You may notice that one tooth looks longer than the teeth beside it. Or perhaps a familiar spot near the gumline suddenly feels sensitive when you drink something cold. Sometimes the change is so gradual that you first recognize it in an old photograph.
These can be signs of receding gums, also called gingival recession. The gumline has shifted away from its original position, exposing part of the tooth that was previously covered by tissue.
Recession is the change you can see. Understanding why it happened determines what should happen next.
A receding gumline does not automatically mean you have gum disease. And it does not automatically mean you need a gum graft. Some areas are stable and can be monitored. Others need treatment because of inflammation, sensitivity, tooth-root damage, or continuing tissue loss.
The important distinction is between protecting the exposed tooth, treating any underlying disease, and deciding whether the gum tissue itself needs to be restored. Those are related decisions, but they are not the same treatment.
What does it mean when your gums are receding?
Healthy gum tissue forms a close-fitting border around each tooth. The part of the tooth normally visible above the gumline is the crown. Below that border is the root, which has a different surface from the enamel covering the crown.
With gum recession, the edge of the gum moves toward the root. More of the tooth becomes visible, and part of the root surface may be exposed. Because the root is not protected by enamel in the same way as the crown, it can be more vulnerable to sensitivity, wear, and decay.
A tooth can look longer without having moved. Sometimes it is the gumline that has changed.
Recession can occur on the front of one tooth, around several teeth, or alongside changes in the gums between neighboring teeth. Those spaces between teeth are sometimes described as black triangles, but a black triangle and a receding outer gumline are not necessarily the same condition.
How can you tell if your gums are receding?
Receding gums often develop without pain. The first signs may be changes in appearance rather than discomfort.
- A tooth looks longer. The gumline sits farther from the biting edge than it used to.
- The gumline looks uneven. One tooth has noticeably less gum coverage than the neighboring teeth.
- Cold or brushing causes sensitivity. An exposed root may react when it comes into contact with temperature changes or touch.
- A darker or yellower area appears near the gumline. Exposed root surfaces may look different from the enamel above them.
- A notch develops near the gumline. A worn area where the crown meets the root can occur alongside recession.
- The gums bleed or appear inflamed. Bleeding points to a need to assess gum health, even though recession itself does not always cause bleeding.
These signs do not establish the cause by themselves. The same visible recession can occur in someone with healthy supporting bone or in someone with periodontal disease. Examination and measurements help distinguish between the two.
What causes receding gums?
Gum recession rarely comes down to one simple explanation. The thickness of the tissue, position of the tooth, inflammation, daily habits, and local anatomy can all influence what happens to the gumline.
Gum disease and loss of supporting tissue
Plaque buildup can cause inflammation around the teeth. If periodontitis develops, the tissues and bone supporting the teeth can be damaged. As support is lost, the gums may recede. Bleeding, deeper gum pockets, loose teeth, or shifting teeth can be additional warning signs.
Brushing pressure and technique
Repeatedly scrubbing the gumline with force, particularly with a stiff brush, can injure the surrounding tissues and wear tooth surfaces. Brushing trauma may contribute to recession, although it is often difficult to separate its effect from other factors in an individual patient.
Thin gum tissue and natural anatomy
Some people naturally have thinner gum tissue or a thinner layer of supporting bone around particular teeth. Tooth-root prominence and the attachment of the lip or cheek tissues can also influence how vulnerable an area is to recession.
Tooth position and orthodontic changes
A tooth positioned toward the outside of the supporting bone may have less tissue covering its root. When planning braces or clear aligners, the starting position of the teeth, gum thickness, and planned movement all deserve attention. Orthodontic treatment does not automatically cause gum recession.
Tobacco use and ongoing inflammation
Smoking is associated with periodontal problems and less predictable healing. Persistent plaque, tartar, and inflammation can add to the conditions that make the tissues around the teeth less healthy.
Local irritation and previous dental conditions
A restoration that is difficult to clean, a high or tight tissue attachment, a lip piercing, or damage near the neck of a tooth can sometimes contribute to a local problem. Recession may also become more visible after periodontal inflammation has been treated and swollen tissues return to a healthier shape.
More than one factor may be present at the same tooth. The useful question is which factors are active, which can be changed, and whether the recession is stable.
Can receding gums grow back naturally?
Once gum tissue has receded and exposed the root, it generally does not return to its former position simply because you change toothpaste, use a mouthwash, or begin flossing more consistently.
That does not mean the situation cannot improve. Inflamed gums can become healthier with appropriate care. Sensitivity can be managed. Ongoing tissue loss can sometimes be prevented, and selected recession defects can be treated with periodontal root-coverage procedures.
Healthier gums and a higher gumline are not the same outcome. Good home care protects the tissue; it does not reliably recreate tissue that has been lost.
Products promising to regrow receding gums should be viewed with caution. A treatment plan needs to address the actual cause, not just the appearance of the exposed root.
How are receding gums treated?
Treatment depends on whether the gumline is stable, whether there is active periodontal disease, how much root is exposed, and whether the area is sensitive or difficult to maintain. Not every tooth with recession needs surgery.
Examination and monitoring
The gumline and periodontal pockets can be measured and recorded over time. When recession is shallow, stable, and not causing problems, observation and prevention may be appropriate.
Control plaque and treat gum disease
A professional cleaning and improved daily plaque removal may be sufficient for gingivitis. When periodontitis is present, treatment can require deeper periodontal cleaning, ongoing maintenance, and sometimes specialist care. The priority is to control the disease, not to cover the root before the tissues are healthy.
Change the habits affecting the gumline
A softer brush, lighter pressure, and a personalized cleaning technique can reduce unnecessary irritation while still removing plaque. Local causes such as a poorly contoured restoration may also need attention.
Protect sensitive or worn root surfaces
Desensitizing toothpaste or professionally applied fluoride products can help manage some exposed-root sensitivity. If a groove, root cavity, or structural defect is present, a carefully planned restoration may protect that area. Dental bonding changes the tooth surface; it does not replace missing gum tissue.
Consider a gum graft or root-coverage procedure
For selected cases, a periodontist can use a graft or another soft-tissue procedure to cover part or all of an exposed root, increase tissue thickness, or help protect a vulnerable area. The expected amount of coverage depends on the defect and surrounding support.
Coordinate with orthodontic or restorative planning
When tooth position, a cervical defect, or a planned restoration affects the gumline, treatment may require more than one discipline. The right sequence matters: periodontal health and tooth position should be understood before cosmetic changes are made.
A comprehensive dental examination can identify whether the issue belongs primarily to preventive and periodontal care, a restorative decision, or an evaluation by a periodontal specialist.
What can you do at home to keep your gums from receding further?
Daily care matters, but the goal is gentle, thorough plaque removal rather than scrubbing harder. Changes at home should support professional diagnosis, not substitute for it.
- Brush twice a day with a soft-bristled brush. Use light pressure, paying attention to the border where teeth and gums meet.
- Clean between your teeth every day. Floss or use an appropriately sized interdental cleaner without snapping or forcing it into the gums.
- Check your technique. If bristles splay quickly or you scrub forcefully, ask your dental team to demonstrate a gentler approach.
- Do not ignore bleeding. Gums that bleed repeatedly need evaluation even when there is no pain.
- Protect exposed roots. Ask whether a sensitivity toothpaste or fluoride treatment is appropriate for your situation.
- Keep periodontal appointments. Regular examinations and cleanings help track whether a gumline has changed.
- Avoid tobacco. Smoking is a major risk factor for periodontal disease and complicates healing.
Dr. Marta emphasizes daily brushing, cleaning between every tooth, and preventive visits because keeping natural teeth healthy depends on what happens between appointments as much as what happens during them.
When should you have receding gums checked?
A gumline that has looked the same for years is different from one that is visibly changing. An evaluation is particularly useful when any of the following are present:
- The recession is new or getting worse. Changes should be measured rather than estimated from memory.
- One tooth looks much longer than the others. A localized problem may involve tooth position, tissue thickness, or irritation.
- The root is becoming sensitive or worn. Exposed-root surfaces can need protection.
- The gums bleed, swell, or remain tender. These symptoms call for a periodontal assessment.
- You have noticed loose or shifting teeth. Supporting bone and periodontal health need to be evaluated promptly.
- You are considering braces, aligners, bonding, or veneers. The condition of the gumline belongs in the treatment plan before changing the teeth.
Significant swelling, pus, fever, or a rapidly worsening problem warrants prompt dental attention rather than waiting for a routine cleaning.
The goal is to preserve the gum and the tooth beneath it.
Two people can have almost identical-looking recession and need completely different care. One may have thin, otherwise healthy tissue around a tooth that sits forward in the arch. Another may have lost periodontal support because of disease. A third may have an exposed root that has become sensitive or worn.
Treating all three situations the same way would miss what matters most. The starting point is to understand the health of the supporting tissues, the position of the tooth, and whether the gumline is continuing to change. From there, treatment can be as conservative or as comprehensive as the condition requires.
Key takeaways
Receding gums are a visible change, but the cause determines the treatment.
- 01Gum recession exposes more of a tooth or its root and can make a tooth appear longer.
- 02Periodontal disease is one cause, but tissue thickness, tooth position, brushing habits, and local anatomy can also contribute.
- 03Receded gum tissue generally does not grow back on its own, even when oral hygiene improves.
- 04Treatment can involve monitoring, periodontal care, gentle plaque control, sensitivity management, or specialized root-coverage procedures.
- 05Bonding can protect a damaged or sensitive root surface in selected cases, but it does not rebuild missing gum tissue.
- 06New or progressing recession, bleeding gums, or tooth looseness deserve an examination.
Frequently asked questions
Receding gums questions answered.
Can receding gums grow back on their own?
Established gum recession generally does not reverse simply with home care. Removing inflammation and improving plaque control can help stabilize the area, while selected defects may be treated with soft-tissue root coverage. A review of gingival recession treatment explains why treatment first addresses contributing factors, then considers whether surgical root coverage is appropriate.
Why are my gums receding even though I brush and floss?
Good home care is important, but it is not the only factor affecting the gumline. Tissue thickness, tooth position, inflammation, smoking, and other anatomical or local factors also matter. A 2025 systematic review and meta-analysis of gum recession risk factors found associations with several different conditions, including periodontal disease and dental plaque. A dentist needs to assess which factors apply to an individual tooth.
Can brushing too hard cause gum recession?
Aggressive brushing can injure tissues and wear the tooth near the gumline, so using a gentle technique is sensible. However, recession usually has more than one potential contributor. A systematic review of traumatic toothbrushing reported that evidence linking brushing trauma directly to the development of recession remains inconclusive. Brushing force should be considered as part of a broader assessment, not assumed to be the only cause.
Does gum recession always mean periodontal disease?
No. Periodontitis can cause recession through loss of supporting tissue, but recession may also occur around teeth without periodontal disease. A literature review of the causes of gingival recession discusses multiple contributing factors, including tissue anatomy, tooth position, brushing habits, and inflammation. Periodontal measurements and, when indicated, radiographs help distinguish these situations.
Can braces or clear aligners cause receding gums?
Tooth movement and gum health interact, but not everyone who has orthodontic treatment develops recession. A systematic review of recession risk factors after orthodontic treatment found that tooth movement, tissue characteristics, oral hygiene, and starting dental anatomy all deserve consideration. This is why gum thickness and periodontal health should be assessed during orthodontic planning.
Can dental bonding fix receding gums?
Bonding can restore or protect a worn or damaged tooth surface near an exposed root in selected situations, but it does not grow or replace the missing gum. An evidence-based recommendation on recession with cervical tooth defects describes cases in which restorative care and periodontal root coverage may need to be planned together.
When is a gum graft recommended?
A gum graft or another periodontal root-coverage procedure may be considered for progressing recession, exposed-root sensitivity, inadequate tissue thickness, or an appearance concern when the anatomy supports treatment. A systematic review of long-term root coverage found that combining a coronally advanced flap with a connective tissue graft provided more stable long-term root coverage in the studied defects than flap advancement alone. Whether an individual tooth is suitable requires a periodontal evaluation.
Do receding gums always need treatment?
Not necessarily. A small, stable area with healthy tissues and no sensitivity may be monitored. If the recession is progressing, the root is becoming damaged, or periodontal disease is present, active care becomes more important. The clinical review on when and how to treat recession emphasizes evaluating risk factors and symptoms before choosing between preventive, restorative, and surgical options.
