Receding gums don’t grow back on their own, but you can stop them from getting worse and, in many cases, restore lost tissue with professional treatment. A long-term study tracking patients for up to 27 years found that untreated recession progressed by about 0.7 to 1.0 mm over time. The good news is that a combination of habit changes, the right products, and targeted dental procedures can protect exposed roots and rebuild your gumline.
Why Gums Recede in the First Place
Understanding the cause matters because treatment depends on it. The most common drivers of gum recession are brushing too hard, plaque and tartar buildup, and periodontal disease. But several less obvious factors also play a role: crooked or rotated teeth, lip or tongue piercings that rub against the gums, tobacco use, and prior orthodontic treatment like braces.
Periodontal disease is the most destructive cause. When plaque hardens into tartar below the gumline, it triggers chronic inflammation that breaks down both gum tissue and the bone supporting your teeth. Other causes like aggressive brushing tend to produce recession without the bone loss, which actually makes those cases easier to treat surgically.
Fix Your Brushing Technique First
If you’re brushing hard with a stiff-bristled brush, you may be causing or accelerating your own recession. Switch to a soft-bristled brush and learn the Modified Bass technique, which is recommended by the American Dental Association. Hold the brush at a 45-degree angle to your gumline, make short back-and-forth strokes, then sweep the bristles away from the gum toward the edge of the tooth. This cleans effectively without traumatizing the tissue.
An electric toothbrush with a pressure sensor can help if you tend to push too hard. The goal is thorough plaque removal with minimal force.
Choose the Right Toothpaste
Not all fluoride toothpastes offer the same protection for receding gums. Toothpastes containing stannous fluoride outperform those with only sodium fluoride in several ways that matter when your roots are exposed. In one study, a stannous fluoride formula reduced enamel breakdown by 67%, compared to just 19% for a sodium fluoride-only product. Stannous fluoride also reduces the viability of dental plaque more effectively, which helps control gingivitis, the precursor to more serious gum disease.
The tin component in stannous fluoride creates a modified layer on tooth surfaces that resists dissolving, and it disrupts enzymes that certain bacteria use to build up biofilm. For people with recession, this translates to better protection of vulnerable root surfaces and less gum inflammation.
Managing Root Sensitivity
Exposed tooth roots lack the protective enamel that covers the crown of the tooth, so hot, cold, or sweet foods can trigger sharp pain. Desensitizing toothpastes containing 5% potassium nitrate work by calming the nerve inside the tooth. Desensitizing mouthwashes with 3% potassium nitrate offer similar relief. Using either one twice daily can meaningfully reduce discomfort over a few weeks.
Your dentist can also apply professional-strength desensitizing agents or paint a fluoride varnish directly onto exposed roots for more immediate relief.
Professional Cleaning for Gum Disease
When recession is driven by periodontal disease, the first step is a deep cleaning called scaling and root planing. This removes tartar deposits from below the gumline and smooths the root surface so gum tissue can reattach. The procedure is most beneficial when pocket depths (the gaps between your gums and teeth) reach about 4 to 6 mm, where it produces the best gains in tissue reattachment. Expect pocket depths to decrease by roughly 0.7 to 1.1 mm after treatment, depending on the pattern of bone loss.
Deep cleaning alone won’t reverse recession, but it halts the disease process that’s making it worse. For many people with mild recession caused by gum disease, this stabilization is the most important intervention.
Gum Grafting Surgery
When recession is significant enough to cause sensitivity, aesthetic concerns, or risk to the tooth, surgical grafting can restore lost tissue. The type of graft your periodontist recommends depends on where the recession is and how much tissue remains.
Connective Tissue Graft
The most common approach takes a small piece of tissue from beneath the skin on the roof of your mouth and places it over the exposed root, then advances the surrounding gum tissue over it. Root coverage rates typically range from 70% to 86%. Recovery takes one to two weeks, during which you’ll need to eat soft foods and avoid brushing the surgical site.
Free Gingival Graft
This method takes tissue directly from the surface of the palate and is best suited for non-visible areas, particularly the lower front teeth where the gum tissue tends to be very thin. It increases the band of firm, protective gum tissue by 2 to 6 mm. Root coverage is less predictable (41% to 76%), but the primary goal is usually to create a thicker, more resilient gumline. The trade-off: two healing sites, more post-operative discomfort, and the grafted tissue may not perfectly match the surrounding color.
Pinhole Surgical Technique
A newer, minimally invasive option that requires no incisions or sutures. The periodontist makes a small pinhole in the gum tissue above (or below) the recession, then uses instruments to loosen and reposition the existing tissue over the exposed root. Collagen strips are placed to hold everything in position. Recovery is dramatically faster. Most patients experience only minor swelling by day two and feel nearly fully healed within three to five days, compared to two weeks or more for traditional grafting. Both approaches are effective, though long-term comparative data is still limited.
How Recession Severity Affects Outcomes
Dentists classify recession into stages that predict how much root coverage surgery can achieve. The key factor is whether you’ve lost bone and tissue between the teeth, not just on the front-facing surface.
- Mild recession (no bone loss between teeth): Complete root coverage is realistic. These cases respond best to grafting, with the highest success rates across all surgical techniques.
- Moderate recession (some bone loss between teeth): Partial root coverage is achievable, typically 50% to 83% depending on the technique used. Complete coverage is possible in about half of cases.
- Severe recession (significant bone loss between teeth): Full root coverage is unlikely. Treatment focuses on stopping progression, reducing sensitivity, and protecting the tooth from further damage rather than restoring the original gumline.
Signs That Need Prompt Attention
Mild recession that’s stable and not causing symptoms can often be monitored with regular dental visits. But certain signs indicate active disease that needs treatment sooner rather than later: pus between teeth and gums, teeth that feel loose or have shifted position, persistent bad breath that doesn’t resolve with brushing, and gums that bleed easily. Loose teeth in particular signal advanced bone loss. The sooner you address active periodontal disease, the more tissue and bone you preserve for any future treatment.
