Once gum tissue has pulled away from your teeth, it doesn’t grow back on its own. But you can stop the process from getting worse, and in moderate to severe cases, dental procedures can restore lost coverage. The key is identifying what’s driving the recession and addressing it directly, whether that’s how you brush, untreated gum disease, or a grinding habit you didn’t know you had.
Why Gums Recede in the First Place
Gum recession happens when the tissue surrounding your teeth wears away or pulls back, exposing more of the tooth or its root. The two broadest categories are bacterial damage and mechanical damage, and many people have both working against them at the same time.
On the bacterial side, plaque and tartar buildup triggers inflammation that gradually destroys the gum tissue and the bone underneath it. This is periodontal disease, and it’s the single biggest driver of recession. On the mechanical side, brushing too hard, grinding your teeth at night, or even lip and tongue piercings can physically wear gum tissue down over time. Misaligned teeth create uneven pressure that accelerates the problem. Smoking and chewing tobacco restrict blood flow to the gums, making them thinner and more vulnerable to both infection and physical stress.
Genetics also play a role. Some people are simply born with thinner gum tissue, which means less margin for error before recession becomes visible. If your parents dealt with receding gums, you’re more likely to as well, even with solid oral hygiene.
What You Can Do at Home
The most effective thing you can do right now is change how you brush. Aggressive brushing is one of the most common and most fixable causes of recession. The technique recommended by the American Dental Association is called the Modified Bass method: hold your toothbrush at a 45-degree angle to the gum line, then move it gently back and forth in short strokes for each tooth. After that, sweep the brush away from the gum toward the edge of the tooth. The motion should feel light and controlled, not like you’re scrubbing a surface clean.
Switch to a soft-bristled toothbrush if you haven’t already. Medium and hard bristles cause more abrasion than most people realize, especially along the gum line. Electric toothbrushes with pressure sensors can help if you tend to push too hard, since they alert you or stop rotating when you apply excessive force.
If you grind or clench your teeth, especially during sleep, that repetitive pressure pushes gums downward over time. A custom-fitted mouth guard from your dentist provides the most effective protection against this. You can also buy over-the-counter night guards, but they fit less precisely and offer less reliable protection. Wearing a guard consistently reduces wear and tear on both teeth and gum tissue.
If you smoke or use chewing tobacco, quitting removes one of the strongest ongoing risk factors for recession. Tobacco restricts the blood supply that gum tissue depends on to stay healthy and repair itself.
Deep Cleaning: The First Clinical Step
When recession is caused or worsened by gum disease, your dentist will typically recommend scaling and root planing before anything else. This is a nonsurgical deep cleaning that goes beneath the gum line, where regular brushing and flossing can’t reach.
During the procedure, your gums are numbed with local anesthesia. Your dentist or hygienist then removes plaque and tartar from the tooth surfaces both above and below the gum line using hand instruments or ultrasonic tools. After that, they smooth the root surfaces, which makes it harder for bacteria to reattach and gives gum tissue a better chance of healing snugly against the tooth. Antibiotics may be placed around the roots or prescribed to take afterward.
The whole process takes one to two hours. Some dentists complete it in a single visit, while others split it across two appointments, cleaning half the mouth each time. Ideally, you only need this done once. After the bacteria and tartar are removed, consistent brushing, flossing, and regular dental cleanings should keep things from regressing. The goal is to halt the disease process so your gums can stabilize where they are.
Surgical Options for More Advanced Recession
When recession has progressed enough to expose tooth roots, cause sensitivity, or create cosmetic concerns, surgery can restore gum coverage. The two main approaches are traditional gum grafting and a newer technique called the Pinhole Surgical Technique.
Traditional Gum Grafting
In a gum graft, tissue is taken from another area of your mouth (usually the roof) and stitched over the exposed root. This method requires incisions and sutures, and recovery typically takes one to two weeks. During that time, you’ll need to stick to soft foods and follow careful hygiene instructions to let the graft heal properly. Gum grafting is particularly well suited for patients with significant tissue loss or areas that need extensive reconstruction.
Pinhole Surgical Technique
This minimally invasive alternative involves no incisions or stitches. Instead, the dentist makes a small pinhole in the existing gum tissue and repositions it to cover the exposed root. Because there’s no cutting or suturing, recovery is dramatically faster. Most patients return to normal activities within a day or two. The Pinhole Technique works best for mild to moderate recession and is a good option if you want less downtime.
Both procedures are effective at restoring gum coverage. Your dentist will recommend one based on how much tissue has been lost, the location of the recession, and the condition of the underlying bone.
How Dentists Assess the Severity
Not all recession is the same, and the treatment path depends heavily on what’s happening between the teeth, not just on the outer surface you can see. Dentists now classify recession into three types based on a system adopted at the 2017 World Workshop on Periodontal Diseases.
Type 1 means the gums have pulled back on the outer surface of the tooth, but the tissue between the teeth is still intact. This is the most treatable form, with the highest chance of full root coverage through grafting or the Pinhole Technique. Type 2 means some of the tissue between the teeth has also been lost, though not more than what’s been lost on the outer surface. Partial coverage is still possible, but complete restoration becomes harder. Type 3 is the most advanced: the tissue loss between the teeth exceeds what’s visible on the outside. Full root coverage is unlikely at this stage, though treatment can still improve things.
This classification matters because it tells your dentist what’s realistic. If you’re told you have Type 1 recession, the prognosis for restoring your gum line is quite good. The further along it is, the more the focus shifts from restoration to preventing further loss.
A Daily Routine That Protects Your Gums
Stopping recession long-term comes down to removing the forces that caused it while keeping bacteria under control. A practical daily approach includes brushing twice a day with a soft-bristled brush using gentle, angled strokes. Floss or use interdental brushes once a day to clean the spaces your toothbrush can’t reach, since plaque left between teeth is a primary driver of the gum disease that causes recession.
An antimicrobial or fluoride mouthwash can add another layer of protection, particularly if you’re already dealing with early-stage gum disease. If you grind your teeth, wear your night guard every night, not just occasionally. And keep up with professional cleanings on whatever schedule your dentist recommends, which may be every three to four months rather than six if you’ve had gum disease.
Recession tends to progress slowly, which means small, consistent changes in your daily habits can make a meaningful difference over months and years. The damage already done may require professional treatment to correct, but how much further it goes is largely within your control.
