.
Hormones, Diabetes, and Other Conditions
Hormonal changes, such as those during pregnancy, make the gums softer and more susceptible to inflammation. General medical conditions also have an impact: poorly controlled diabetes mellitus promotes inflammation in the mouth and accelerates tissue breakdown, and a weakened immune system—such as in the case of an HIV infection—further increases the risk. A vitamin C deficiency also weakens connective tissue.
Bruxism, Piercings, Dentures, and Implants
Teeth grinding, medically known as bruxism, exerts constant pressure on the teeth and supporting structures and accelerates their deterioration. Lip or tongue piercings constantly rub against the tissue and cause mechanical damage exactly where the jewelry is located. Poorly fitting dentures, implants, and braces exert pressure on the surrounding tissue. Properly fitted dental prostheses are therefore important; the article on dental prostheses provides an overview. Dentures must also be checked regularly and adjusted as needed.
Inflammatory processes in the mouth demonstrate how closely gum health and overall oral health are linked. For more details, see the articles on dental fistulas and gum abscesses.
Causes of Gum Recession in Young People
Receding gums are often considered a sign of aging. This is only partly true: While the incidence does increase with age because stressors accumulate over decades, oral epidemiological data show that young adults are also affected. In their case, other factors are the primary causes: brushing too hard, piercings, orthodontic appliances, and untreated gingivitis. Anyone who notices their gums receding at a young age should take this seriously, because it’s much easier to influence the progression of the condition in its early stages.
Exposed tooth necks: the visible consequence
The recession of the gums is most clearly visible at the tooth necks. The tooth neck is the transition between the crown and the root; it is not covered by hard enamel but only by a thin layer of cementum. If it is exposed, open dentin tubules carry the stimulus directly to the nerve—which is why sensitive tooth necks react to cold, sweet, or sour foods. Exposed tooth necks are therefore not just an aesthetic concern, but the point where symptoms first become noticeable.
What are the potential consequences of receding gums?
Untreated gum recession is not limited to aesthetic concerns. The consequences of gum recession affect overall dental health:
- Sensitive tooth necks: The exposed root surface lacks enamel and therefore reacts painfully to stimuli.
- Root caries: The softer root dentin is more susceptible to tooth decay than the tooth crown.
- Deeper gum pockets: These provide a haven for bacteria and can no longer be cleaned with a toothbrush.
- Bone loss: If the inflammation progresses, the jawbone loses substance and the tooth loses its support.
- Aesthetic impairment: Many people find the visible black triangles between their teeth unsightly.
What to Do About Receding Gums? The First Steps
Anyone who notices that their gums are receding should first consult a dentist to determine how far the recession has progressed. Only then can a decision be made about which measures are appropriate. Depending on the findings, the following steps are typically taken at the dentist’s office:
- professional teeth cleaning to remove plaque and tartar
- Treatment of existing periodontitis or gingivitis
- Adjustment of toothbrush and brushing technique
- Quitting smoking to relieve pressure on the gum tissue
- a bite guard if bruxism is the cause
Even in advanced cases of gum recession, the progression of the condition can often be significantly slowed.
Home Remedies for Receding Gums: What Really Works?
When You Should Schedule an Appointment with Your Dentist
Home remedies are a supplement, not a treatment. You should make an appointment at the latest when your gums bleed regularly while brushing, when tooth necks are exposed, or when a tooth becomes loose. Even if you have no symptoms, an annual checkup is recommended.
Numerous tried-and-true home remedies for receding gums are circulating online—from chamomile tea and sage rinses to oil pulling. Realistically speaking, such home remedies can soothe irritated gum tissue and support healing after a dental procedure. However, they do not remove plaque beneath the gum line or tartar that has already formed, and they cannot regenerate lost tissue.
It’s also important to know what you shouldn’t try: Do not use baking soda or salt paste for brushing—both act like sandpaper on the root surfaces and gums. Antibacterial mouthwashes are useful as a temporary supplement, but they do not replace mechanical cleaning.
Treatment of Gum Recession at the Dentist’s Office
Treatment depends on the cause and how far the recession has progressed.
Professional teeth cleaning and periodontitis treatment
In early cases, professional teeth cleaning combined with an appropriate brushing technique is often sufficient. If periodontitis is present, the inflammation is treated first: plaque and bacteria are mechanically removed from beneath the gums so that the tissue can heal and reattach to the tooth. The goal of this treatment is to stabilize the periodontal tissues and halt the progression of gum recession.
Surgical Procedures for Severe Recession
In cases of significant tissue loss, conservative measures are no longer sufficient. In such cases, surgical procedures may be considered, most notably a connective tissue graft: The specialist removes tissue from another area of the oral cavity—usually the palate—and transplants it to the affected site. Exposed tooth necks are covered again, protecting the tooth root. This improves the aesthetic outcome while also reducing sensitivity.
If a tooth has already been lost, solutions such as a post-retained tooth or—if multiple teeth are affected—an approach like All-on-4 may be considered.
Stopping Gum Recession: Can It Be Stopped?
It is possible to stop gum recession as long as the cause is identified and consistently treated. If periodontitis is treated and home care habits are adjusted, the recession often comes to a halt. The key is to eliminate the triggering factor—whether that’s incorrect brushing pressure, plaque, or smoking.
However, lost tissue does not regrow on its own. New gum tissue does not form spontaneously and cannot regenerate on its own; surgical intervention is required to stop the recession and cover the tooth necks again.
Preventing Gum Recession: Preventive Care for Dental Health
Prevention is easier than treatment. To avoid gum recession, this preventive measure has proven effective:
- Brush twice a day for two minutes, using a soft-bristled toothbrush and applying no pressure
- Daily cleaning of the spaces between teeth with dental floss or interdental brushes
- Professional teeth cleaning once or twice a year
- A balanced diet with sufficient vitamin C
- Avoid smoking
- If you grind your teeth at night, have a mouthguard made as soon as possible
- Attend follow-up appointments and schedule an appointment early if you experience any symptoms
Regular checkups at the dentist are the most effective way to ensure long-term dental health. Proper care remains important even in old age, as the guide to dental care for seniors shows.
How much does a gum graft cost?
The cost depends on the extent of the treatment, the number of affected teeth, and the procedure chosen. A professional dental cleaning is significantly less expensive than a connective tissue graft, which is billed as a surgical procedure requiring follow-up care. Statutory health insurance plans cover a portion of periodontitis treatment if medically indicated; however, they do not cover procedures performed for purely cosmetic reasons. The dental practice will provide reliable figures in the treatment and cost plan following the examination.
Which toothpaste helps when the gums are receding?
If your tooth necks are exposed, a toothpaste for sensitive teeth is recommended. Such products contain active ingredients like potassium nitrate, stannous fluoride, or arginine, which seal the tiny tubules in the root dentin and reduce the pain response to cold or sweet foods. Look for a low abrasion rating (RDA)—highly abrasive whitening toothpastes are unsuitable for exposed tooth necks. However, a good toothpaste is no substitute for professional teeth cleaning or treatment of the underlying cause.
Conclusion
Gum recession often begins unnoticed and is usually only detected once the tooth necks are exposed and become sensitive. Poor oral hygiene, periodontitis, incorrect brushing technique, and tobacco use are among the most common causes. The earlier the recession is detected, the easier it is to halt—regular preventive care and a timely visit to the dentist are the most effective measures.
Frequently Asked Questions About Gum Recession
How do you know if you have receding gums?
Typical symptoms include teeth that appear longer, sensitive tooth necks, bleeding gums when brushing, and redness and swelling of the gum tissue. Bad breath and deepened gum pockets also indicate the onset of gum recession.
What can be done about receding gums?
The first step is to schedule an appointment at the dentist’s office to determine the cause. Depending on the findings, treatment may include a professional teeth cleaning, treatment of inflammation, and adjustments to your toothbrush and brushing technique.
Can gum recession be stopped?
Yes. If the underlying cause is consistently treated, gum recession can be halted in many cases. However, gum tissue that has already been lost will not regrow on its own.
Can gum tissue regrow?
Receding gums do not regenerate on their own. Only a surgical procedure, such as a connective tissue graft, can replace lost tissue.
Do home remedies help with gum recession?
Chamomile, sage, or oil pulling can soothe irritated gum tissue, but they do not remove bacterial plaque or rebuild tissue. Home remedies are not sufficient as a standalone treatment.
How much does gum regeneration cost?
The cost depends on the extent of the procedure and the technique used. A professional teeth cleaning is significantly less expensive than a surgical graft; the exact amount is specified in the treatment and cost plan.
What contributes to receding gums?
Plaque and dental tartar, periodontitis, improper brushing technique, tobacco use, bruxism, piercings, and ill-fitting dentures. Genetic predisposition, hormonal changes during pregnancy, and poorly controlled diabetes mellitus are also risk factors.
When does gum recession become dangerous?
The condition becomes critical when the gum pockets deepen and the jawbone begins to resorb. This can lead to root caries, loose teeth, and, if left untreated, tooth loss.

Abscess
An abscess is the accumulation of pus in a body cavity that is not naturally present. In this case, the pus formed during an inflammatory process penetrates into the surrounding body tissue, where it thus creates its cavity. In the cavity formed by the inflammatory melting of the tissue, the pus accumulates against the adjacent tissue.
