Gum recession is when the gum margin moves away from its normal position and exposes more of the tooth or root. Common contributors include periodontal disease, aggressive brushing, thin gum tissue and tooth position. Lost gum tissue usually does not regrow on its own, but the cause can often be controlled and selected cases may benefit from gum-graft or root-coverage treatment.
Have you noticed that one tooth seems to look a little longer than it used to? Perhaps your teeth have become sensitive to cold drinks, or you can see a yellowish area near the gumline that was not visible before. These can be signs of gum recession.
Gum recession occurs when the gum tissue surrounding a tooth moves away from its normal position, exposing more of the tooth — and sometimes part of the tooth root. It may affect one tooth or several teeth, and it often develops gradually.
Although recession is common, the important question is not only how much gum has moved. It is why the change is happening and whether it is stable or progressing.
What is Gum Recession?
Why Do Gums Recede?
1. Gum disease (periodontitis)
Periodontitis can damage the gum attachment and bone that support the teeth. As supporting tissues are lost, the gumline may recede and teeth can appear longer. Other warning signs may include bleeding gums, persistent bad breath, spaces developing between teeth, deeper gum pockets or loose teeth.
2. Brushing too hard
Forceful horizontal scrubbing, especially with a firm toothbrush, can repeatedly traumatise a susceptible gum margin. Brushing harder does not necessarily clean better; effective plaque removal should be through but gentle.
3. Naturally thin or delicate gum tissue
People vary in the thickness of their gum tissue and the amount of bone covering the roots. A thin gum phenotype can make some sites more susceptible to recession, particularly when combined with inflammation, brushing trauma or an unfavorable tooth position.
4. Tooth position and orthodontic factors
A tooth positioned toward the outer edge of the jaw may have relatively thin bone and gum covering its root. Crowded, rotated or prominent teeth can therefore be more vulnerable. Orthodontic treatment does not automatically cause recession, but existing gum thickness, bone anatomy and the planned direction of tooth movement should be considered.
5. Clenching and grinding
Clenching or grinding is not considered a simple stand-alone cause of gum recession, but heavy tooth loading may be relevant in some patients when combined with other risk factors. Your dentist may assess your bite, tooth wear and muscle symptoms as part of the overall picture.
6. Smoking and tobacco use
Smoking is a major risk factor for periodontal disease and can impair healing. It can also make gum disease harder to recognise because bleeding may be less obvious despite underlying tissue damage.
7. Plaque, calculus and other local factors
Plaque can inflame the gumline, and hardened calculus cannot normally be removed with routine brushing. Other local contributors may include traumatic oral habits, lip or tongue piercings, unusual frenum attachments, restorative margins or previous periodontal damage.
Can Receding Gum Grow Back?
Gum tissue that has been lost generally does not return to its original position by itself. However, that does not mean nothing can be done.
Depending on the cause and severity, treatment may be able to stop or slow further recession, reduce inflammation and sensitivity, protect exposed roots, improve appearance and - in selected cases - surgically cover an exposed root with gum-graft or other root-coverage procedures.
Does Every Receeding Gum Need Treatement?
No. Some small areas of recession are stable, easy to clean and not sensitive. They may only need regular monitoring. The priority is to determine whether the recession is stable or progressing and whether the exposed root is at risk.
Clinical measurements and photographs can be useful for comparing the gumline over time.
How is Gum Recession Assessed?
Your dentist will examine the gums, teeth and bite and consider the dental and medical history. Depending on the situation, assessment may include:
. Measuring the gumline and periodontal pockets with a periodontal probe
. Checking for inflammation, bleeding and loss of attachment
. X-rays to assess the bone supporting the teeth where appropriate
. Reviewing tooth position and the amount of gum tissue around the root
. Discussing brushing and interdental-cleaning technique
. Asessing the bite tooth wear and possible clenching or grinding
. Considering smoking, medicines, pervious orthodontics and previous gum treatment
How is Gum Recession Treated?
Treatment is tailored to the cause. There is no single treatment that is appropriate for every patient.
Improve brushing and home care
If brushing trauma is contributing, changing technique may be one of the most important steps. A soft-bristled toothbrush, gentle pressure and appropriate interdental cleaning are commonly recommended. Some electric toothbrushes can also warn when excessive pressure is being used.
Treat active gum disease
If periodontitis is present, controlling the disease takes priority. Treatment may involve improved daily plaque control, professional cleaning, removal of calculus, deeper periodontal cleaning where required, maintenance visits and referral to periodontist for more complex disease.
Reduce sensitivity
Exposed roots can be sensitive because they are not protected by enamel in the same way as the crown. Desensitising toothpaste, fluoride or professionally applied products may help, but sensitivity should still be assessed because decay, cracks and other dental problems can produce similar symptoms.
Protect a worn or damaged root
In selected cases, a tooth-coloured restorative material may be sued to repair a worn root surface or protect part of an exposed root. this restores the tooth surface; it does not replace the missing gum tissue.
Gum grafting / root-coverage treatement
For selected patients, gum graft surgery or another root-coverage procedure may be considered to cover an exposed root, increase gum thickness, reduce sensitivity, protect the root or improve appearance. The likely amount of root coverage depends on the anatomy and condition of the tissues around the tooth.
More complex recession may be referred to a periodontist, a dentist with advanced training in the gums and supporting tissues around the teeth.
What Happens If Gum Recession Is Left Untreated?
Some recession remains unchanged for many years; other recession continues to progress. Possible consequences can include increasing sensitivity, greater root exposure, root decay, wear of the root surface, aesthetic changes, difficulty cleaning and - when periodontitis is the cause - further loss of supporting tissue and bone.
This is why the useful clinical question is: "Why is the recession happening, and is it getting worse?"
How Can I Help Prevent Gum Recession?
- Brush gently with a soft-bristled toothbrush
- Clean between the teeth every day using floss or interdental brushes apropriate for you
- Attend regular dental examinations so changes can e compared orver time
- Treat bleeding gums and periodontal disease early
- Do not smoke or vape
- Discuss significant clenching or grinding with your dentist
- Make sure orthodontic treatmet is appropriately planed when recession or thin gum tissue is alreay present
What Toothbrush Is Best for Receding Gums?
For many patients, a soft-bristled toothbrush is appropriate. Technique and pressure are often more important than whether the brush is manual or electric. If you are unsure, bring your toothbrush to your appointment so your dental team can demonstrate how to clean the gumline effectively without excessive force.
Should I Stop Brushing Where My Gum Has Receded?
No. An area of recession still needs to be cleaned. Avoiding the area may allow more plaque to accumulate and can worsen inflammation. The goal is gentle, effective cleaning. If the area is painful or highly sensitive, ask your dentist to assess it and recommend an appropriate approach.
Can Gum Recession Cause Tooth Loss?
Mild recession by itself does not mean a tooth will be lost. However, if recession is part of advanced periodontitis with substantial loss of bone and attachment, the support around a tooth can become compromised. Early diagnosis, disease control and appropriate maintenance can make a significant difference.
When Should I See a Dentist About Receding Gums?
Arrange an assessment if you notice:
- A tooth becoming noticeably longer
- New or increasing sensitivity
- An exposed root
- Bleeding or persistently inflamed gums
- Increasing spaces between teeth
- A changing gumline
- A loose tooth
- Recession that appears to be worsening
You do not need to wait until the area becomes painful.

At Platinum Dental Studio, we assess your gum health, bone support, tooth position, brushing technique, bite, sensitivity and individual periodontal risk factors. For some patients, the best treatment is improved technique and monitoring; for others, periodontal treatment, root protection or referral for gum grafting nay be appropriate.
If you have noticed that a tooth looks longer, your gums appear to be pulling away, or you have developed sensitivity around the gumline, a dental examination can help determine what is happening.
Frequently Asked Questions
Can gums grow back after recession?
Lost gum tissue generally does not spontaneously return to its original position. However, further recession can often be controlled, and selected cases may be treated with gum grafting or another root-coverage procedure.
Is gum recession normal with age?
Recession becomes more common with age, but it should not simply be dismissed as unavoidable. The underlying cause and whether the recession is progressing should still be assessed.
Does brushing too hard cause gum recession?
Aggressive brushing can contribute to recession, especially when the gum tissue is thin or the tooth position is susceptible.
Can an electric toothbrush cause gum recession?
An electric toothbrush used correctly should not automatically cause recession. Excessive pressure or poor technique can be harmful with either an electric or manual toothbrush.
Is gum recession painful?
Not always. Many people have recession without discomfort, while others develop significant sensitivity because the root surface is exposed.
Can gum disease cause receding gums?
Yes. Periodontitis can lead to loss of the gum attachment and bone supporting the teeth, and recession may be one of the visible signs.
Can receding gums be filled?
A dentist can sometimes restore a worn or damaged exposed root with tooth-coloured filling material. This repairs the tooth surface but does not replace the missing gum.
Do I need a gum graft?
Not everyone with recession needs a graft. The decision depends on progression, sensitivity, gum thickness, tooth position, aesthetics, periodontal health and other clinical factors.
Can gum grafting cover the whole exposed root?
Sometimes excellent root coverage can be achieved, but complete coverage cannot be guaranteed in every case. Your dentist or periodontist can assess the likely result.
Can I prevent recession from becoming worse?
Often, yes. Identifying and controlling contributing factors — such as periodontal disease, brushing trauma, smoking and local irritation — can help reduce the risk of progression.
