If your teeth seem longer than they used to, you can see more of a tooth near the gumline, or certain areas have become sensitive to cold, you may be experiencing gum recession.

Gum recession happens when gum tissue moves away from its normal position around a tooth, exposing more of the tooth or its root. If you are wondering why are my gums receding, there are several possible explanations. Gum disease can contribute, but brushing habits, naturally thin gum tissue, tooth position, tobacco use, dental trauma, and other factors can also play a role.

Receding gums do not automatically mean you have advanced gum disease, and they do not necessarily mean you will lose a tooth. However, recession deserves attention because exposed root surfaces may become sensitive and more vulnerable to decay.

A dental evaluation can help determine why the gumline is changing, whether the recession appears stable or progressive, and what steps may help protect the affected teeth.

Why Are My Gums Receding?

Your gums surround and protect the roots of your teeth. When the gum margin shifts away from its previous position, part of the root can become exposed.

For some people, the first sign is visual: one tooth suddenly seems longer than the teeth around it. Others first notice sensitivity when drinking something cold, eating something sweet, brushing, or having their teeth professionally cleaned.

Recession can affect a single tooth or several areas of the mouth. It may remain relatively stable in some patients or become more noticeable over time.

One potential cause is periodontal disease. Periodontitis damages the tissues and bone supporting the teeth and can be associated with gum recession, bleeding, deeper periodontal pockets, and tooth mobility.

But periodontal disease is not the only explanation.

Your dentist will usually consider the location and pattern of recession, your gum health, brushing habits, tooth position, bite, dental history, and other risk factors before identifying likely contributors.

What Causes Gum Recession?

Gum recession is often multifactorial, meaning several factors can contribute at the same time. A 2025 systematic review found recession associated with a range of periodontal, anatomical, and potentially modifiable risk factors rather than one universal cause.

Periodontal disease

Periodontal disease is an important potential cause.

Plaque that remains around the gumline can harden into tartar and contribute to inflammation of the tissues supporting the teeth. When periodontitis progresses, supporting tissue and bone can be lost, and the gums may pull away from the teeth.

Signs that may occur alongside periodontal disease include:

• Bleeding gums
• Red or swollen gums
• Persistent bad breath
• Gum recession
• Changes in tooth position
• Loose teeth
• Discomfort while chewing

Having recession alone does not prove you have periodontal disease, but gum inflammation or bone loss makes professional evaluation particularly important.

Aggressive brushing

Patients are often told that brushing too hard can cause receding gums. The relationship is more complicated than that simple statement suggests.

Improper or aggressive brushing may traumatize gum tissue, and brushing force, bristle hardness, and brushing technique have been investigated as potential contributors. However, earlier systematic research found that the evidence establishing toothbrushing as a direct cause of non-inflammatory recession was inconclusive.

That does not mean aggressive brushing is a good idea. NIDCR recommends brushing gently with small circular motions rather than scrubbing forcefully back and forth.

Naturally thin gum tissue

People differ in the thickness and shape of their gum tissue.

Someone with naturally thin gums may be more susceptible to recession around certain teeth, particularly when other contributing factors are present. Genetics and anatomical differences are among the factors considered in research on gingival recession.

Tooth position

A tooth positioned toward the outside of the dental arch may have thinner gum and bone covering part of its root.

Tooth alignment and previous orthodontic movement may therefore be considered during a recession evaluation. This does not mean orthodontic treatment automatically causes gum recession; the relationship depends on the patient’s anatomy, tooth movement, periodontal health, and other factors.

Tobacco use

Smoking and smokeless tobacco can negatively affect periodontal health. Tobacco use is also an important risk factor for gum disease and can interfere with healing following periodontal treatment.

Oral piercings or repeated trauma

Jewelry in the lip or tongue may repeatedly rub against gum tissue near certain teeth, potentially contributing to localized recession. Other forms of repeated mechanical trauma can also affect the gumline.

Grinding, clenching, and bite forces

Patients sometimes assume that teeth grinding directly causes their gums to recede.

Research suggests excessive or abnormal bite forces may be associated with recession in some circumstances, but recession usually should not be attributed to grinding without an examination. A recent meta-analysis identified occlusal trauma as one factor associated with gingival recession, alongside periodontal and anatomical factors.

If your dentist sees tooth wear, fractures, bite changes, or other evidence of excessive forces, those findings may become part of the overall evaluation.

What Are the Stages and Signs of Receding Gums?

Gum recession does not always progress through a simple set of stages that patients can diagnose at home.

Dentists can classify recession based on clinical measurements and factors involving the gum tissue, attachment, and supporting structures. For everyday understanding, however, it can be helpful to think of recession as becoming more noticeable or extensive over time rather than trying to assign yourself a stage.

Early or mild recession

Early changes may be subtle.

You might notice:

• One tooth beginning to look longer
• A slight change in the gumline
• Mild sensitivity around the gumline
• A small amount of visible root surface

At this point, determining the cause can help reduce avoidable factors that might allow the recession to progress.

More noticeable recession

As additional root surface becomes exposed, you may experience:

• Increased cold sensitivity
• Sensitivity to sweets
• Discomfort while brushing
• A clearly visible difference between neighboring gumlines
• A notch or change near the tooth root

Exposed roots can also be more vulnerable to decay because they do not have the same protective enamel covering as tooth crowns.

Recession with other periodontal changes

Recession becomes more concerning when it occurs alongside signs such as:

• Frequent gum bleeding
• Swelling or tenderness
• Deep spaces between the teeth and gums
• Persistent bad breath
• Bone loss
• Loose or shifting teeth

These symptoms may indicate that the problem involves more than isolated recession. NIDCR notes that periodontal disease can cause gums to pull away from teeth and, in advanced cases, damage the supporting bone enough to cause tooth mobility.

The amount of visible recession alone does not tell the whole story. Your dentist needs to consider the health of the surrounding gums and bone as well.

Can Receding Gums Grow Back?

Once gum tissue has been lost through recession, it generally does not simply grow back to its original position on its own.

That distinction is important because products marketed as being able to “regrow” receded gums can create unrealistic expectations.

However, not being able to naturally regrow lost tissue does not mean the condition cannot be managed.

Treatment may help:

• Reduce additional recession
• Control periodontal inflammation
• Protect exposed root surfaces
• Reduce sensitivity
• Improve the ability to keep the area clean
• Cover exposed roots in selected cases

For mild or stable recession, monitoring and correcting contributing factors may be enough. More significant recession may benefit from periodontal procedures such as gum grafting.

A gum graft involves placing tissue in an area where the gumline has receded to reinforce the tissues or cover an exposed root. Whether grafting is appropriate depends on the location, severity, periodontal health, anatomy, and patient’s individual goals.

How Are Receding Gums Treated?

Treatment should address why the recession happened, not simply the fact that the gumline looks different.

That means two patients with similar-looking recession may receive different recommendations.

Monitoring mild, stable recession

Some areas of mild recession do not require surgical treatment.

If your dentist determines that the area is healthy and stable, the plan may include improving brushing technique, controlling plaque, managing sensitivity, and monitoring the gumline at future visits.

Treating periodontal disease

When periodontal disease contributes to recession, controlling the underlying infection and inflammation becomes the priority.

Treatment may include scaling and root planing to remove plaque and tartar below the gumline. More advanced periodontal disease may require additional procedures depending on the amount of tissue and bone involvement.

Managing sensitivity

Exposed roots can become sensitive because the root surface is not protected by the same enamel covering as the crown.

Depending on your needs, your dentist may recommend:

• Desensitizing toothpaste
• Fluoride treatments
• Other desensitizing products
• Tooth-colored bonding in selected areas

These approaches may improve comfort, but they do not cause lost gum tissue to regenerate.

Adjusting contributing habits

If brushing technique is irritating the area, your dental team may recommend a soft-bristled toothbrush and gentler technique.

If other factors such as tobacco use, a piercing, tooth position, or abnormal bite forces appear relevant, treatment recommendations may address those factors as well.

Gum grafting

When recession is significant, progressing, difficult to keep comfortable, or creating concern about an exposed root, gum grafting may be considered.

Gum graft procedures add tissue around the affected area. They are commonly performed by periodontists and can help cover exposed root surfaces and increase tissue thickness in appropriate cases.

Not everyone with recession needs a gum graft. Your dentist or periodontist can explain whether the expected benefit justifies treatment in your particular situation.

How Can You Help Prevent Further Gum Recession?

Some risk factors for gum recession cannot be completely controlled, particularly individual anatomy or naturally thin gum tissue. But good daily habits can help protect your gums and reduce avoidable inflammation or trauma.

• Brush twice a day with fluoride toothpaste. Clean thoroughly without scrubbing aggressively.
• Use a soft-bristled toothbrush. Gentle brushing can remove plaque without unnecessary force against the gumline.
• Clean between your teeth every day. Floss or another appropriate interdental cleaner helps remove plaque where your toothbrush cannot easily reach.
• Avoid forcing floss into the gums. Guide it gently between the teeth and curve it around the sides of each tooth.
• Keep plaque under control. Plaque that remains on teeth can harden into tartar, which requires professional removal and can contribute to periodontal inflammation.
• Avoid tobacco. Smoking and other tobacco use are important periodontal risk factors.
• Pay attention to grinding or clenching symptoms. Mention jaw soreness, tooth wear, fractures, or suspected nighttime grinding during your dental visit rather than assuming these forces are harmless.
• Do not ignore bleeding gums. Persistent bleeding may indicate inflammation and deserves evaluation.
• Maintain regular professional care. Preventive Dentistry can help your dental team monitor the gumline, remove hardened deposits, and identify changes before they become more extensive.

If you already have recession, the most useful prevention strategy is individualized. Understanding the cause helps determine what should be changed and what does not need to change.

When Should You See a Dentist?

You do not need to wait until gum recession becomes painful.

Schedule a dental evaluation if you notice:

• A tooth beginning to look longer
• Increasingly visible tooth roots
• A gumline that continues to change
• Persistent sensitivity near the roots
• Bleeding gums
• Red, swollen, or tender gums
• Pain while brushing or chewing
• Persistent bad breath
• Teeth beginning to shift
• A loose permanent tooth
• Difficulty keeping an exposed root clean
• Changes around existing dental work

A dentist or dental hygienist can examine your gums and measure the tissues around your teeth with a periodontal probe. If gum disease is suspected, dental X-rays may also be used to evaluate supporting bone.

For patients in Tooele, having recession evaluated while it is still mild can help establish a baseline. Your dental team can then determine whether the gumline appears stable at future visits or is continuing to change.

Persistent recession, sensitivity, or bleeding should not simply be watched indefinitely at home. Knowing the cause is the first step toward choosing appropriate care.

FAQs

Is gum recession always caused by gum disease?

No. Periodontal disease is an important cause of recession, but brushing habits, tooth position, naturally thin gum tissue, tobacco use, trauma, and other factors can also contribute. Gum recession is considered a multifactorial condition, which is why professional evaluation is useful.

Can receding gums grow back naturally?

Lost gum tissue generally does not simply grow back to its previous position. Treatment can help manage the condition and limit progression, while gum grafting may restore coverage over an exposed root in selected cases.

Can brushing too hard cause gums to recede?

Aggressive brushing can irritate or traumatize gum tissue, and brushing-related factors have been associated with recession. However, research does not support assuming that every case of recession is directly caused by brushing. Using a soft-bristled brush and gentle technique is still recommended.

Why are my receding gums making my teeth sensitive?

Recession can expose the tooth root. Root surfaces do not have the same thick enamel protection as tooth crowns, so temperature, sweets, brushing, or touch may produce sensitivity.

Do all receding gums need surgery?

No. Mild, stable recession may be managed through monitoring, improved oral hygiene, sensitivity management, or treatment of contributing factors. More significant recession may require periodontal procedures such as gum grafting.

What happens if gum recession keeps getting worse?

Progressive recession can expose more of the tooth root, increasing sensitivity and making root decay more likely. If the recession is associated with periodontitis, supporting tissue and bone may also be affected.
