Why Are My Gums Receding Around One Tooth?
Gum recession around one tooth can make the tooth appear longer, expose part of the root or create sensitivity near the gum line. The cause may relate to brushing habits, gum inflammation, tooth position, thin gum tissue or other local factors, so identifying the reason is important before deciding how the area should be managed.
Why gum recession may affect only one tooth, how tooth position, brushing pressure, periodontal problems and thin gum tissue can contribute, why an exposed tooth root may become sensitive, whether recession can grow back and when the area should be assessed.
Gum recession around one tooth means the gum margin has moved away from its previous position, exposing more of the tooth or part of the root surface.
Some patients first notice that one tooth looks longer than the others.
Others notice sensitivity, a visible line near the gum, a darker or more yellow root surface or a small space that was not previously there.
A receding gum on one tooth does not automatically mean that the patient has severe gum disease.
Recession can have several causes, and sometimes more than one factor is present at the same time.
A dental check-up can help determine whether the recession is stable or whether there are signs of active gum, tooth or bite-related problems.
What Is Gum Recession?
Gum recession occurs when the margin of the gum moves further away from the crown of the tooth.
This can expose part of the root surface that would normally be covered by gum tissue.
Because tooth roots do not have the same enamel covering as the crown, exposed root surfaces can behave differently.
They may look more yellow, feel more sensitive and can be more vulnerable to root-surface wear or decay in some patients.
Why Can Gum Recession Affect Only One Tooth?
Gum recession does not always affect the entire mouth evenly.
A single tooth may be positioned differently from its neighbours, may receive different brushing pressure or may have thinner supporting gum and bone around it.
Local plaque accumulation, a restoration near the gum line or previous trauma can also affect one area more than another.
This means receding gums on one tooth should be assessed according to the specific tooth rather than assuming the same explanation applies everywhere in the mouth.
What Causes Gum Recession Around One Tooth?
There is no single cause of gum recession.
Possible contributing factors include:
- Excessive brushing pressure
- Using a brushing technique that repeatedly traumatizes one area
- Thin gum tissue around the tooth
- A tooth positioned toward the outside of the dental arch
- Periodontal inflammation or gum disease
- Plaque and calculus accumulation
- Previous orthodontic tooth movement
- Local trauma
- Grinding or other mechanical factors in selected cases
- Restorations extending close to the gum margin
- Changes in the supporting bone around the tooth
The visible recession itself does not reveal which of these factors is responsible.
The tooth position, gum thickness, plaque levels, periodontal measurements and surrounding tissues all need to be considered.
Can Brushing Too Hard Cause a Receding Gum on One Tooth?
Repeated mechanical trauma from brushing can contribute to recession in some patients.
This is more likely when the gum tissue is already thin or when one tooth sits more prominently toward the cheek or lip.
However, seeing recession does not automatically prove that brushing too hard is the cause.
Gum disease, tooth position and tissue anatomy should also be considered.
A receding gum should not automatically be blamed on brushing. The reason the gum changed matters more than the appearance alone.
Can Gum Disease Cause Recession Around One Tooth?
Yes.
Periodontal disease can damage the tissues that support the teeth, including the gum and underlying bone.
As this support changes, the gum margin may recede.
Periodontal recession may be accompanied by other findings such as bleeding, deeper periodontal pockets, plaque, calculus or bone loss.
However, not every recessed gum is caused by periodontitis.
This distinction is important because the treatment for active gum disease is different from the management of a stable recession defect caused mainly by anatomy or trauma.
Find Out Why the Gum Has Receded
Gum recession can have several causes. Assessing the gum, tooth position, plaque levels and supporting tissues helps determine whether the area simply needs monitoring or active treatment.
Can the Position of a Tooth Cause Gum Recession?
Yes.
Teeth are surrounded by a limited amount of supporting bone and gum.
If a tooth sits prominently toward the lip or cheek side of the dental arch, the tissue covering the outer surface may be relatively thin.
Thin tissue may be more vulnerable to recession than thicker tissue.
Tooth position is therefore an important part of assessing isolated gum recession.
Can Orthodontic Treatment Affect Gum Recession?
Orthodontic treatment itself does not automatically cause recession.
However, the relationship between tooth movement, bone boundaries and gum thickness can be important.
Moving a tooth within appropriate biological limits may be well tolerated, while teeth with very thin tissues may require closer periodontal observation.
Previous orthodontic treatment should therefore be included in the dental history when a patient develops recession around a specific tooth.
Why Does an Exposed Tooth Root Look Yellow?
An exposed tooth root may look more yellow than the enamel-covered portion of the tooth.
This does not necessarily mean the root is dirty or decayed.
Root surfaces naturally have a different colour and structure from enamel.
Once recession exposes the root, the colour difference may become more noticeable.
Can Gum Recession Make One Tooth Sensitive?
Yes.
When the root surface becomes exposed, the tooth may become more sensitive to cold, brushing, air or certain foods.
This happens because the root does not have the same enamel protection as the crown of the tooth.
Sensitivity associated with recession is often short and triggered by a stimulus.
Persistent spontaneous pain or prolonged temperature sensitivity should not automatically be attributed to the recession because cavities, cracks and pulpal problems can also cause pain.
Can an Exposed Root Develop a Cavity?
Yes.
Root surfaces can develop dental caries, particularly when plaque accumulates and other risk factors are present.
Because the root surface differs from enamel, root caries can progress differently from decay affecting the crown of the tooth.
Good plaque control and appropriate preventive care become especially important when the root is exposed.
Can Teeth Cleaning Help With Gum Recession?
Professional cleaning may be important when plaque, calculus or gum inflammation is present.
Removing these deposits can help control inflammation and improve the patient’s ability to maintain the area.
However, professional teeth cleaning does not physically move an already-receded gum margin back to its previous position.
The purpose of cleaning is to control the disease or inflammation contributing to the problem when these factors are present.
Can Receding Gums Grow Back Naturally?
Gingival recession generally does not predictably reverse itself simply by changing toothpaste or brushing technique.
Controlling the factor that contributed to recession may help prevent further progression.
For example, improving brushing technique or treating gum inflammation can help protect the area.
In selected cases where root coverage is desired, periodontal surgical procedures may be considered after appropriate assessment.
Whether this is necessary depends on symptoms, recession size, tissue anatomy, periodontal health and patient priorities.
Does Gum Recession Always Need Treatment?
No.
Some areas of recession remain stable for years and may only require appropriate cleaning and monitoring.
Treatment becomes more relevant when recession is progressing, sensitivity is significant, root decay develops, plaque control is difficult or the patient has an aesthetic concern.
The cause should be controlled before considering cosmetic correction.
Can a Filling Be Used on an Exposed Tooth Root?
Sometimes.
A tooth-coloured restoration may be considered if an exposed root has developed a cavity, significant wear or a structural defect.
In selected cases, restorative material may also help manage sensitivity.
However, placing a filling does not treat the cause of gum recession.
If the root surface is healthy and intact, adding restorative material may not be necessary.
How Should You Brush a Tooth With Gum Recession?
The area still needs to be cleaned effectively.
Avoiding brushing completely because the tooth is sensitive can allow more plaque to accumulate.
A soft toothbrush and controlled brushing technique can help clean the gum line while limiting unnecessary trauma.
The ideal technique may vary depending on the patient’s gum condition and dexterity, so personalized instruction can be useful.
Can Sensitivity Toothpaste Help an Exposed Root?
Desensitizing toothpaste can help reduce root sensitivity for some patients.
These products may contain ingredients designed to reduce transmission of sensitivity through exposed dentin.
They do not cause the gum to grow back, but they may make an exposed root more comfortable while the underlying cause is being managed.
Can Gum Recession Cause Food to Get Stuck Between Teeth?
It can.
The gum tissue between neighbouring teeth normally fills part of the space beneath the contact point.
If this tissue recedes or changes shape, the space can become larger and food may collect more easily.
Tooth position and contact between the teeth also influence food trapping.
Why Is There a Dark Triangle Near the Receding Gum?
A dark triangular space may appear when the gum tissue between two teeth does not completely fill the area beneath the contact point.
The dark appearance is often the shadow of the space rather than a black stain on the tooth.
Gum recession, periodontal changes, tooth shape and tooth position can all contribute.
Treatment depends on the reason the space developed, so simply adding filling material is not appropriate in every case.
Should a Receding Gum Bleed?
Recession itself does not necessarily cause bleeding.
Bleeding more often suggests inflammation, plaque accumulation, periodontal disease or mechanical trauma to the tissue.
A recessed area that repeatedly bleeds during normal brushing should therefore be assessed rather than assuming the bleeding is simply because the gum has moved.
Why Does the Gum Around One Tooth Feel Sore?
Localized soreness can have several causes.
The gum may be inflamed because of plaque, food trapping or trauma.
There may also be a periodontal pocket, a local restoration issue or another dental problem in the area.
Pain from the tooth itself can sometimes be mistaken for gum pain.
If discomfort persists, the tooth and surrounding gum should both be examined.
Will Gum Recession Keep Getting Worse?
Not necessarily.
Some recession defects become stable once contributing factors are controlled.
Others may progress if periodontal disease, repeated trauma or another underlying factor remains active.
Monitoring the gum margin over time is useful because progression is more important clinically than the presence of a small stable recession alone.
How Does a Dentist Check Gum Recession?
Assessment usually involves examining the gum margin and the supporting tissues around the tooth.
The examination may include:
- Measuring the amount of recession
- Checking periodontal pocket depths
- Assessing gum inflammation and bleeding
- Checking plaque and calculus levels
- Looking at the position of the tooth
- Assessing the thickness and quality of the gum tissue
- Checking for root wear or root caries
- Evaluating nearby restorations
- Assessing the patient’s brushing technique
- Taking dental X-rays when clinically indicated
How Is Gum Recession Around One Tooth Treated?
Treatment depends on the cause and severity.
Management may include:
- Improving brushing technique
- Controlling plaque and gum inflammation
- Professional dental cleaning when indicated
- Managing periodontal disease
- Treating root sensitivity
- Restoring root cavities or structural defects
- Monitoring stable recession
- Periodontal referral when surgical root coverage may be appropriate
There is no benefit in treating the appearance alone while ignoring an active cause.
Can Gum Recession Be Prevented?
Not every case can be completely prevented because anatomy and tooth position also influence gum stability.
Helpful preventive measures include:
- Using an appropriate brushing technique
- Avoiding excessive brushing pressure
- Cleaning between the teeth regularly
- Controlling plaque accumulation
- Attending regular dental examinations
- Treating gum inflammation early
- Monitoring areas with thin gum tissue
When Should Gum Recession Around One Tooth Be Checked?
A dental examination is particularly useful when the recession is new, changing or causing symptoms.
Consider having the area assessed if:
- One tooth appears noticeably longer than before
- The gum margin appears to be moving downward or upward
- You can see an exposed tooth root
- The tooth has developed new sensitivity
- The gum repeatedly bleeds
- Food becomes trapped around the area
- The root surface looks damaged or cavitated
- The gum is painful or swollen
- The tooth feels mobile
- The recession appears to be progressing

Conclusion: Why Are My Gums Receding Around One Tooth?
Gum recession around one tooth can occur for several reasons.
Brushing trauma, tooth position, thin gum tissue, periodontal disease, plaque accumulation and local anatomical factors may all contribute.
A receding gum on one tooth does not automatically mean severe gum disease, but it should not automatically be assumed to be harmless either.
If a gum is pulling away from a tooth, the cause should ideally be identified before deciding whether treatment is needed.
An exposed tooth root can also become sensitive or develop root-surface decay in some patients.
Stable recession may sometimes only require monitoring and good preventive care, while progressive recession or active periodontal disease may need additional treatment.

Frequently Asked Questions
Common questions about receding gums, exposed tooth roots, sensitivity and gum recession around individual teeth.
Why is my gum receding around only one tooth? +
Isolated recession may be related to tooth position, thin gum tissue, brushing trauma, periodontal inflammation or another local factor. The specific area should be assessed to determine the cause.
Can brushing too hard cause gum recession? +
Repeated excessive brushing pressure can contribute to recession, particularly where the gum is thin, although other causes such as periodontal disease and tooth position should also be considered.
Does gum recession mean I have gum disease? +
Not necessarily. Gum disease is one possible cause, but recession can also be associated with anatomy, tooth position and mechanical trauma.
Can receding gums grow back? +
Receded gum tissue does not usually predictably return to its previous position by itself. Controlling the cause may help prevent progression, and selected cases may be suitable for periodontal root-coverage procedures.
Why does an exposed tooth root look yellow? +
The root surface naturally differs in colour from enamel and may look more yellow once gum recession exposes it.
Can an exposed root make a tooth sensitive? +
Yes. Exposed root surfaces can become sensitive to cold, air, brushing or certain foods because they do not have the same enamel covering as the crown of the tooth.
Can an exposed tooth root get a cavity? +
Yes. Root surfaces can develop dental caries, particularly when plaque accumulates and other decay risk factors are present.
Will professional cleaning fix gum recession? +
Cleaning can help control plaque, calculus and gum inflammation, but it does not physically move an already-receded gum margin back to its previous position.
Does every receding gum need treatment? +
No. Stable recession may only require monitoring and preventive care. Treatment becomes more relevant if recession progresses, causes sensitivity, develops root decay or creates another clinical concern.
Can a filling cover an exposed tooth root? +
A restoration may be considered when the root has decay, wear or another structural defect. A healthy exposed root does not automatically need to be covered with filling material.
Why is there a dark triangle near my receding gum? +
The dark appearance may represent an open space where the gum tissue no longer completely fills the area between the teeth. Gum recession, tooth shape and tooth position can contribute.
Can gum recession get worse over time? +
It can, particularly when an active contributing factor remains. Other recession defects remain stable once the cause is controlled.
When should I see a dentist about a receding gum? +
An assessment is useful if the recession is new, progressing, sensitive, bleeding, associated with root damage or accompanied by other changes around the tooth.
Where can I have gum recession checked in Abu Dhabi? +
Dr. Zinab provides general and preventive dental assessment in Al Mushrif, Abu Dhabi, including evaluation of localized gum recession, exposed roots and gum-related concerns.
