Gum tissue that has pulled away from your teeth will not grow back on its own. Unlike skin or bone, gum tissue lacks the biological ability to regenerate once it’s lost. The good news: professional treatments can restore your gumline, and the right daily habits can stop recession from getting worse. How you proceed depends on how far the recession has progressed.
Why Gums Don’t Regrow on Their Own
When gums recede, the body tries to heal the area by filling it with fast-growing epithelial cells, the same type that line the inside of your mouth. These cells rush into the gap before the slower-growing tissues that actually anchor your teeth (bone, ligament, and root-covering material called cementum) have a chance to rebuild. The result is a patch of soft tissue that doesn’t reattach to the tooth root. This is the core biological problem, and it’s why every professional treatment for recession is designed to either block those fast-growing cells or physically reposition gum tissue back over exposed roots.
How to Tell How Far It’s Gone
Dentists measure the depth of the pocket between your gum and tooth using a small probe. Healthy gums sit snugly against teeth with pocket depths of 1 to 3 millimeters. Stage I gum disease involves pockets up to 4 mm. Stage II reaches 5 mm. Once pockets hit 6 mm or deeper, you’re in Stage III territory, where bone loss becomes a serious concern.
You can gauge your own situation at home to some degree. If you see more of your tooth than you used to, feel a notch near the gumline with your fingernail, or notice increased sensitivity to cold drinks, recession is underway. But you need a professional measurement to know how much attachment has been lost beneath the surface.
Deep Cleaning: The First Line of Defense
For mild to moderate recession caused by gum disease, the standard starting treatment is scaling and root planing. A dental professional uses ultrasonic and hand instruments to scrape away bacterial buildup and hardened tarite (calculus) from below the gumline, then smooths the root surfaces so gums can reattach more easily.
This procedure reliably reduces inflammation, shrinks pocket depths, and can produce modest reattachment in the weeks that follow. In clinical follow-ups, pocket depths drop significantly within the first six weeks. The catch is durability: at one year, some of that improvement tends to slip, with slight increases in pocket depth and attachment loss compared to the six-week mark. That’s why deep cleaning isn’t a one-time fix. It works best as part of an ongoing maintenance plan with regular follow-up visits.
Gum Grafting for Visible Recession
When recession is pronounced enough that tooth roots are visibly exposed, a graft is often the most reliable way to rebuild the gumline. In a connective tissue graft, a periodontist takes a small piece of tissue from the roof of your mouth (or uses donor tissue) and stitches it over the exposed root. The grafted tissue integrates with your existing gums over the healing period, which typically takes about two weeks before your mouth feels normal again.
A newer alternative is the Chao Pinhole Surgical Technique. Instead of cutting and stitching donor tissue, a periodontist makes a tiny needle-sized hole above the recession site, loosens the existing gum tissue through that opening, and slides it down to cover the exposed root. Recovery is dramatically faster. Most patients report feeling fine the next day with only over-the-counter pain relief, and the cosmetic results are visible immediately.
Both procedures can be enhanced with a protein gel derived from enamel (sold as Emdogain), which was FDA-approved in 1996 for treating gum defects. This gel mimics the proteins your body used to build tooth-supporting structures during development. Clinical studies show that when it’s applied during a graft procedure, it produces greater root coverage and more of the thick, protective gum tissue you want, with results lasting at least two years compared to grafting alone.
Laser Treatment for Regeneration
The laser-assisted new attachment procedure, or LANAP, uses a specific wavelength of laser energy to remove diseased tissue from deep pockets while leaving healthy tissue intact. What sets it apart from traditional surgery is the evidence for true regeneration. Histological studies (where treated tissue is examined under a microscope) have confirmed that LANAP can produce new cementum, new connective tissue attachment, and new bone, not just repair, but actual regrowth of the structures that hold teeth in place.
The FDA cleared the PerioLase laser used in LANAP in 2016 as the only device in medicine or dentistry shown to achieve regeneration of the full attachment apparatus: bone, ligament, and cementum together. In comparative studies, LANAP maintained its improvements in attachment and bleeding reduction more consistently at one year than scaling and root planing alone. It also causes minimal postoperative discomfort, making it appealing for patients who want to avoid scalpel-based surgery.
What You Can Do at Home
No home remedy will reverse recession that’s already happened. But the wrong daily habits can accelerate it, and the right ones can protect the results of any professional treatment you receive.
Brushing Technique Matters More Than Toothpaste
Aggressive brushing is one of the most common causes of recession in people who don’t have gum disease. The Modified Bass technique is considered the gold standard for removing plaque without damaging gum tissue. Angle your toothbrush at 45 degrees toward the gumline, use short back-and-forth strokes with gentle pressure, then sweep the bristles away from the gums toward the biting surface. Use a soft-bristled brush. If your bristles are splayed flat within a month, you’re pressing too hard.
Vitamin C and Gum Integrity
Vitamin C is essential for producing collagen, which makes up the structural framework of your gums, the ligaments that hold your teeth, and the blood vessels that supply them. A deficiency weakens all of these, leading to bleeding gums and increased tooth mobility. The recommended daily intake is 90 mg for men and 75 mg for women. Smokers need an extra 35 mg per day because smoking depletes vitamin C faster. Splitting your intake across multiple meals helps maintain steady levels. Citrus fruits, bell peppers, strawberries, and broccoli are all rich sources.
Night Guards for Grinders
If you clench or grind your teeth at night, the excessive force transfers directly through the tooth into the surrounding bone and gum tissue. Over time, this can drive recession even in mouths with no bacterial disease. A custom night guard from your dentist distributes that force more evenly and reduces the mechanical stress on your gums. Over-the-counter options exist but fit less precisely.
Quitting Smoking Changes the Odds Dramatically
Smoking is the single most impactful modifiable risk factor for gum recession and periodontitis. Current smokers are nearly five times more likely to have advanced gum disease than nonsmokers. The data on quitting is striking: in a U.S. national survey, periodontitis prevalence was 34.5% among current smokers but dropped to 19.3% in former smokers and 13.1% in people who never smoked. The probability of losing a tooth to gum disease drops by about 6% for every year you stay smoke-free.
Quitting also directly improves how well treatments work. Patients who stopped smoking showed significantly greater gains in clinical attachment, deeper reductions in pocket depth, and fewer sites with ongoing tissue loss compared to those who kept smoking. Current smokers who undergo periodontal treatment face an 80% recurrence rate over six years. For nonsmokers, that number is 44%.
Choosing the Right Treatment
The best approach depends on what’s causing your recession and how advanced it is. Recession from gum disease with deep pockets typically starts with scaling and root planing, potentially followed by LANAP or surgical intervention if pockets remain. Recession from aggressive brushing or grinding, where gums have pulled back but pockets are shallow, is better addressed with grafting or the pinhole technique to physically restore the gumline, combined with correcting the habit that caused it.
Mild recession (1 to 2 mm below where the gum should sit) may not need surgical treatment at all if it’s caught early and the cause is eliminated. Moderate to severe recession with exposed roots and sensitivity almost always benefits from a professional procedure. Your periodontist can map every tooth’s pocket depth, measure exactly how much attachment has been lost, and recommend the least invasive option that will produce lasting results.
