What This Guide Covers and Who It Is For
This guide explains why some patients develop gum recession after orthodontic treatment and what a gum graft involves. It is written for adults, teens, and parents who have noticed receding gums during or after braces.
Gum recession means the gum tissue pulls away from the tooth, exposing part of the root. When this happens after braces, a gum graft may be needed to cover the root and prevent sensitivity, decay, or further tissue loss. The American Academy of Periodontology identifies gum grafting as one of several procedures used to treat recession and protect long-term tooth health. [2]
You will find information here on timing, the grafting procedure itself, recovery, costs, and when to see a specialist. If you already know you need a periodontist, you can visit the periodontics page to find one near you.
Why Gum Recession Happens After Braces
Braces move teeth through bone, and that movement can thin the gum tissue or bone supporting certain teeth. When the bone or tissue is already thin, orthodontic forces may push a tooth partially outside the bone envelope, leaving the root less protected.
Which Teeth Are Most at Risk
The lower front teeth (mandibular incisors) are the most common site for recession after orthodontic treatment. These teeth naturally sit in a narrow ridge of bone. When braces tip or push them forward, the thin bone on the outer (facial) side can shrink further.
Upper canines and premolars may also be affected if they were moved a significant distance. Teeth that required large rotations or were severely crowded before treatment carry a higher risk. The risk is not the same for every patient. Genetics, tissue thickness, brushing habits, and the direction of tooth movement all play a role.
Thin vs. Thick Gum Tissue
People are born with different gum tissue types. Some have thick, dense tissue that resists recession well. Others have thin, delicate tissue that is more vulnerable to breakdown under orthodontic forces.
A periodontist can measure tissue thickness before orthodontic treatment begins. If the tissue is very thin, preventive grafting before or during braces may be recommended. This is sometimes called a "preemptive" graft. It adds tissue volume so the gums can tolerate tooth movement without receding.
Other Factors That Contribute to Recession
Orthodontic movement is rarely the only cause. Hard brushing during braces can damage gum tissue already under stress. Plaque buildup around brackets leads to inflammation, which weakens the tissue attachment. The American Dental Association recommends gentle brushing with a soft-bristled brush to protect gum health during orthodontic treatment. [3]
Teeth grinding (bruxism) adds lateral force that compounds orthodontic stress. Smoking reduces blood flow to the gums and slows healing. When several of these factors overlap, recession becomes more likely.
Timing, Preparation, and What Patients Should Know
Most periodontists recommend waiting 3 to 6 months after braces are removed before deciding on a gum graft. This waiting period allows the gum tissue and bone to stabilize in their new positions.
Why the Waiting Period Matters
When braces come off, the tissues are still adapting. Gums that look receded at debonding (the appointment when brackets are removed) may partially recover on their own once the hardware is gone and inflammation subsides. Evaluating too early can lead to unnecessary surgery, while evaluating too late may allow further damage.
Your orthodontist will typically refer you to a periodontist for a gum evaluation once the tissue has had time to settle. During that evaluation, the periodontist measures probing depths, tissue thickness, and the amount of root surface exposed.
Age and Candidacy
Gum grafting can be performed on teens and adults. In younger patients, the periodontist may prefer to wait longer because the tissues are still developing and may recover more on their own. For adults over 40, healing time may be slightly longer, but age alone does not rule out a successful graft.
Good candidates are non-smokers with controlled oral hygiene and no active gum disease (periodontal disease). If gum disease is present, it must be treated first. The graft will not succeed in an environment with active bacterial infection. [2]
How to Prepare for a Gum Graft
Before surgery, the periodontist may ask you to use an antimicrobial mouth rinse for a week. You should avoid aspirin and other blood-thinning medications if your doctor agrees. Arrange soft foods for the first week after surgery. Plan to take one to two days off from work or school.
Your periodontist will review your medical history and any medications. Be sure to mention if you take blood thinners, bisphosphonates, or immunosuppressants, as these can affect healing.
What Happens During and After Gum Graft Surgery
A gum graft is an outpatient procedure that typically takes 60 to 90 minutes per surgical site. You will go home the same day.
Types of Gum Grafts
There are three main types. A connective tissue graft uses tissue from under the surface layer of the roof of the mouth. The periodontist creates a small flap, removes a piece of connective tissue, and places it over the exposed root. This is the most common technique for root coverage.
A free gingival graft takes tissue directly from the surface of the palate (roof of the mouth). It is used more often to thicken thin gum tissue than to cover roots. A pedicle graft rotates a flap of gum tissue from the area next to the recession site. This method works only when there is enough adjacent tissue to share.
Some cases use allograft material, which is processed human donor tissue, instead of tissue from the patient's own palate. Recent case studies have also explored the use of growth factors, such as recombinant human fibroblast growth factor-2 (rhFGF-2), combined with connective tissue grafts to enhance root coverage outcomes. [1]
The Procedure Step by Step
The periodontist numbs the area with local anesthesia. Sedation options such as oral sedation or nitrous oxide may be available for patients with dental anxiety. The exposed root is cleaned and any plaque or tartar is removed.
The graft tissue is then placed over the root and sutured (stitched) into position. A periodontal dressing, which is a soft bandage, may be placed over the site to protect it. The entire process is performed under magnification for precision.
If multiple teeth in the same area need grafting, they can sometimes be treated in one visit. Treating teeth on both sides of the mouth at the same time is less common because it makes eating difficult during early recovery.
Recovery and Healing
Most patients feel mild to moderate discomfort for the first two to three days. Over-the-counter pain relievers typically manage this well. The palate donor site, if used, may feel sore for up to two weeks.
Stick to soft foods like yogurt, scrambled eggs, and smoothies for the first week. Avoid crunchy, spicy, or acidic foods. Do not brush or floss the surgical area until your periodontist gives you clearance, usually at your one-week follow-up visit.
The graft site will look white or reddish at first. Over the next two to four weeks, the tissue gradually blends with the surrounding gum color. Full maturation of the graft takes three to six months. Your periodontist will schedule follow-up appointments to track healing.
Success Rates and Outcomes
Root coverage with connective tissue grafts typically achieves 90% or greater coverage of the exposed root when performed by a trained periodontist. Results vary based on the depth of recession, the location of the tooth, blood supply, and patient factors like smoking status.
Case studies exploring connective tissue grafts combined with growth factors such as rhFGF-2 have shown promising early results for root coverage, though larger controlled trials are needed to confirm these findings. [1] Complete (100%) root coverage is more likely when the recession is shallow and the surrounding bone between the teeth (interdental papillae) is intact.
Gum Graft Cost and Insurance Coverage
Gum grafting typically costs between $600 and $3,000 per tooth. Costs vary by location, provider, and case complexity.
The price depends on the type of graft, the number of teeth treated, and whether donor tissue material is used instead of tissue from the palate. Using allograft material often adds to the cost because the processed tissue itself is an additional expense. Treating multiple adjacent teeth in one surgery may reduce the per-tooth cost compared to separate procedures.
Many dental insurance plans classify gum grafting as a medically necessary periodontal procedure and cover a portion of the cost. Coverage varies widely. Some plans cover 50% to 80% after the deductible. Others have annual maximums that limit total reimbursement. Call your insurance provider before scheduling and ask for a pre-authorization to understand your out-of-pocket responsibility.
If you do not have insurance, ask the periodontist's office about payment plans. Some offices offer financing through third-party companies that spread the cost over several months.
When to See a Periodontist
See a periodontist if you notice any root exposure, tooth sensitivity along the gumline, or visible gum tissue loss after orthodontic treatment.
A general dentist can identify recession during a routine exam, but a periodontist has specialized training in gum tissue surgery and grafting techniques. The American Academy of Periodontology recommends that patients with moderate to severe recession be evaluated by a periodontist for treatment planning. [2]
You should also consider a periodontal evaluation before starting braces if you have naturally thin gum tissue, a history of recession, or previous periodontal disease. Early assessment can guide your orthodontist in planning tooth movements that minimize tissue damage.
Signs that indicate you should schedule an appointment include: teeth that appear longer than they used to, a notch you can feel at the gumline with your fingernail, increased sensitivity to hot or cold foods, or gums that bleed easily despite good brushing habits. These signs do not always mean you need a graft, but they warrant a professional evaluation.
