Once gum tissue has receded, it does not grow back on its own. But you can stop recession from getting worse, and in many cases, a dentist can restore lost tissue with a grafting procedure. The key is addressing the specific cause, whether that’s brushing habits, gum disease, grinding, or something structural about your teeth and jawbone.
Why Gums Recede in the First Place
Gum recession happens when the tissue around your teeth pulls back or wears away, exposing more of the tooth or its root. There are two broad categories of causes: chronic low-level trauma and inflammatory disease.
The most common form of trauma is aggressive toothbrushing. Scrubbing hard with a stiff-bristled brush over delicate gum margins, day after day, gradually pushes tissue downward. These cases usually show up alongside worn-down enamel near the gumline from the same abrasive motion. Teeth grinding and clenching (bruxism) is another mechanical cause. The excessive force stretches the fibers connecting your teeth to the surrounding bone, triggering a chain of chemical signals that promote bone loss at the top of the socket. As the bone recedes, the gum tissue follows.
Chronic gum disease (periodontitis) is the other major driver. When plaque and tartar build up below the gumline, the resulting inflammation breaks down both the connective tissue and the bone that support your gums. As that foundation erodes, gums migrate downward and roots become exposed. Some people are also structurally predisposed to recession. If the bone covering the front of a tooth root is naturally thin or absent (a condition called dehiscence), even mild irritation from plaque or brushing can trigger tissue loss. This is especially common on upper canines and lower front teeth.
Fix Your Brushing Technique
Switching to a soft-bristled toothbrush is the single easiest change you can make. Brush twice a day, but focus on gentle, short strokes angled at about 45 degrees toward the gumline rather than sawing back and forth across your teeth. The goal is to sweep plaque away from the gum margin, not scrub it off with force. If you notice your bristles are splayed flat within a few weeks, you’re pressing too hard.
Electric toothbrushes with pressure sensors can help if you tend to bear down without realizing it. Many models will pause or flash a light when you apply too much force. Flossing daily matters too, not because it directly prevents recession, but because it removes plaque from between teeth where your brush can’t reach, reducing the inflammation that leads to bone and tissue loss.
Address Grinding and Clenching
If you grind your teeth at night, a custom mouth guard from your dentist can absorb the forces that would otherwise transfer into your gums and jawbone. Store-bought guards are cheaper, but custom-fitted versions provide significantly better protection because they distribute pressure evenly across your bite. Grinding doesn’t just wear down enamel. The constant overload on periodontal fibers promotes bone resorption right where the bone meets the gum, which is exactly where recession starts.
Quit Tobacco and Vaping
Smoking is one of the strongest risk factors for gum disease and recession. Vaping isn’t a safe alternative for your gums, either. Research links e-cigarette use to increased rates of gingivitis and periodontitis, along with reduced antioxidant capacity in saliva (which is one of your mouth’s natural defenses against bacterial damage). People who vape report more gum pain and oral symptoms than non-smokers, though generally less than traditional cigarette smokers. Quitting either habit slows the progression of gum disease and gives treatment a better chance of working.
Professional Cleaning and Deep Cleaning
Regular dental cleanings remove tartar that you can’t get rid of at home. When gum disease has already set in, your dentist may recommend scaling and root planing, a deeper cleaning that goes below the gumline to scrape away hardite deposits and smooth the root surface so gum tissue can reattach more easily.
A meta-analysis of 11 randomized trials found that scaling and root planing improved clinical attachment (how tightly gum tissue grips the tooth) by about half a millimeter compared to no treatment, measured at six months or longer. That might sound small, but in the context of gum tissue, it’s meaningful. Eight trials also showed significant reductions in pocket depth at follow-ups ranging from one to seven months. In cases where pockets measured 4 millimeters or more, recession actually decreased after treatment. For shallower pockets (1 to 3 mm), the procedure maintained stability rather than producing visible improvement.
Scaling alone isn’t enough for active periodontitis. Your dentist will likely combine it with ongoing maintenance visits, typically every three to four months rather than the standard six, to keep bacteria from re-establishing below the gumline.
Gum Graft Surgery
When recession is significant and you’ve already lost tissue, grafting is the standard way to restore it. A periodontist takes a small piece of tissue, usually from the roof of your mouth, and stitches it over the exposed root. The graft integrates with your existing tissue over time, covering the root and rebuilding the gumline.
Recovery typically takes one to two weeks, though some cases take longer. You’ll have a follow-up appointment about a week after surgery. During recovery, expect to eat soft foods and avoid brushing the surgical site directly. The roof of your mouth, if that’s where tissue was harvested, can be sore for several days. Gum grafting works best for patients with significant tissue loss or those who need substantial reconstruction of the gumline.
The Pinhole Surgical Technique
For mild to moderate recession, a newer option called the Pinhole Surgical Technique offers a less invasive alternative to traditional grafting. Instead of cutting and stitching a tissue graft, the periodontist makes a tiny hole in the gum tissue above the receded area and gently repositions the existing tissue downward to cover the exposed root. Small collagen strips are placed underneath to stabilize the tissue and encourage healing.
The advantages are real: no incisions, no sutures, and the ability to treat multiple teeth in one session. Healing takes days rather than weeks, and patients see an immediate improvement in their gumline. The trade-off is that it’s not appropriate for severe recession or cases involving major bone loss, where traditional grafting with new tissue is still the better option.
Structural Factors You Can’t Control
Some causes of recession aren’t behavioral. If your teeth are naturally positioned outside the arch of bone (think of crowded or protruding teeth), the thin or absent bone on the outer surface makes recession far more likely. High frenulum attachments, where the small band of tissue connecting your lip or tongue to the gum sits too close to the tooth margin, can pull on gum tissue and contribute to retraction, especially when combined with plaque buildup.
Orthodontic treatment can sometimes help by moving teeth into better alignment within the bone, but it can also cause recession if teeth are moved through thin bone without careful planning. If your dentist identifies structural risk factors, they may recommend preventive grafting to reinforce thin tissue before recession becomes visible.
How Severity Shapes Your Options
Dentists classify recession into stages based on how far the tissue has pulled back and whether the bone between teeth has been lost. In early stages, where the gum has receded but the bone and tissue between your teeth remain intact, the outlook is excellent. Grafting or pinhole procedures can fully cover the exposed root. Once bone loss extends to the spaces between teeth, complete coverage becomes harder to achieve, and treatment focuses more on stopping further progression than on cosmetic restoration.
The practical takeaway: the earlier you act, the more reversible the damage. If you notice your teeth look longer than they used to, feel a notch near the gumline, or experience sensitivity to cold along certain teeth, those are signs recession has already started. Getting evaluated while you’re still in an early stage gives you the widest range of treatment options and the best cosmetic outcomes.
