Receding Gums: Causes, Treatment, and When You Need a Gum Graft

Featured Specialist: Dr. Mitchell Gubler

Gum recession happens when the gum tissue around a tooth pulls back, exposing more of the tooth’s root. It’s commonly caused by aggressive brushing, periodontal disease, genetics, teeth grinding, and tobacco use. Mild recession can sometimes be managed with changes at home, but when recession exposes the root to ongoing sensitivity or decay risk, a gum graft is often the most effective way to restore protection and stop it from getting worse.

What Causes Receding Gums?

Recession rarely has a single cause — it’s usually the result of one or more ongoing habits or conditions wearing down the gum tissue over time. The most common contributors include:

• Aggressive brushing: Brushing too hard or using a hard-bristled toothbrush can gradually wear away gum tissue, especially along the outer surfaces of the teeth.
• Periodontal disease: Gum disease breaks down the tissue and bone that support your teeth, and recession is one of the most visible results of that process.
• Genetics: Some patients are simply born with thinner gum tissue or teeth positioned in a way that makes recession more likely, regardless of how carefully they care for their teeth.
• Teeth grinding or clenching: Excess force on the teeth, especially during sleep, can contribute to gum and bone loss around the affected teeth over time.
• Tobacco use: Tobacco products are linked to a higher risk of gum disease and can interfere with the health and healing of gum tissue.

Because several of these causes can overlap, your periodontist will typically look at your brushing habits, bite, tissue thickness, and any signs of gum disease together before recommending a treatment approach.

Why Does Gum Recession Matter Beyond Appearance?

It’s easy to think of receding gums as a cosmetic issue, and for some patients, appearance is the main concern. But recession also exposes the root surface of the tooth, which isn’t protected by the same hard enamel that covers the crown of the tooth. That exposed root is more vulnerable in a few important ways:

• Increased sensitivity: Exposed roots often react to hot, cold, or sweet foods and drinks, sometimes significantly more than the rest of the tooth.
• Higher risk of root decay: Root surfaces are softer than enamel and more susceptible to cavities once exposed.
• Greater vulnerability to further gum and bone loss: Once tissue has receded, that area often has less protection against further irritation, making continued recession more likely without intervention.

This is why recession is worth evaluating even when it isn’t bothering you cosmetically — the underlying exposure can create problems long before you notice pain or a visible change in your smile.

Is My Gum Recession Just Cosmetic, or a Sign of a Bigger Problem?

Not every case of gum recession requires immediate treatment. Mild, stable recession — especially when it’s caused by a brushing habit that’s since been corrected, or by naturally thin tissue that isn’t accompanied by inflammation or bleeding — may simply need monitoring. Your periodontist can track it at routine visits to confirm it isn’t progressing.

Recession is more likely to signal an active problem when it’s accompanied by bleeding, tenderness, or inflammation, when pocket depths around the tooth are increasing, when the recession is progressing noticeably over time, or when it’s affecting multiple teeth in a pattern consistent with periodontal disease. As with other stages of gum disease, catching these active cases early — as discussed in our guide to gum disease treatment — gives you more options and typically means less invasive treatment.

What Nonsurgical Steps Can Help Early Gum Recession?

When recession is caught early and isn’t yet severe, some steps can help slow or stabilize it without surgery:

• Switching to a soft-bristled toothbrush and gentler technique: Reducing the force and abrasiveness of brushing can prevent further mechanical wear on the gum tissue.
• Treating underlying gum disease: If periodontal disease is driving the recession, treatment such as scaling and root planing addresses the infection that’s damaging the tissue.
• Addressing teeth grinding: A nightguard or other bite management approach can reduce the ongoing forces contributing to tissue and bone loss.
• Improving overall oral hygiene consistency: Reducing plaque buildup along the gumline helps prevent the inflammation that can accelerate recession.

These measures can be effective for stabilizing mild recession, but they don’t rebuild tissue that has already been lost. Once the root is significantly exposed or the recession keeps progressing despite these changes, a gum graft becomes the more reliable long-term solution.

What Does a Gum Graft Involve?

Gum grafting restores lost soft tissue volume and health around a tooth by adding tissue to the area where gum has receded. It’s recommended when recession has progressed enough that nonsurgical steps alone won’t resolve it — typically when a patient has significant root exposure, ongoing sensitivity, a higher risk of root decay, or recession that continues to worsen despite corrected habits.

The procedure rebuilds the band of protective tissue around the tooth, which helps shield the root from further wear, reduces sensitivity, and can improve the appearance of the gumline. Because every patient’s recession pattern, tissue thickness, and goals are different, your periodontist will evaluate your specific case — including how many teeth are affected and how advanced the recession is — before recommending the right approach for your grafting procedure.

Dr. Gubler, our board certified periodontist and a Diplomate of the American Board of Periodontology, brings additional depth to grafting cases through his graduate research on bone grafting prior to implant placement, for which he received a first-place research award from the Iowa Section of the American Association for Dental Research. He is also licensed in IV sedation and ACLS certified, and works alongside DAANCE-certified surgical assistants, so patients who need extra comfort during treatment have that option available.

What Is Recovery Like After a Gum Graft?

Recovery after gum grafting generally follows the same pattern as other minor periodontal surgical procedures. Most patients experience some swelling and tenderness in the treated area for the first few days, which typically improves with time and any aftercare instructions provided by your periodontal team. A soft diet and gentle oral hygiene around the treatment site are usually recommended during initial healing, with a gradual return to normal brushing and eating as the tissue settles. Your periodontist will give you a specific timeline based on the size and location of your graft, along with guidance on activity and any temporary restrictions during the healing period.

Benefits of Treating Gum Recession Early

Why address recession before it becomes severe?

• Less invasive treatment options: Catching recession early often means nonsurgical steps or a smaller graft can resolve the issue, rather than a more extensive procedure later.
• Reduced risk of root decay: Protecting exposed roots sooner lowers the chance of developing cavities in an area that’s harder to treat than a typical tooth surface.
• Preserved bone and tissue support: Addressing the underlying cause — whether it’s brushing technique, grinding, or gum disease — helps prevent further loss of the structures that keep your teeth stable.
• A healthy, confident, beautiful smile: Treating recession protects both the function and appearance of your smile, so you’re not managing sensitivity or self-consciousness about your gumline down the road.

If you’ve noticed your gums pulling back, increased sensitivity, or teeth that look longer than they used to, it’s worth having a periodontist evaluate the cause before it progresses further. Our team can determine whether your recession needs monitoring, nonsurgical care, or a gum graft, and build a treatment plan around your specific case. Schedule a consultation to get a clear picture of your gum health and the options available to you.

Frequently Asked Questions

Do receding gums grow back on their own?

No. Once gum tissue has receded away from the tooth, it does not grow back naturally, even if the underlying cause is corrected. Stopping the progression through better habits or treating gum disease can prevent further recession, but restoring lost tissue requires a procedure like gum grafting.

Is a gum graft painful?

Gum grafting is performed with local anesthesia, so the procedure itself is not painful. Some soreness and swelling in the days after treatment are common and are generally manageable with the aftercare guidance your periodontist provides.

How do I know if my gum recession needs treatment?

Signs that recession needs evaluation include increasing tooth sensitivity, visible lengthening of the teeth, bleeding or inflammation, and recession that seems to be getting worse over time. A periodontal evaluation can measure the extent of recession and determine whether monitoring, nonsurgical care, or grafting is the right next step.

Can you prevent gum recession?

You can lower your risk by brushing gently with a soft-bristled brush, treating gum disease promptly, managing teeth grinding, and avoiding tobacco use. Genetics also play a role, so some patients may experience recession despite good habits, which is why regular dental checkups are important for catching it early.

Does gum recession always require a graft?

Not always. Mild or stable recession that isn’t accompanied by sensitivity, disease, or ongoing progression may only need monitoring or nonsurgical steps. A gum graft is generally recommended when recession is more advanced or continues to worsen despite those measures.

Can receding gums cause tooth loss?

Recession itself is a symptom rather than a direct cause of tooth loss, but the underlying conditions that cause it, particularly periodontal disease, can lead to loss of the bone and tissue that support the tooth if left untreated. Addressing recession and its cause early helps protect the long-term stability of the tooth.

Will insurance cover a gum graft?

Coverage varies by plan and often depends on whether the recession is documented as a health issue rather than a purely cosmetic concern. Our team can help review your specific case and discuss your options during a consultation before you move forward with treatment.
