Gum tissue that has receded does not grow back on its own. Once the gum line pulls away from a tooth, the body cannot regenerate that tissue without intervention. But several treatments, from deep cleanings to surgical grafts to laser procedures, can restore lost gum tissue or reattach it to the tooth root. The right approach depends on how much tissue you’ve lost and what caused the recession in the first place.
Why Gums Don’t Regrow Naturally
Gum tissue is made largely of collagen, and the attachment between your gums and teeth relies on a specialized structure called the periodontal ligament. When gum disease, aggressive brushing, or other forces destroy this attachment, the body’s default healing response fills the gap with scar-like tissue rather than rebuilding the original architecture. Predictably regenerating the three-dimensional structure of healthy gum attachment, including bone, ligament, and the root-covering layer called cementum, remains one of the biggest challenges in dentistry.
That said, “rebuilding gums” doesn’t always require full regeneration. In many cases, the goal is to cover exposed roots, reduce deep pockets between teeth and gums, and stop the recession from getting worse. Those goals are very achievable.
Deep Cleaning: The Starting Point
If your gums have pulled away and formed pockets around the teeth, a deep cleaning (scaling and root planing) is typically the first step. This procedure removes bacteria and hardened deposits from below the gum line, then smooths the root surface so gum tissue can reattach more easily.
The results are modest but meaningful. Pockets measuring 4 to 6 millimeters deep typically shrink by about 1 mm after treatment, while deeper pockets of 7 to 12 mm can shrink by about 2 mm. Clinical attachment, the measure of how firmly gum tissue grips the tooth, improves by roughly 0.7 to 1.0 mm depending on the pattern of bone loss underneath. These gains matter because reducing pocket depth makes it harder for bacteria to recolonize and cause further damage.
Deep cleaning works best when pockets are deeper than about 3 mm. Shallower recession caused by brushing too hard or thin gum tissue usually needs a different approach.
Gum Graft Surgery
Connective tissue grafting is the most established way to physically rebuild a receded gum line. A periodontist takes a small piece of tissue, usually from the roof of your mouth, and stitches it over the exposed root. Donor tissue from a tissue bank can also be used, which avoids a second surgical site.
The grafted tissue integrates with your existing gums over the following weeks, creating a thicker, more protective gum line. Most people feel back to normal within about two weeks, though full healing takes longer. Grafting typically costs $600 to $1,200 per tooth, and multiple teeth can sometimes be treated in a single session.
This procedure has decades of data behind it and remains the gold standard for covering exposed roots, especially when recession is severe or localized to a few teeth.
Pinhole Surgical Technique
The pinhole technique is a minimally invasive alternative to traditional grafting. Instead of cutting and stitching tissue, the periodontist makes a tiny hole in the gum above the receded area, then loosens and repositions the existing tissue downward to cover the exposed root. Collagen strips are placed underneath to hold everything in position while it heals.
The appeal is a faster, less uncomfortable recovery with no tissue harvested from the roof of your mouth. It works best for patients with enough existing gum tissue that simply needs to be moved into the right position. Not every case of recession qualifies for this approach.
Laser Treatment (LANAP)
The LANAP protocol uses a specific type of laser to treat gum disease and stimulate regrowth of the attachment structures. The laser selectively removes diseased tissue and bacteria from periodontal pockets while leaving healthy tissue intact. A blood clot forms in the treated pocket, and the body rebuilds bone, cementum, and ligament attachment over the following months.
In 2016, the FDA cleared the PerioLase laser as the only device in medicine or dentistry capable of achieving true regeneration of the full attachment apparatus, not just repair, but regrowth of all three components needed for a functional tooth-to-bone connection. Histological studies have confirmed new cementum and new connective tissue attachment forming at treated sites, with no regeneration seen at control sites treated with conventional surgery.
LANAP costs $1,000 to $5,000 per quadrant (one-quarter of the mouth), making it a significant investment. It’s best suited for moderate to severe gum disease with bone loss, rather than cosmetic recession from overbrushing.
Regenerative Proteins and Growth Factors
During gum surgery, your periodontist may apply a protein gel derived from enamel matrix to the exposed root surface. This gel mimics the proteins that originally guided tooth development, stimulating cells in the periodontal ligament to rebuild bone and cementum. In animal studies, this approach increased new cementum formation by an average of 1.38 mm compared to untreated sites.
These proteins work best for specific types of bone defects, particularly vertical defects where bone has been lost along one side of a tooth root. They’re used as an add-on during surgical procedures rather than as a standalone treatment.
What Causes Recession in the First Place
Rebuilding your gums only works long-term if you address the root cause. The most common drivers are gum disease (bacterial infection that destroys the attachment), aggressive tooth brushing, thin or fragile gum tissue (often genetic), teeth grinding, tobacco use, and misaligned teeth that concentrate force unevenly.
Teeth grinding deserves special attention. Sleep grinding isn’t a direct cause of gum disease, but when gum disease already exists, grinding accelerates the damage and can push mild periodontitis into severe territory quickly. Daytime clenching may actually be worse for gum tissue than nighttime grinding. The sustained, low-level force compresses tiny blood vessels in the periodontal ligament, cutting off blood flow repeatedly and weakening the tissue’s ability to resist infection. If you grind or clench, a night guard is a critical part of protecting any gum rebuilding work you invest in.
How Brushing Habits Affect Recovery
A three-year clinical study tracked people with existing gum recession and found that both power and manual toothbrush users saw their recession decrease over time, from an average of about 2.3 mm to 1.8 mm. That’s a meaningful improvement just from consistent, gentle brushing technique. The power toothbrush group had a statistically lower risk of recession getting worse at individual tooth sites, likely because oscillating-rotating brushes do the scrubbing work for you, reducing the tendency to press too hard.
If you’re prone to aggressive brushing, switching to an electric toothbrush with a pressure sensor can help. But the technique matters more than the tool. Use soft bristles, hold the brush at a 45-degree angle to the gum line, and let the bristles do the work rather than forcing them against the tissue.
Nutrition for Gum Tissue Integrity
Vitamin C plays a direct role in gum health because collagen, the primary structural protein in gum tissue, cannot be produced without it. The periodontal ligament that anchors teeth to bone is made of collagen. When vitamin C levels drop too low, gums become fragile, bleed easily, and teeth can loosen. This is the mechanism behind scurvy, which historically manifested first as gum breakdown.
The recommended daily intake is 90 mg for men and 75 mg for women, with smokers needing an additional 35 mg per day. Most people get enough from a normal diet that includes fruits and vegetables, but if your diet is limited or you smoke, a supplement can fill the gap. The upper safe limit is 2,000 mg per day. Vitamin C also acts as an antioxidant in gum tissue and supports wound healing after any periodontal procedure.
Choosing the Right Approach
Your starting point depends on what’s happening in your mouth. Mild recession with no deep pockets often responds to improved brushing habits and watchful monitoring. Moderate recession with exposed roots but healthy bone underneath is a good candidate for grafting or the pinhole technique. Active gum disease with deep pockets needs scaling and root planing first, possibly followed by LANAP or surgical intervention if pockets don’t resolve.
A periodontist will measure your pocket depths, assess bone levels on X-rays, and evaluate the thickness and position of your remaining gum tissue before recommending a plan. Many people need a combination of approaches: a deep cleaning to control infection, followed by a graft or regenerative procedure to restore what was lost, and then a long-term maintenance routine to keep the results stable.
