What This Guide Covers and Who It Is For
This guide compares four gum graft types so you can understand your options before meeting with a periodontist. A gum graft is a surgical procedure that adds tissue to areas where your gums have pulled away from your teeth. This pulling away is called gum recession.
Gum recession exposes the roots of your teeth. Exposed roots can cause sensitivity to hot and cold foods. They also raise your risk for root cavities and further tissue loss. [1]
If your dentist or periodontist has mentioned gum grafting, this guide will help you understand each technique, how recovery compares, and what factors go into choosing one over another. The information here applies to adults of all ages who have been diagnosed with gum recession.
The Four Main Types of Gum Grafts
Each graft type uses a different tissue source or technique to rebuild lost gum tissue. Your periodontist will recommend one based on the location of your recession, how much tissue remains, and your overall oral health. [1]
Connective Tissue Graft (CTG)
The connective tissue graft is the most widely used technique for root coverage. It is often called the gold standard for treating gum recession. [1]
During this procedure, a periodontist creates a small flap in the roof of your mouth (the palate). A thin layer of connective tissue is removed from under that flap. The tissue is then stitched over the exposed root at the recession site. The flap on the palate is closed with stitches as well.
This technique works well when one or more teeth have moderate recession and the goal is to cover visible root surfaces. Because the tissue comes from beneath the surface of the palate, the donor site typically heals with less discomfort than other palatal harvesting methods.
Results vary, but connective tissue grafts typically achieve good root coverage in many cases. The grafted tissue tends to blend well with the surrounding gum color and texture over time.
Free Gingival Graft (FGG)
The free gingival graft is best for adding thickness to thin gum tissue rather than covering exposed roots. It is commonly used as a preventive measure when gums are thin and at risk of further recession.
In this procedure, a small piece of tissue is taken directly from the surface of the palate. Unlike the connective tissue graft, the tissue is not taken from under a flap. It is removed from the outer layer. This tissue is then placed at the area where more thickness is needed.
Because the tissue is taken from the surface, the donor site on the palate is an open wound that heals on its own. This can be more uncomfortable during recovery than the connective tissue approach. The color match at the graft site may also be less natural, since the surface palatal tissue can appear lighter than the surrounding gums.
Periodontists often choose this graft for lower front teeth where the tissue is naturally thin. Adding bulk to these areas can help prevent future recession.
Pedicle Graft (Laterally or Coronally Positioned Flap)
The pedicle graft uses tissue right next to the recession site, so there is no need for a separate donor site on the palate. This is a key advantage for patient comfort.
The periodontist creates a flap of tissue from the gum adjacent to the exposed root. The flap stays attached at one end, which preserves its blood supply. It is then rotated or shifted over the recession area and stitched into place.
This technique requires enough healthy gum tissue next to the recession site to create the flap. Not every patient is a candidate. When there is sufficient tissue, pedicle grafts typically heal faster than other graft types because the blood supply is never fully cut off.
Pedicle grafts can achieve good root coverage and tend to heal with a natural appearance. They are most often used for isolated areas of recession where neighboring tissue is thick and plentiful.
Allograft (Donor Tissue Such as AlloDerm)
An allograft uses processed human donor tissue instead of tissue from your own mouth. AlloDerm is one of the most recognized brand names, but several products are available.
The donor tissue is sterilized and processed to remove cells, leaving behind a collagen scaffold. This scaffold acts as a framework that your own tissue grows into over the following weeks and months. Because no tissue is taken from your palate, you have only one surgical site to heal.
Allografts are often chosen when a patient has thin palatal tissue, when multiple teeth need grafting at once, or when a patient prefers to avoid a second wound site. Recovery comfort is typically better because there is no palatal donor site.
Outcomes with allografts can be very good, though some studies suggest that autografts (tissue from your own body) may achieve slightly higher rates of root coverage in certain situations. Your periodontist can explain how each option applies to your specific case.
What to Know Before Choosing a Gum Graft
Several practical factors affect which graft type is best for you. Understanding these details can help you have a more productive conversation with your periodontist.
Who Needs Gum Grafting and When
Gum grafting is typically recommended when recession has progressed enough to expose root surfaces, cause sensitivity, or put teeth at risk. [1] Mild recession may only need monitoring, while moderate to severe cases usually benefit from surgical repair.
There is no strict age cutoff. Adults of any age can be candidates as long as they are in reasonable overall health. Younger patients with thin tissue types may receive a free gingival graft as a preventive step. Older patients with active recession are more likely to need a connective tissue graft or allograft for root coverage.
Timing matters as well. Gum recession does not reverse on its own. Waiting too long can lead to bone loss around the tooth, which makes grafting less predictable. Your periodontist will assess bone levels using X-rays before recommending a plan. [1]
How to Prepare for Gum Graft Surgery
Preparation starts with a thorough periodontal evaluation. Your periodontist will measure your recession, check for gum disease (periodontal disease), and take images of the area. Any active gum disease typically needs to be treated before grafting.
In the days before surgery, you may be asked to rinse with an antimicrobial mouthwash. If you take blood thinners, your periodontist and physician will coordinate any adjustments. Eating a good meal before the appointment is generally recommended, since you will be on a soft food diet afterward.
Ask your periodontist about sedation options. Most gum grafts are done under local anesthesia (numbing the area), but oral sedation or nitrous oxide may be available for patients who feel anxious.
What to Expect During and After the Procedure
Gum graft surgery is typically an outpatient procedure that takes 60 to 90 minutes, depending on how many teeth are treated.
During the Procedure
The area is numbed with local anesthesia. You should feel pressure but not pain during the surgery. Your periodontist will prepare the recession site by gently cleaning the root surface and creating a small pouch or bed where the graft will be placed.
If you are receiving a connective tissue graft or free gingival graft, donor tissue is harvested from your palate at this point. For a pedicle graft, the adjacent tissue is carefully released and repositioned. For an allograft, the processed donor tissue is trimmed to fit the site.
The graft is secured over the root or recession area with small sutures. A periodontal dressing (a soft protective bandage) may be placed over the site. The entire appointment, including preparation and postoperative instructions, usually lasts about two hours.
Recovery Timeline and Tips
Recovery takes 1 to 3 weeks for most graft types. The first 48 hours involve the most discomfort. Swelling, mild bruising, and soreness at the graft site and donor site (if applicable) are normal.
Pedicle grafts typically have the shortest recovery because there is no palatal wound. Allografts also tend to be more comfortable since only one site is healing. Connective tissue grafts and free gingival grafts involve palatal healing, which some patients describe as the most uncomfortable part.
During recovery, stick to soft, cool foods. Avoid brushing or flossing the surgical area until your periodontist says it is safe, usually after the first follow-up visit at 7 to 10 days. Rinsing gently with a prescribed antimicrobial rinse helps keep the area clean. Most patients return to normal activities within a few days, but strenuous exercise should be avoided for about a week.
Full maturation of the grafted tissue can take several months. The color and texture of the graft continue to improve during this time. Your periodontist will schedule follow-up visits to monitor healing.
Gum Graft Cost and Insurance Considerations
Costs for gum graft surgery vary by location, provider, and case complexity. Several factors influence the final price.
The type of graft matters. Allografts often cost more per tooth due to the price of the processed donor material. Connective tissue grafts and pedicle grafts use your own tissue, so material costs are lower, though the surgical skill and time involved still affect the fee. Free gingival grafts tend to be similar in cost to connective tissue grafts.
Expect to see cost ranges from roughly $600 to $3,000 per tooth for gum graft procedures. Treating multiple teeth at one appointment may reduce the per-tooth cost in some practices. These figures are estimates and can vary significantly. Always request a written treatment plan with itemized costs before scheduling surgery.
Many dental insurance plans classify gum grafting as a medically necessary periodontal procedure and may cover a portion of the cost. However, coverage varies widely by plan. Some plans group gum grafting under major procedures with higher out-of-pocket costs, while others may have waiting periods or annual maximums that limit benefits. Contact your insurance company before the procedure to understand your specific benefits, including deductibles, co-pays, and annual maximums. [2]
When to See a Periodontist for Gum Recession
A periodontist is a dentist with additional years of training focused on the gums, bone, and supporting structures of the teeth. [1] They are the specialists most qualified to diagnose gum recession and perform graft surgery.
Your general dentist may notice early recession during a routine exam. In mild cases, monitoring and improved brushing technique may be sufficient. You should be referred to a periodontist when recession is progressing, when root surfaces are exposed, when you have sensitivity that does not respond to desensitizing toothpaste, or when bone loss is suspected.
Other signs that warrant a specialist visit include gums that bleed regularly, teeth that appear longer than they used to, or a notch you can feel at the gum line. These symptoms can indicate that recession is advancing and may benefit from grafting before further damage occurs. [1]
If you have already been diagnosed with periodontal disease, a periodontist can treat the disease and address the recession in a coordinated plan. Grafting over untreated disease is not recommended because active infection can cause graft failure.
