What This Guide Covers and Who It Is For
This guide explains why gum recession can affect just one tooth and what you can do about it. It is written for anyone who has noticed a single tooth looking longer than the teeth next to it, or who feels a notch near the gumline with their tongue.
Gum recession means the gum tissue has pulled away from the tooth, exposing part of the root. When it happens on one tooth while the rest of your gums look healthy, there is almost always a specific, identifiable reason. Understanding that reason is the first step toward fixing the problem.
Below you will find information on causes, treatment options, costs, recovery, and when to see a periodontist, a dentist who specializes in the gums and the bone that supports teeth. You can learn more about what periodontists do on the periodontics page.
Why Gum Recession Happens on Just One Tooth
Single-tooth recession is typically caused by a local factor affecting that one site, not by widespread gum disease. Identifying the exact cause helps your periodontist choose the right treatment and prevent the problem from coming back. Research confirms that anatomical predisposing factors, such as thin tissue and tooth position, play a central role in localized recession. [4]
Aggressive Brushing and Abrasion
Brushing too hard or using a stiff-bristled toothbrush can wear away gum tissue over time. This is called toothbrush abrasion. It most often affects the canines and premolars on the side of your dominant hand, because that hand tends to apply more pressure.
The damage builds up gradually. You may not notice it until the root surface becomes visible or sensitive. Switching to a soft-bristled brush and using gentle, circular strokes can slow or stop further recession. The American Dental Association recommends soft-bristled brushes for everyday use. [3]
Tooth Position in the Arch
A tooth that sits further forward than its neighbors is called a labially positioned tooth. This forward position means the bone covering the root is thinner than normal. In some cases, the bone is so thin that it does not fully support the overlying gum tissue. [4]
When thin bone and thin gum tissue combine, even normal brushing forces can trigger recession on that one tooth. This is why orthodontic treatment sometimes precedes or follows gum grafting. Moving the tooth into better alignment can reduce the risk of future recession.
Thin Gum Tissue (Tissue Biotype)
Gum tissue thickness varies from person to person. A thin tissue biotype means the gums are naturally delicate and more vulnerable to recession. You can sometimes tell you have thin tissue if your gums appear translucent or if you can see the outline of the tooth root through them.
Thin tissue biotype is genetic. It does not mean you have gum disease. It does mean that certain teeth, especially those in prominent positions, carry a higher risk of localized recession. [4]
Frenum Pull
A frenum is a small fold of tissue that connects the lip or cheek to the gum. If a frenum attaches close to the gumline of a particular tooth, it can tug on the gum tissue every time you talk, eat, or smile. Over time, this repetitive pulling can cause recession on that tooth.
A procedure called a frenectomy removes or repositions the frenum. A periodontist often performs a frenectomy at the same time as a gum graft to address both the cause and the damage.
Localized Periodontal Disease
While single-tooth recession is usually not caused by generalized gum disease, it is possible for periodontal disease to affect one site more than others. A deep pocket of bacteria around one tooth can destroy the bone and gum tissue at that specific location. [2]
Your periodontist will measure pocket depths around the affected tooth to rule this out. If localized infection is present, treating the infection comes first. Grafting is only appropriate once the infection is controlled.
What You Should Know Before Getting Treatment
Treating single-tooth recession is most effective when it is done early, before the recession becomes severe. Here are practical details about timing, preparation, and treatment options.
How Recession Severity Is Measured
Periodontists classify recession using a system called the Miller Classification or the newer Cairo Classification. These systems describe how much tissue has been lost and whether the bone between teeth (interdental bone) is intact.
When the interdental bone is still present, the chances of full root coverage with a graft are higher. However, outcomes vary widely depending on the initial severity of the recession. A systematic review from the AAP Regeneration Workshop found that while connective tissue grafts achieved high levels of average root coverage, the rate of complete root coverage ranged from 20 percent to 95 percent depending on factors such as the recession class and study design. [5] This wide range highlights why early treatment matters. The less recession present at the time of surgery, the more likely it is that the graft will fully cover the exposed root. When interdental bone has been lost, only partial coverage may be possible.
Treatment Options for a Single Tooth
The most common treatment is a connective tissue graft (CTG). The periodontist takes a small piece of tissue from under the surface of the roof of your mouth (the palate) and stitches it over the exposed root. This provides a thick, durable layer of new tissue. A Cochrane systematic review concluded that connective tissue grafts produce the best outcomes for root coverage compared with other graft materials. [5]
An alternative is an acellular dermal matrix (ADM), which is processed donor tissue. ADM avoids the need for a palatal donor site, which can reduce discomfort. However, some research suggests that connective tissue grafts from your own palate may produce slightly thicker tissue and more predictable long-term results. [5] Evidence is mixed on whether the difference is clinically significant in every case, and your periodontist can help you weigh the trade-offs.
A third option is the pinhole surgical technique, a minimally invasive method where the periodontist repositions existing gum tissue through a small hole rather than making incisions. This technique works best for mild to moderate recession and is not appropriate in every case. Your periodontist will recommend the approach that fits your anatomy and the severity of your recession.
When to Treat and Does Age Matter
There is no strict age requirement for a gum graft. Adults of any age can be candidates as long as they are in generally good health and do not have uncontrolled periodontal disease.
The best time to treat is when recession is first noticed and the cause has been identified. If the cause is not addressed first, such as switching to a softer brush or correcting a frenum pull, the graft may fail or recession may return.
How to Prepare for a Gum Graft
Your periodontist will start with a thorough exam, including X-rays and pocket depth measurements. If any plaque or tartar buildup is present, a professional cleaning may be scheduled before the graft.
On the day of the procedure, eat a light meal beforehand. You will receive local anesthesia, so you will be awake. If you have dental anxiety, ask about sedation options. Plan for someone to drive you home if sedation is used.
Risks and Limitations of Gum Grafting
Gum grafting is a safe and well-studied procedure, but no surgery is without risk. Possible complications include bleeding, infection at the graft or donor site, graft failure (where the new tissue does not survive), and pain or swelling that lasts longer than expected.
Smoking significantly increases the risk of graft failure. If you smoke, your periodontist may strongly recommend quitting before the procedure. Uncontrolled diabetes and certain blood-thinning medications can also affect healing. Be sure to share your full medical history with your periodontist during the evaluation.
Complete root coverage is not guaranteed in every case. The systematic review by Chambrone and Tatakis found that complete root coverage rates for connective tissue grafts ranged from as low as 20 percent to as high as 95 percent, depending on the recession severity and study conditions. [5] The likelihood of full coverage depends on the recession classification, the amount of remaining bone, and patient-specific factors such as tissue thickness and oral hygiene habits. Your periodontist will discuss realistic expectations during your consultation.
What to Expect During and After a Gum Graft
A single-tooth gum graft is an outpatient procedure that typically takes 60 to 90 minutes from start to finish.
During the Procedure
The periodontist numbs the area around the affected tooth and the donor site on your palate, if a connective tissue graft is being used. You should feel pressure but no pain.
The periodontist gently prepares the gum tissue around the receded tooth, creating a small pouch or flap. The graft tissue is placed over the exposed root and secured with tiny sutures. The donor site on the palate is also closed with sutures or covered with a protective dressing.
If acellular dermal matrix is used instead, there is no palatal donor site. The procedure is otherwise similar.
The First Week of Recovery
Swelling and mild discomfort are normal for the first two to three days. Most patients manage pain with over-the-counter medications such as ibuprofen or acetaminophen. Your periodontist may prescribe a stronger medication for the first day or two.
Eat soft, cool foods for the first week. Avoid chewing near the graft site. You will also avoid brushing and flossing at the surgical area. A chlorhexidine mouth rinse is typically prescribed to keep the area clean without mechanical disruption. This is a standard post-operative protocol used after many periodontal surgeries to reduce bacterial load while the tissue heals.
Full Recovery Timeline
The graft site typically heals enough for normal daily activities within two to three weeks. The palatal donor site may feel sore for a similar period, though some patients report the palate is more uncomfortable than the graft site itself.
Full maturation of the grafted tissue takes several months. During this time, the tissue blends in color and texture with the surrounding gum. Follow-up visits at one week, one month, and three months are common so the periodontist can monitor healing.
Results vary by individual. Factors that influence the outcome include the severity of recession, the thickness of remaining tissue, the patient's oral hygiene habits, and whether the original cause of recession has been eliminated.
Cost of a Single-Tooth Gum Graft
A single-tooth gum graft typically ranges from $600 to $1,500. Costs vary by location, provider, and case complexity.
The main factors that affect cost include the type of graft material, the periodontist's geographic area, and whether sedation is used. A connective tissue graft using your own palatal tissue is generally less expensive than a procedure using processed donor tissue (ADM), because the donor material itself has a cost.
Dental insurance may cover part of the cost if the graft is considered medically necessary, meaning it protects the tooth from further damage rather than being purely cosmetic. Check with your insurance provider before scheduling. Many periodontist offices also offer payment plans.
Keep in mind that treating one tooth early may cost less overall than waiting until multiple teeth are affected. Larger grafts covering several teeth require more tissue, more surgical time, and higher fees.
When to See a Periodontist
See a periodontist when you notice recession on any tooth, even if it is not causing pain. Early evaluation gives you the most treatment options and the best chance of full root coverage.
Your general dentist may be the first to point out recession during a routine exam. In many cases, the general dentist will refer you to a periodontist for treatment. A periodontist has completed an additional two to three years of specialized training in gum and bone conditions after dental school. [2]
You should seek a specialist evaluation if you notice any of the following signs on a single tooth:
- The tooth appears longer than its neighbors.
- You can feel a notch or step where the gum meets the tooth.
- The tooth is sensitive to cold, heat, or sweet foods near the gumline.
- The gum tissue around one tooth looks red, swollen, or has pulled away from the tooth.
- You see a dark yellow or brownish area near the gumline, which may be exposed root surface.
